Proper Steam Bypass System Design Avoids Steam Turbine Overheating
The steam bypass system is generally used during the following modes of operation: start-up and shutdown, steam turbine trip, steam turbine no-load or low-load operation, and simple-cycle operation. On start-up, the isolation of the CTG/HRSG from the STG allows the CTG to be placed on load without delay and well before the heat-up and roll-off of the STG. In addition, a faster start-up of the STG is possible since the bypass system provides the capability of close temperature matching between the steam inlet temperature and the steam turbine metal temperature.

Upgrade FGD systems with an absorber tray says B&W
Retrofitting an absorber tray into an open spray tower is an effective way to maximize the contact between the flue gas and the slurry. The tray maximizes the contact between the gas and the slurry due to the vigorous frothing action that occurs on the tray. The absorber tray also evenly distributes the flue gas flow across the absorber cross-section, promoting optimum contact as the flue gas passes through the absorber spray levels.

Babcock Power uses CFD simulation for LPA screen design
The efficient operation of SCR units requires good ash removal systems in place to deal with large particle ash. A CFD flow simulation study like the one described in this paper can confirm that hopper design, screen choice and placement are appropriate and optimum. Through CFD simulation, we have ensured that the velocity in the economizer outlet, hopper and LPA screen region are kept as low as possible and that the chosen outlet and hopper design produces a high aerodynamic capture rate for the popcorn ash particles. For the utility boiler considered here the screen is made up of panels and based on the flow simulation results the screen panels near the top experience high velocity flue gas flow and more prone to erosion. A different material choice for these sections of the screen will ensure the screen has adequate life.

FLS semi dry scrubber meets expectations at Norwegian cement plant
To comply with the Gothenburg Protocol, a FLSmidth gas suspension absorber, FLS-GSA® semi-dry scrubber was installed as an alternative to a more expensive wet scrubber at Norcem AS, Brevik cement plant in Norway. The F.L. Smidth semi-dry scrubber system installed at the Brevik plant has exceeded its designed performance, achieving 97.3% reduction of SO2 emissions and 95.2% reduction of HCl emissions. It has proven that it can achieve reductions in SO2 and HCl emissions that are similar to what can be achieved in a more expensive wet scrubber system. Emissions testing has shown that semi-dry scrubber system also gives the plant the capability to reduce mercury (Hg) emissions by 90%. To achieve this Mercury reduction on a long-term basis, the plant would only need to start shuttling dust from the semi-dry scrubber system to the finish mill.

5-year bag life for Dry scrubber with PPS/P84 bags.
A Czech coal burning power plant is provided with a fluidised bed boiler, a dry scrubber with calcium hydroxide as a reagent and a bag house. The baghouse is a pulse jet design with 550,000 aM3/hr capacity. The initial set of filter bags was based on a 100 % PPS material. The bags failed on high-pressure drop caused by filter material blinding. It was decided to replace these bags with bags based on a PPS/P84 blended fibres in order to improve the filtration efficiency and prevent the dust penetration into the cross section of the material. F i g u r e 9 shows the condition of the needle felt before the replacement was required and the condition of the new PPS/P84 filter media with a well-defined dust cake and no dust penetration. This bag house is achieving more than five years of bag life operation.

Valmet uses the condensing scrubber technology to recover heat
Valmet wll be an exhibitor at Sox-Nox India. It has a unique approach to recover heat. There is a lot of energy in flue gas due to the water (30–60%) contained in the fuel and steamed in the boiler. This energy escapes into the environment when the water is not condensed back into a liquid. With Valmet’s advanced flue gas condensing technology, a plant can recover this energy and use it, for example, • to increase district heat capacity • save fuel • increase the overall balance while heating up the turbine condensate. Valmet offers two technologies for heat recovery • the tube condenser • the condensing scrubber • and a combination of these two (a pre-scrubber and a tube condenser).

Power Plant high pressure isolation valve choices
Considering isolation valves on the higher pressure systems (HP) essentially there are two choices. The first one, the wedge gate valve, has risen in popularity due to the drive to reduce costs. It offers a ‘one time’ sealing solution due to the wedging action between the plug and the seat. However, these valves should be avoided on steam plants where temperature changes potentially result in thermal binding of the wedge and locking of the valve in the closed position. The best solution for power plants is the parallel slide valve, invented by Hopkinson in 1881. Compared to the wedge gate valve; all the components in a parallel slide valve are free to move no matter what the temperature. This means that, as the valve heats and cools, seat integrity is maintained without any thermal locking. The valve has a rising stem but, unlike the wedge gate valve, it is positioned seated, meaning there is no additional force required to seat or un-seat the valve.

At Turow, Poland Derakane replaces borosilicate glass
The FGD (Flue gas desulfurization) unit operates at a temperature of 160 F (70C) under normal conditions. However, during the construction period, two of the four units were not operative and ran in the bypass mode. During the by-pass operation one of the units ran for two years at temperatures up to 320F (160 C). The previous chimney liners were constructed of borosilicate blocks which needed to be replaced due to the wet circumstances and the huge swings in temperature 70 – 320 F (20 – 160 C). Each of the four units consisted of a chimney liner 17 feet (5.3 m) in diameter and 395 feet (120 m) tall. In addition, there was a total of 1100 feet (330 m) of ductwork with the same diameter. FRP fabricated with Derakane 470HT was selected for this project due to its chemical resistance to the wet flue gas and its ability to manage the huge swings in temperature up to and beyond 320F (160 C).

Laboratorial scale experiments were conducted to investigate a novel system integrating catalytic ultrasound oxidation (CUO) with membrane bioreactor (CUO-MBR) on advanced treatment of biologically pretreated coal gasification wastewater. Results indicated that CUO with catalyst of FeOx/SBAC (sewage sludge based activated carbon (SBAC) which loaded Fe oxides) represented high efficiencies in eliminating TOC as well as improving the biodegradability. The integrated CUO-MBR system with low energy intensity and high frequency was more effective in eliminating COD, BOD5, TOC and reducing transmembrane pressure than either conventional MBR or ultrasound oxidation integrated MBR. The enhanced hydroxyl radical oxidation, facilitation of substrate diffusion and improvement of cell enzyme secretion were the mechanisms for CUO-MBR performance. Therefore, the integrated CUO-MBR was the promising technology for advanced treatment in engineering applications.

Analysis by HT allows plant to better understand optimum operating mode for BCP
Hayward Tyler was contracted by a major Engineering, Procure and Construction (EPC) company to assess the expected degradation to a BCP based upon 22 different plant operating conditions. The operating conditions varied from cold starts/stops to hot start/stops and trip conditions. HT carried out thermal stress analysis and fatigue life calculations using Finite Element Analysis (FEA) to quantify the degradation expected on the BCP. This included assessing for component interference due to rapid thermal expansion and a calculated fatigue life of the main components due to thermal shocking. The results showed that all operating scenarios would be acceptable except one, which would result in a mechanical rub between the impeller and diffuser wear rings. This scenario could cause significant damage to the BCP if it is was undertaken by the plant. In addition, Hayward Tyler was able to identify the highest stressed areas of the pump case based on the FEA results. This can be used when carrying out local inspection of the pump case. The analysis allows plant operators/owners to better understand the damage to their equipment based on how they want and need to operate the power plant. They are able to make informed decisions on operating regimes by understanding the impact to their BCP.

Older review of India particulate and FGD options
This article is several years old but has some current value. Precip upgrades are needed. For example; NTPC Rihand, whose performance is good (gross efficiency of 36 per cent), is upgrading its 25-year-old ESP to meet PM norms of 50 mg/ Nm3. It is installing advanced moving electrode electrostatic precipitator technology in two fields (the remaining four fields in the middle will remain fixed-electrode type) of the ESP. This technology is expected to reduce emissions from around 400-500 mg/ Nm3 to 50 mg/ Nm3. Relative to FGD Major power equipment manufacturing firms have signed patent agreements for SO2 emission control technologies. Thermax has signed partnership with Marsulex, ISGEC Heavy Engineering Company Pvt Ltd with Amec Foster Wheeler, and Bharat Heavy Electricals Ltd.

The market in the U.S. for biomass as an alternative fuel to coal has previously been limited due to its classification as a conventional fuel. However if biomass is considered to be carbon neutral status, coal-to-biomass conversions can offer a number of benefits under the right circumstances. Those include a low-cost solution to plant life extension, significant reductions in emissions and a cost-effective solution to increase a utility's renewable energy portfolio. This article is by Robert Broglio, Director Sales for Doosan Power Services, America The different ash characteristics (compared to bituminous coals) and the low sulphur content associated with biomass fuels means that the performance of flue gas dust removal equipment, principally electrostatic precipitators, should be carefully considered. Minor modifications and changes to operating practices may be appropriate.

South Korean power plant switches to biomass and upgrades precipitator
The potential for classification of biomass as a carbon neutral fuel provides utilities with the opportunity to economically lowering their CO2 footprint and improving emissions compliance by re-purposing aging coal fired assets. The conversion of coal fired plant to co-fire or to fire 100 percent biomass can be considered as a mature and proven technology which can readily be implemented while retaining fuel flexibility to meet future changes in environmental regulations and market conditions. In Europe and in many other parts of the world biomass is already playing a significant part in the drive to utilise an ever-greater proportion of renewable energy in electricity production. It is hoped that the current direction of the EPA towards a carbon neutral classification for biomass, as evidenced by its recent ruling, is a major step towards stimulating a similar trend in the USA. Dave Wilson is operation manager for Doosan Power Services. Mark Upton, a specialist engineer in boiler design+development at Doosan Babcock described the Yeongdong Power plant conversion in South Korea which included a precipitator upgrade.

High Chlorine coals are less costly and can create a byproduct
The advantages of using high chlorine coals are the lower cost and the ability to produce a byproduct. This article points out that Illinois coals with 0.2% chlorine content are being burned in many units without extreme corrosion. In fact, it is hard to draw a direct correlation between corrosion and chlorine content. Some coals with 0.3 % coal are being successfully utilized. The conclusion is that there are multiple factors creating the corrosion. Steps such as more even fuel combustion can be more important than chlorine content.

Risk analysis to be implemented for refinery ESPs
On February 18, 2015, an explosion occurred in the ExxonMobil Torrance, California refinery’s Electrostatic Precipitator (ESP); a pollution control device in the fluid catalytic cracking (FCC) unit that removes catalyst particles using charged plates that produce sparks during normal operation. The incident occurred when ExxonMobil was attempting to isolate equipment for maintenance while the unit was in an idle mode of operation. Preparations for the maintenance activity caused a pressure deviation that allowed hydrocarbons to backflow through the process and ignite in the ESP. The U.S. Chemical Safety and Hazard Investigation Board (CSB) identified several process safety design weaknesses in the Torrance refinery FCC unit at the time of the incident. As a result, the CSB made four recommendations to Torrance Refining Company LLC. This recommendation is specific to requiring a siting risk analysis be performed of all ESPs and the implementation of appropriate safeguards.

Thermax supplies power plants for waste fuels
Thermax has designed a boiler that will generate steam and power using highly polluting distillery waste – spent wash – as fuel. The first such boiler was supplied to a distillery in Karnataka. Distilleries can be highly polluting as 88% of their raw materials result in waste, which is discharged into fields and water bodies. Spent wash is one of the polluting byproducts of the distilling process in molasses-based plants. This brownish liquid waste is spewed out in large quantities; a typical distillery generates about 1,000t every day. Earlier, this waste used to be treated by bio-methanation (producing biogas to be used as fuel in boilers) or converted to manure through bio composting. However, both methods have their drawbacks. Large quantities of waste still remain after biogas production, posing a serious threat to local water bodies; and bio-composting is hampered by the requirement of large tracts of land and by rains that spread pollution. Although Thermax has extensive experience in burning a wide array of waste fuels, spent wash brought its unique set of vexing problems for the boiler and heater group. Besides the high moisture content, spent wash is highly corrosive and contains melting material that makes combustion difficult. These issues were sorted out after extensive R&D trials, and with coal as a support fuel, the 23 TPH Thermax boiler successfully incinerates the spent wash at the Karnataka distillery. An evaporator concentrates the 1,000t waste to around 200t before it is fed into the boiler. Steam from the boiler is used in the distillery processes and also co-generates 2MW of power. This ended its dependence on the power grid.

Dense slurry key to ZLD at Hungarian Power Plant
The U.S. Environmental Protection Agency identified biological treatment as the baseline treatment technology for FGD wastewater in the ELGs. However, it is becoming evident that bioreactors exhibit high capital and operating costs, occupy significant space, and are sensitive to changes in temperature and pH. Dense slurry ash management can sequester large quantities of FGD wastewater along with the contained contaminants through hydration, encapsulation, and entrainment for a fraction of the cost of traditional treatment. By using dense slurry sequestration of FGD wastewater, off-site discharge of effluent can be avoided altogether. Dense slurry was employed at (among other plants) the Matra Power Plant near Budapest, Hungary, and this technology played a key role in helping the plant achieve zero liquid discharge (ZLD). The Matra project is summarized and data are presented that show how the technology helped the plant achieve ZLD and other environmental objectives.

China developing new flyash uses as building industry slows
China’s coal-fired power plants produce about 600 million tons fly ash annually, which has caused severe economic and environmental problems. This paper first describes briefly the production and utilization status of coal fly ash in China. Then it analyzes the main challenges to the fly ash utilization in China due to the conflict between the huge amount of production of fly ash and the depressed consumption of fly ash, as well as the increasing driving forces in environmental protection. Subsequently, the new developments of fly ash utilization in China, including valuable elements extraction, geopolymer production, fly ash-based ceramics synthesis and soil desertification control are introduced in detail. CFA can mix with cement, gypsum and clay, etc. to produce autoclaved aerated concrete blocks. Because no high temperature is required. This technique reduces air pollution and decreases energy consumption, so the above utilization ways are very popular in China.

UK is importing ash and taking global view
In 2017 the UK generated only 1 million tons of ash, recovered 0.5 million from landfills and imported 254,000 tons, so demand exceeds supply and this gap will increase with more coal plant retirements. From October 2016, the UK Quality Ash Association (UKQAA) started to accept members from overseas. As the market for quality ash continues to grow, UKQAA believes the importation of ash will have an important role to play in the future. While the main role is to protect and maintain UK production and supply, the transition away from coal-fired power over the next five years will have an impact on supply if UKQAA doesn’t intervene.

Velan was a Major Valve Supplier to Barh
The Velan order for Barh, was worth more than $20 million —it included high-pressure gate, globe, and check valves as well as steam traps and other equipment totaling approximately 4,700 items, plus spares. Six of the 20˝ forged high-pressure gate valves are motor-operated, and they’re in special F91 material for 2900 class service. The plant installed the Velan patented Ultraflex™ wedge valves, an enhanced gate valve with a flexible wedge that is particularly suitable for high-temperature, high-pressure, and severe temperature-pressure cyclic service conditions. This wedge features a novel folded topology that makes it far more flexible than earlier flexible wedge designs of similar proportions, without weakening the wedge blades and detracting from its pressure-retaining function. Velan has supplied the valves to the Russian boiler manufacturer for use in the three 660 megawatt units at Barh.

Wilo Cooling Water Pumps have proved their value at Inner Mongolia Power Station
The ‘Inner Mongolia Shangdu’ power station is one of the main suppliers of electricity for northern China, with capacity of 8 x 600 MW. In its first two years of operation, the power station produced 1.58 billion kWh of electricity. Further plans included an intermediate pumping station between the Luan River and the Shangdu power station. Building such an intermediate pumping station in the grass savannah would have incurred significant additional costs, particularly in winter and in terms of road construction costs, etc. Therefore, Wilo produced an alternative solution to render the project more cost-effective and resource efficient. Five bronze-version water purification units were installed at the Chinese power station. These units had been in operation since 2005 in a water supply pumping station in Inner Mongolia. Since their installation, they have supplied the Shangdu/Neimengu power station with cooling water without any malfunctions. To do so, the pumps extract cooling water at 4 – 10 °C from a reservoir and transport it 35 km miles through pressure pipes (DN 400 – DN 1000) to an intermediate pumping station situated on a hill. From there, the cooling water flows another 35 km through another pressure pipe to the power station.

SEFA upgrades flyash and eliminates an environmental challenge
SEFA has successfully demonstrated the viability of STAR® Technology through commercialization at three STAR® facilities. The most recent STAR® Plant at the Winyah Power Station has the ability to process 100% ash reclaimed from ponds. The waste heat generated from the STAR® Process is used to dry the pond ash thus making the entire plant a self-sustaining closed loop system. Further, the plant can switch at a moment’s notice from the reclaimed ash to 100% dry ash produced at the power plant, or any blend of both. This flexibility allows full load operation at all times without any dependence on operation of the power generation plant now or in the future. This unique independence is particularly important as the supply of fly ash for the construction industry continues to dwindle as more coal fired generation is taken off line. At the same time the market for high quality fly ash continues to grow. Utilizing reclaimed ash from ponds and landfills will provided continuous feed material and ensures uninterrupted supply for customers.

Coal fired power in the U.S. and Europe shaped by regulations
Tony Licata provided a good summary of the impact of environmental regulations on coal fired power. He observes that the economic pressures of compliance with the MATS rule and the price of natural gas available for power generation have directly resulted in the closure of more than 30 GW of coal-fired capacity. As a result, there have been regional shortages of fly ash sold to the cement industry. This shortage has caused fly ash to be imported from China in some cases. However, certain high-uranium coal deposits in China produce fly ash that is too radioactive for reuse.

Wet FGD: Most Profitable Markets
Wet calcium based FGD systems treat more hot gas than all the other air pollution acid gas removal systems combined. There are 2 million MW of installed systems. These systems clean 7 billion cubic feet per minute of exhaust gas. The average installed cost was $200,000/MW resulting in a cumulative investment of over $400 billion. The O&M, consumables and replacement market exceeds $50 billion per year. The capacity growth rate has slowed to 1%/yr. This is due to a combination of 1% retirements in the West, more than offset by a 2% growth rate of new plants in Asia and elsewhere. New construction is averaging 30,000 MW per year. The market will grow over the next 10 years regardless of greenhouse gas initiatives. Some countries in Asia with indigenous coal and no natural gas have no other choice than to install coal-fired power plants if they want to grow their economies in the next decade.

United States Imports and Exports are significant portions of Apparent Consumption. Magnesia markets tend to be worldwide. China in particular is a major producer and consumer of magnesia products. USGS Data show that China has exported large quantities of magnesium oxide (MgO) to the United States. Magnesia is used in several Markets, and global supply and demand is driven by global product requirements in those markets. Events in China since 2016 have reduced both imports and exports to China. Martin Marietta Magnesia Specialties is vertically integrated. This means an unusual level of control over raw materials such as dolomitic lime from its plant in Woodville OH.

Wet booster fans evaporate small droplets leaving the FGD scrubber
Alden Research Laboratory performed a study in 2012 into the environmental benefits of using wet booster fans, considering that these heat up the treated flue gas by 3 to 5 degrees C. The study included both thermodynamic calculations and physical tests using a laboratory scale model. The study showed that, at nominal unit load, (a) the booster fans will have the capacity to evaporate small diameter droplets contained in the wet gas including all of the water from the fan wash cycle and (b) raise the flue gas temperature sufficiently to enable the thermally insulated, Pennguard lined chimneys to maintain the flue gas temperature just above the water dewpoint, effectively eliminating condensate formation in the wet stacks. A properly designed liquid collection system in the outlet ducts and the chimney breeching will still be needed, to collect bigger droplets that may not have enough time to evaporate.

This study by Sargent & Lundy provides methods to determine costs of DSI for acid gas removal. The sorbent requirement is a function of particle size, particulate control device, and other factors. 2016 cost factors are utilized. Based on commercial testing, removal efficiencies with DSI are limited by the particulate capture device employed. Trona, when captured in an ESP, typically removes 40 to 50% of SO2 without an increase in particulate emissions, whereas hydrated lime may remove an even lower percentage of SO2. A baghouse used with sodium-based sorbents generally achieves a higher SO2 removal efficiency (70 to 90%) than that of an ESP. DSI technology, however, should not be applied to fuels with sulfur content greater than 2 lb SO2/MMBtu.

IAC rebuild of RA filter system for coal fired boiler
IAC evaluated a baghouse rebuild project to review a 16-module reverse air structural baghouse. The original scope of the inspection was to evaluate the baghouse for needed repairs due to concerns over corrosion that had taken place over the years, as well as overall baghouse performance. This baghouse collects fly ash off of the plant's coal-fired boilers, which are used to generate steam for the needs of the plant. A detailed inspection report was generated and sent to the customer. The report included a list of recommendations for a scope of repair work. A substantial portion of these recommendations included the replacement of numerous dampers on the baghouse, as well as the reverse air ductwork. Follow-up meetings were held at the plant to discuss various option for upgrading the baghouse equipment or possible converting it to a pulse-jet. The customer reviewed our recommendations and focused on the damper and duct repair as items to get approved for a baghouse rebuild project. Several months of internal discussions within the plant took place to further define the project. IAC provided budgetary equipment and labor pricing. IAC went through the documentation process with the customer to become an official “approved contractor”. The insurance and safety requirements were substantial. IAC was certified as an approved contractor. IAC provided all supervision, safety management, labor, tools, crane, forklifts, scaffolding, and materials. IAC's wholly-owned construction subsidiary, Adelphi Construction LC, provided all project installation manpower, including project manager, shift supervisors, safety manager, foreman, welders, pipefitters, rigger, firewatch, helpers, and confined space attendants.

$6 Billion Market for NOx Control Consumables
In 2019 stationary sources will spend $2 billion for catalysts and $4 billion for treatment chemicals to reduce NOx. This is the latest forecast in N035 NOx Control World Market. The largest purchasing segment will be coal fired boilers. This segment is shifting geographically as India is retrofitting a number of its boilers. The retrofit market in China has leveled off since a very large catalyst manufacturing industry was created. The U.S. coal fired NOx market will remain flat. The EU will show a modest gain. Stricter EU-wide standards for emissions of nitrogen oxides (NOx) will have to be met by 2021. Other markets are smaller than the coal fired power market. The gas turbine market continues to grow. This includes oxidation catalysts as well as SCR catalysts. Waste to energy plants are being built everywhere but the U.S. There are various requirements for Nox control in most industries with combustion processes. There are a number of catalyst suppliers. Improvements in technology include the combination oxidation and SCR catalyst supplied by Cormetech. The catalytic filter is a new development which could substantially affect the market. Dürr supplies Catalytic Candle Filters (CCF). The catalytically coated filter candles can withstand temperatures of up to 716° F, simultaneously remove dust, sulfur dioxides (Sox), and nitrogen dioxides (Nox) from the exhaust air. A number of biomass and glass plants have incorporated this technology in Europe and the U.S. Glass producer Libbey is the first manufacturer to use the new exhaust air purification technology in its plant in Beijing. There are a few major companies providing the Nox reagents. Yara is unusual in that it supplies SNCR systems as well as reagents. Yara is one of the largest producers in the world of ammonia and urea, with one third of the ammonia traded in the world being supplied by Yara. The company ships ammonia and urea around the world to SCR and SNCR customers via a network of 30 plants and 200 terminals and warehouses.

Constellation Energy’s 340-MW Wagner Unit 3 with SCR, tubular air preheater and cold side ESP and 130-MW Unit 2 with Ljungstrom air preheater and cold side ESP participated in Solvay Chemicals testing of Trona and sodium bicarbonate injection for SO2, SO3, NOx and mercury reduction. Industrial Accessories Company (IAC) provided the rigs, injection lances and test management. The required SO2 removal rate was 30 to 50 percent. Both units use activated carbon (PAC) injection for mercury control. The units fire CAPP coal (0.83 percent sulfur) or a blend of CAPP and PRB. Youngen Kong and Stan Carpenter of Solvay Chemicals, Salil Bose and Matthew McMillian of Constellation Energy, and Pramodh Nijhawan of IAC reported at Power-Gen International 2009 that Trona was able to meet the SO2 removal targets for various fuel types at feed rates between 1.1 and 2 NSR. A higher SO2 removal rate was obtained with sodium bicarbonate. ESP performance was enhanced by Trona (with no PAC injection) and NSR 1.1, which reduces SO2 by 29 percent. Around 10 percent NOx was also removed (a bonus) with both sorbents. For Unit 2, mercury removal increased from 82 to 90 percent with Trona injection alone (NSR 1.1). For Unit 3, up to 80 percent of the mercury was removed by PAC without Trona. Over 90 percent mercury removal was realized by PAC with Trona injection (NSR=0.1). The positive effect of sodium bicarbonate on mercury removal was also demonstrated and is comparable to Trona.

Dynegy SDA installation at Baldwin is permitted for new wastewater discharges
The subject facility has applied for a renewed NPDES permit which includes modifications that necessitate an antidegradation assessment. New wastewater discharges will be created as the result of the construction and operation of new dry flue gas desulfurization systems (Spray Dryer Absorbers or SDAs) at all three units at the complex. The installation of these systems was required by the terms and conditions of a 2005 Consent Decree between Dynegy, the state of Illinois, USEPA, and the U.S. Department of Justice. Construction of the Unit 3 SDA system and baghouse has been completed and they were put into service prior to December 31, 2010. The Unit 1 SDA system and baghouse were placed into service by December 31, 2011. The Unit 2 SDA system and baghouse were placed into service by December 31, 2012. The new discharges from these systems would consist of sump discharges, air compressor noncontact cooling waters, and miscellaneous floor and storm drainage waters. Dynegy is requesting authorization to discharge these wastewaters to the existing bottom ash pond system and include these discharges as contributory wastewater streams to Outfall 001. Sump discharges are not expected to occur more than once per week with each discharge lasting approximately five minutes. Based on the current operation of the Unit 3 sumps (projected discharge of 0.127 MG/year), it is expected that sump discharges for all units would contribute 0.38 MG/year of flow to the ash pond. Air compressor noncontact cooling waters from the new SDA systems (6.5 MGD) and miscellaneous floor and storm drainage waters would be received by the cooling pond and would be potentially discharged from Outfall 002 during overflow conditions

IAC evaluated a baghouse rebuild project to review a 16-module reverse air structural baghouse. The original scope of the inspection was to evaluate the baghouse for needed repairs due to concerns over corrosion that had taken place over the years, as well as overall baghouse performance. This baghouse collects fly ash off of the plant’s coal-fired boilers, which are used to generate steam for the needs of the plant. A detailed inspection report was generated and sent to the customer. The report included a list of recommendations for a scope of repair work. A substantial portion of these recommendations included the replacement of numerous dampers on the baghouse, as well as the reverse air ductwork. Follow-up meetings were held at the plant to discuss various options for upgrading the baghouse equipment or possibly converting it to a pulse-jet.

Aggreko mobile gas generators for power in the Permian basin sand plants
One of the largest hurdles miners face is limited access to interconnected power grids, commonly found in remote areas such as West Texas where none exists. Seeking a solution to this problem, many mining companies are turning to mobile natural gas power generation. The use of natural gas power equipment provides significant benefits allowing mining companies to get online quicker and reduce lead time from the feasibility stage to production in remote mining locations where utility power sources are unavailable. In the Permian, one regional frac sand provider built two new mines but faced a challenge bringing both online when the build would be ready long before utilities would be available in the area. The sand producer met with a third-party provider of mobile power generation and was provided with a project specific engineered plan, operations management, technical expertise and 24/7 remote monitoring. Using natural gas generators, 14 MW of power was deployed at each site, utilizing compressed natural gas (CNG) for two weeks until pipeline gas infrastructure was available. Electrical distribution equipment and dedicated, certified technicians were also provided to both sites. The natural gas system provided cleaner emissions and reduced power costs by 40% compared to diesel. And 24/7 remote monitoring ensured the frac sand operator had full visibility and status reporting on the power system, plus maximized uptime.

High efficiency biomass CFB boilers for the Asian market
This paper presents the design aspects of CFB boilers, co-fired with biomasses, by considering the selection of steam conditions, process design and specifics of boiler auxiliary equipment selection, as well as, the emissions control systems for those biomass co-firing applications. In this context, the experience with CFB boilers working with high steam conditions was presented Doosan Lentjes delivered cutting-edge CFB technology and flue gas cleaning (FGC) technology at the Provence CFB Power Station in Gardanne, France. Doosan Lentjes work formed part of a comprehensive coal-to-biomass conversion. This approach contributes to owner commitment to clean, high performance energy production, and is expected to reduce their CO2 balance by 600.000 tons per year. This CFB concept itself proved to sufficiently fulfil typical requirements on gaseous emissions without additional flue gas cleaning equipment (except bag house or ESP). Nevertheless, just in case due to specific local regulation very low emission limits are set up, the plant layout can be easily added by optional SNCR or SCR and lime or sodium bicarbonate powder injection to further reduce the low raw gas emissions of the biomass CFB combustion to figures of below 50 mg/Nm3

Doosan Lentjes super critical 300 MW CFB for low grade coals
In cooperation with its parent company DHI and supported by Doosan Babcock, Doosan Lentjes has developed a reference design for a 300 MW class SC-CFB boiler utilizing low grade coal. The activities have been backed by CFD analysis and physical model testing. The proven pantleg design, an opposed arrangement of 2x2 cyclones and integrated FBHE’s are the main features of the combustor. The flue gas leaving the cyclones enters into a cross-over duct leading to the inlet of the convective pass. The convective pass accommodates most of the heating surfaces. Due to the elevated steam temperatures it has become necessary to arrange a pendent type superheater in the upper part of the combustor. Coal and limestone are fed on the circulated ash flow and enters via 2x4 ducts into the combustor. Flue gas, primary and secondary air system has been designed according to a 2x 60 % approach thus enabling part load operation in case of unavailability of one fan or one rotary air preheater.

PTFE Membrane development by Idex reduces metering pump total cost of ownership
Through extensive research and development, IDEX has designed a new PTFE diaphragm featuring a unique chemical composition of PTFE that offers the best of both worlds—combining the benefits of PTFE with the temperature and high-pressure resistance of metallic diaphragms. The result is a smaller, lighter and less expensive pump suitable for the widest range of metering pump applications—from chemical manufacturing to refining to power generation to offshore oil and gas production, and for all forms of water and wastewater treatment.

Disinfection, pH adjustment are ways to facilitate greater water reuse in power plants
The effective management of water and wastewater investments can save power plants 1 to 2 percent annually, which adds up to millions of dollars each year. While these benefits may never equal the financial advantages of once-through cooling processes, they do enable power plants to use significantly less water. The criteria for selecting metering pumps typically includes flow rates, pressures and corrosion resistance (depending on what chemicals are pumped). Although plant operators and the engineering, procurement and construction (EPC) firms that serve them have multiple options for pumping infrastructure, the most popular choices usually involve diaphragm or rotary gear pumps.

Water treatment and cooling applications for power plants
Plant operators need a durable pump technology that is able to dose a precise volume of water treatment chemical, while maintaining a high level of operational reliability. This is one reason why hydraulic diaphragm metering pumps are preferred for a majority of water treatment applications in power plants. The pump’s ability to survive system upset conditions helps keep the overall plant infrastructure operating reliably, all while dosing the exact amount of chemical needed to keep operations running efficiently. Space in any plant is valuable, so operators prefer pumps with small footprints. Disinfection - is accomplished by dosing specific quantities of high-concentration sodium hypochlorite (bleach). When sodium hypochlorite comes in contact with bacteria, it oxidizes molecules in the cells of the germs and kills them. Even though this simple but harsh chemical has been used for more than a hundred years, it is prone to causing problems for pumps by “offgassing.” To solve this issue, the pumps used to deliver it must be able to pass the gas bubbles through without locking or clogging the pump.

Chemical companies can reduce total cost of ownership with the right mix of metering pumps
The four most common chemical metering pump applications in chemical manufacturing plants include: • Dosing precise volumes of chemicals to make products • Pretreating the process water to boost quality and efficiency • Dosing antiscaling chemicals to clean and protect plant infrastructure • Post-treatment of the wastewater prior to disposal. Each of these applications can be addressed by reciprocating pumps, which work by using a piston or a diaphragm to dose a precise volume of fluid with each stroke. Reciprocating pumps are highly engineered to provide extreme accuracy at high pressures and relatively low flows. Rotary gear pumps provide a cost-effective alternative for some applications. They work by moving fluid in a circular fashion between gears. Rotary pumps pick up fluid at the suction port between the gear teeth, and they carry the fluid around the outer diameter of the gears to the discharge port. Rotary pumps are best utilized in high-volume, low-pressure applications, and their flow rates can be controlled with variable speed drives. Each pump type has advantages, and they both come at different price points. By incorporating the right mix of chemical metering pumps, DowDuPont, BASF and other chemical companies have been able to save money without compromising on performance.

Reliability – Chemicals such as sodium hypochlorite tend to off-gas when they come in contact with metal surfaces. However, non-metallic gear pumps feature a simple design that helps prevent off-gasing, which minimizes disruptions and helps to maximize uptime for water treatment operations. Safety - Because exposure to chemicals such as chlorine gas can cause respiratory issues for employees, great care should be taken to ensure that leaks do not occur when dosing hazardous chemicals. Sealless gear pumps offer fewer points of failure because there are no leak points for harsh chemicals to damage the pump or the surrounding equipment. Streamlined Maintenance – Easy access to the inner workings of a gear pump enables it to be maintained in place, which minimizes downtime by eliminating the need to lock out/tag out the pump and move it to the repair shop. The simpler the design is, the easier the pump is to maintain. This gives plant operators greater flexibility to schedule maintenance between shifts, or whenever it is least disruptive to do so. Smaller Footprint – Rotary gear pumps are compact in nature and they don’t require as many ancillary items as diaphragm pumps do (such as pulsation dampeners), so the overall size of the equipment package can be reduced.

RCEP Will Be the Biggest Power Plant Pump Market
The Trans-Pacific Partnership (TPP), which has been renamed the Comprehensive and Progressive Agreement for the Trans-Pacific Partnership (CPTPP), is currently involved in a free trade deal known as the Regional Comprehensive Economic Partnership (RCEP). The partnership involves ten members of ASEAN and its six dialogue partners. If the deal succeeds, RCEP will become the world’s largest trading bloc, accounting for 3.4 billion people with a total Gross Domestic Product (GDP) of $49.5 trillion. It has been forecasted that the coal fired power will remain the largest purchasing segment in the world power industry over the next five years. It is not surprising, therefore, that most of the pump purchases in RCEP power plants will be for the coal fired generation. China has installed over 900,000 MW of FGD systems. Other countries in RCEP are projected to require another 400,000 MW of new and retrofit systems, which will ultimately drive the pump business further.

Power from Biomass to Grow 250% in 10 Years
Combustion of biomass poses a number of problems, particularly in utility scale boilers. The circulating fluidised bed has features that control ash agglomeration, fouling, and corrosion, and therefore make it particularly suitable for biomass applications, with inherent characteristics that favour low emissions. The technology also has considerable potential for scale up, and adoption of greatly improved steam conditions say Robert Giglio and Timo Jäntti of Sumitomo SHI FW Worldwide power generation capacity using woody biomass and agricultural biomass wastes is projected to grow by a factor of more than 2.5 from 2015 to 2025. Since 2008, over twenty 100% biomass fuelled CFB plants employing Sumitomo SHI FW technology have been commissioned. The largest operating utility scale ABC installation to date, the 205 MWe Polaniec plant of GDF Suez Energia Polska plant, located in Poland, has been in commercial operation since 2012.

MHI facilitating the opportunity to purchase CFT Products across Divisions
The company is targeting 2018 sales of $ $37 billion rising to $45 billion in 2020……. Under its “Shared Technology Framework,” MHI Group is striving to strengthen its technological and marketing infrastructures, optimize the value chain across the Group (including procurement), and reinforce the competitiveness of its businesses in the medium-to-long term. MHI Group handles a greater variety of products than its competitors, and in order to turn this product diversity into competitiveness, it is promoting group-wide technology and knowledge sharing in product development. Applying cutting-edge technology from gas turbine development to numerous other products, such as compressors, centrifugal chillers, and turbochargers, is one example of what it is doing to realize conglomerate synergies by technology and knowledge sharing. Combust, flow and treat (CFT) suppliers therefore have the opportunity to also understand the group-wide opportunities and offer packages covering the gamut of opportunities. CFT opportunities are mainly in the following two of three main divisions----- POWER SYSTEMS: Intelligent Transport Systems gas and steam power generation systems, nuclear power plant equipment (light-water reactors/nuclear fuel cycle & advanced solutions), wind power generators, aero engines, compressors, marine machinery.-------- Overview of Fiscal 2017----------- Having been hit by global market factors such as the acceleration of the shift to low-carbon approaches and the switch to renewable energy, coal-fired power plants saw a significant decline, and order volumes for gas turbine combined cycle (GTCC) systems also fell considerably. As a result, consolidated orders received decreased year on year, to ¥1,437.5 billion. Consolidated net sales rose year on year to ¥1,493.9 billion, driven by steady progress in work-related to orders for gas and steam power generations, as well as increases in aero engines. Although there were improvements in the profitability of the gas and steam power generations, aftersales service, due to such factors as the decline in nuclear power plant equipment, operating income was flat year on year at ¥108.9 billion. ------ INDUSTRIAL: Metal machinery, environmental systems, paper converting machinery, mechatronics systems, ITS, material handling equipment, engines, turbochargers, air-conditioning & refrigeration systems, automotive thermal systems, machine tools, commercial ships, transportation systems, and chemical plants.------------- In addition to increases in metals machinery on the back of strong infrastructure investment, orders grew for turbochargers, material handling equipment, air-conditioning & refrigeration systems, and other items due to economic expansion, primarily in developed countries. Consequently, consolidated orders received rose year on year to ¥1,711.3 billion. Consolidated net sales exceeded the level of the previous fiscal year and rose to ¥1,898.9 billion, driven by increases in material handling equipment and turbochargers, for which orders were strong, and in commercial ships.----- EXAMPLES of CFT OPPORTUNITIES: Flue gas desulfurization, waste-to-energy, geothermal, CO2 recovery, marine scrubbers, sinter plant waste heat recovery, gas turbine combined cycle plants, coal-fired boilers---- ENERGY EFFICIENCY: The company is focused on improving energy efficiency with data analytics and remote monitoring. It is fostering cross divisional projects.

Cement Kiln Dust for SO2 removal
From 10 to 12 million tons of cement kiln dust accumulates annually at domestic cement plants. This finely divided dust is emitted from cement kilns to prevent the buildup of excessive salts in the cement product. If separated into its valuable components, waste cement kiln dust could become a significant source of potassium and a raw material for making cement. This article does not include the use of this dust for SO2 removal from coal-fired boilers, but potassium is very reactive and would be a good reagent. One question is its use in direct sorbent injection or DSI. There is widespread use of drinking water plant lime sludge as an FGD reagent. So other alternatives should also be explored. The use would be primarily where a small boiler is near a source or where multiple sources can be included so that enough reagent for a large application is available.

Biological Treatment or ZLD for FGD Wastewater
The Biological treatment process is perceived as the low-cost option to FGD treatment and the Zero Liquid Discharge process is perceived to be more expensive from a CAPEX and OPEX standpoint. While this is true, the difference is not as much as has been presented within the market by various engineering firms. In addition, there are options for achieving ZLD while reducing the costs associated with this alternative. Burns & McDonnell has postulated that the cost of biological treatment plants and ZLD plants are closely competitive up to 200 GPM whereas CH2M indicates the installed cost of ZLD to be three times that of Biological treatment. The equipment costs and estimated installation costs of the ZLD system generated by Aquatech paint a much more positive depiction of the relative installed costs of ZLD compared to Biological treatment.

Advanced Process Control for optimizing Flue Gas Desulfurization
Yokogawa is improving plant efficiency by reducing pump horsepower while maintaining needed SO2 removal. The optimization system typically consists of three functions: enhanced regulatory control, model-based prediction, and process value prediction. The system uses these three functions to continuously determine the minimum required number of recirculation pumps in operation, and to calculate the setpoint for the limestone slurry flow PID (proportional-integral-derivative) control loop……………... Enhanced regulatory control governs the number of recirculation pumps in operation and calculates the slurry flow setpoint. It also calculates the optimal pH setpoint, using feed-forward control for some abnormal cases. Enhanced regulatory control also keeps track of the run time of each recirculation pump, and uses this data to equalize the operating times of the pumps.……………... This optimization system automatically adjusts to different coal types because it uses the inlet SO2 value as an input to the system. This value varies significantly based on the coal type and is an important parameter for optimizing control. The system also automatically adjusts for spray nozzle plugging and pump performance deterioration. Varying plant load is not a problem as the optimization system works well in the range from low to full load.……………... A 700-MW coal-fired power plant in Japan implemented the optimization system described above. This plant runs about 300 days per year at baseload, and is not in operation for the other 65 days of the year. The energy savings realized by running only the required number of recirculation pumps was 12.4% of the unit’s total house load, equating to about $900,000 in energy savings per year based on market conditions in Japan. Another benefit was reduced pump run times, which resulted in lower pump maintenance costs and extended pump life. A third benefit was less limestone usage.………………

Improving Plant Efficiency with Pump Performance and Condition Monitoring
Studies show pumps tend to be some of the more maintenance-intensive equipment in a plant, suffering a failure or some level of degraded operation on average every 12 months. Pumps in especially critical situations often have duplex and even triplex installations as backups, ready to switch over at a moment’s notice, such is their importance. Reactive maintenance, where it is necessary to fix something that has failed, costs 50% more than practicing predictive maintenance where problems can be detected and resolved before a failure. Pumps can be equipped with sensors to monitor condition and performance to ensure problems are detected as soon as possible so appropriate action can be taken…………... Over the last few years, the number of devices designed for equipment monitoring capable of operating on wireless networks has grown substantially. Some communicate using a plant’s Wi-Fi network, but a larger group has been designed to communicate via WirelessHART, the same network used by many types of wireless field instruments (Figure 2). The variety of low-power and low-bandwidth devices designed for these networks has grown enormously, and for all practical purposes, every type of monitoring device necessary for a full pump monitoring setup is available for use with WirelessHART networks.…………... Apps make it simple to perform real-time asset monitoring of a pump installation by identifying abnormal situations as they develop. Pre-packaged analytics evaluate health against unit history and industry norms, and the information is displayed via intuitive dashboards. All of this is possible with minimal configuration effort and no additional loading on the existing automation system. If desired, reporting and alarming functions can be added to external systems, but this is entirely optional.…………... New apps are available for health monitoring in conjunction with the wireless instrumentation, independent of the plant’s real-time automation system. These apps are easy to use because each is configured for a specific type of asset. Just as there are apps for pump monitoring, there are corresponding apps for other types of assets such as steam traps, heat exchangers, cooling towers, pressure relief devices, and more. This specialization helps deliver sophisticated analytics without having to create customized programming. The customization is already built into the platform, supporting fast implementation.……………

Advanced Sensors for Power Plant Instruments
Mettler Toledo is offering pH and other instruments with advanced digital sensors that go well beyond basic measurement and digital signal conversion within the sensor. Such sensors fully exploit the opportunities available when measurements are made right next to the sensor element. They don’t compromise the measuring circuit design in order to accommodate the resistance and capacitance of long analog signal cables, especially for conductivity measurement. They don’t incur uncertainty when different measuring circuits are used to calibrate the sensor than are used in the final installation because the measuring circuit is inseparable from the sensor elements. In addition, they always utilize correct calibration data for their measurements because on-board memory retains it. Advanced digital sensors include real-time predictive diagnostics. These take the sensor’s cumulative operating exposure into account to forecast in real time when calibration, maintenance and replacement will be needed. Taken together, the sum of these advanced sensor capabilities are designated Intelligent Sensor Management or ISM®. ISM sensors are able to warn of the need for service before loss of accuracy or failure, making the measurements more reliable and increasing the efficiency of maintenance scheduling. They can also eliminate unnecessary servicing

Maintaining High Combined Cycle HRSG Efficiency and Reliability
This article in Power Engineering by Brad Buecker of Kiewit addresses chemical treatment of HRSG feedwater. During the heyday of coal-fired power plant construction and operation in the last century, many lessons were learned regarding correct water/steam chemistry control in high-pressure, fossil-fuel steam generators. Even seemingly minor issues had the potential to cause serious problems, and some corrosion-induced failures led to injuries and death of plant personnel. Progress in transferring these lessons to the combined cycle power industry has often been slow, and a number of outdated chemistry concepts continue to appear in the specifications for new combined cycle plants. Some problems are magnified by the unique geometrical features of heat recovery steam generators (HRSGs) as compared to their coal unit counterparts. This article will examine three of the most important issues in this regard, as outlined below: • Unless the condensate/feedwater system of the HRSG contains copper alloys (very rare), an oxygen scavenger should not be part of the chemical treatment program. Use of oxygen scavengers, a more accurate term is reducing agent, induces flow-accelerated corrosion (FAC) of plain carbon steel. FAC has caused catastrophic piping and tube failures at a number of facilities over the last three decades, and it continues to occur at many plants. • Tri-sodium phosphate has served as the primary chemical for boiler water treatment in many base-loaded coal units, and the chemistry is often employed in HRSGs. Even at steady load, phosphate treatment is problematic due to the phenomenon known as phosphate hideout. In cycling units, hideout may make phosphate chemistry extremely difficult to control. • While a strong focus should always be placed on operating chemistry, off-line chemistry control is frequently neglected. Air in-leakage into water-filled steam generator networks during down times can significantly damage tubes, piping, turbine blades and rotors, and other equipment. Given the regular cycling nature of most power plants in today's environment, the potential for air ingress and subsequent corrosion may be extensive.

BWR auxiliary feedwater valves in OTSG
Air-operated valves LCV-4025 and LCV-4026 control steam generator level for the “A” OTSG, and LCV-4007 and LCV-4009 for the “B” OTSG. The level control system for each valve receives a level input signal from a startup range OTSG level transmitter in the essential controls and instrumentation (ECI) system. This signal is compared with a level setpoint, and the resultant error signal modulates the control valve using a proportionalplus- integral controller. Manual control is available in both the main and auxiliary control room. Parallel flowpaths (one from a motor-driven pump, one from the turbine-driven pump) and redundant instrumentation and control power supplies for the level control valves ensure flow to each OTSG. Motor-operated block valves (V-14A and V-31B in the “A” OTSG supply, V-37A and V-20B in the “B” OTSG supply) provide redundant feedwater isolation of an OTSG. The turbine-driven and motor-driven pump discharge lines combine to supply the auxiliary feed ring in each OTSG.

Electric actuators should be considered for BFR valves - Rexa
The Boiler Feedwater Recirculation (BFR) Valve, protects the plant’s investment in the boiler feedpump while still allowing the feedpump to deliver the required flow to the boiler. Depending upon plant type and design, the feedwater recirculation valve sees upstream pressure in the 2500-4500PSI range, and is responsible for taking almost a full pressure drop across the valve. Since this valve is usually closed during normal operation of the plant, the valve is typically designed for Class V shutoff, and needs to fail open on loss of power. Electric actuators have a number of advantages which have been demonstrated by a quik ROI when they replaced pneumatic actuators on this application.

Northeast coal fired power plant uses Evoqua ion exchange resins to remove vanadium from wastewater
When a coal-fired power plant in the Northeast discovered that the runoff from its ash pile contained vanadium levels exceeding discharge limits, it contacted Evoqua Water Technologies, for assistance. Test results showed ion exchange (IX) resin would remove roughly two pounds of metal for every cubic foot of resin. Calculations indicated the entire pond could be treated with less than 60 cubic feet of ion exchange media. The Evoqua’s solution featured two (2) 36” x 72” steel vessels, each containing roughly 30 cubic feet of resin. The tanks were installed in series with sampling ports after each vessel. The final effluent is sent to a holding tank for testing by a statecertified laboratory prior to discharge, to confirm that the vanadium level is within limits. When the resin in the vessels reaches capacity, the local Evoqua service branch is notified and delivers fresh tanks containing new resin to the site. Exhausted tanks are shipped to Evoqua’s RCRA-permitted treatment facility where the contaminants are removed from the resin and recycled into a raw material.

Coal analyzer at Hunter Station used to optimize coal blends
In order to estimate the ash fusion temperatures in the coal being sent to the power plant PacifiCorp Hunter Station needed an analyzer that could measure the ash constituents whose proportions determine ash fusion. The Gamma-Metrics Coal Quality Manager (CQM) analyzer from Thermo Electron Corporation provides minute-by-minute analysis of SiO2 , Al2 O3 , Fe2 O3 , CaO, TiO2 , K2 O, and Na2 O in the ash. PacifiCorp installed one of these units in its coal yard to blend coals of differing ash composition, in order to keep the blended coal’s ash softening temperature above 2175degrees F. In order to take advantage of the potential of this instrument several steps had to be taken. First the analyzer had to be rigorously calibrated and evaluated in the field to verify that the desired accuracy was achieved. Meanwhile the utility had to analyze its boiler characteristics and coal characteristics to be able to derive an ash fusion equation appropriate to the plant. Then the necessary operational steps had to be taken to ensure that source coals capable of achieving the target blend could be initially segregated and then blended at the correct ratios. After some startup difficulties, the analyzer and the blending system have been very successful in maximizing the ash softening temperatures, and the plant has substantially reduced its forced outages due to slagging while burning a variety of available fuels.

Audit by Evoqua results in power plant savings for power, chemicals and labor costs
An uninterrupted supply of high-quality water is vital to power plant operations. When making outage plans that include preventative maintenance on key plant systems, plant personnel should address the plant’s water treatment equipment, ensuring it receives the same high level of attention as its boiler, condensers, turbines and process equipment. So, how does a maintenance planner know whether the water treatment system is operating at its best and that it can meet the power plant’s current and future demands? One way is to plan an audit of the water treatment equipment before a planned outage. The audit should start with a system check-up to assess system conditions, performance and efficiencies and to pinpoint areas that need improvement. The check-up also can determine if a full system audit is required to provide a more in-depth investigation of a single or multiple water unit operation. The system audit should address the individual challenges of specific situations and include an in-plant survey and a summary of findings and recommendations for improvement.

Ovivo condensate polishing system is installed at large South African Power plant
The Eskom Medupi Power plant has installed an Ovivo Condensate Polishing Plant (CPP) at all six coal fired units. The CPP is designed to produce treated condensate with cation conductivity less than 0.1 μS/cm, chloride less than 1 μg/l (less than 1 ppb) and silica less than 5 μg/l (less than 5 ppb). The CPP treats 100 per cent of the condensate flow under normal operating conditions. This removes iron and copper corrosion products, as well as dissolved cationic and anionic impurities, while allowing ammonia ions to pass through, when operated in the ammonia cycle, maintaining a high pH to protect the condenser. The first stage of condensate polishing utilizes cartridge filters to remove most of the particulates.

PacifiCorp estimates of CCR compliance are challenged
HEAL questioned the PacifiCorp plans to meet CCR in September 2016. (See details in McIlvaine's Coal Fired Power Plant Decisions.) As of October 19, 2015, PacifiCorp had nine surface impoundments and four landfills that are subject to the CCR rule. PacifiCorp is currently in the process of closing four of the nine impoundments. *However, EPA recently vacated the provisions of its 2015 coal ash rule exempting early closure impoundments. Therefore, PacifiCorp’s four early closure impoundments will be subject to additional compliance obligations, including monitoring and possibly remediation requirements. In addition, Rocky Mountain Power has posted CCR Rule and Compliance Data and Information on its Webpage, as the EPA’s CCR rule requires. These documents outline the company’s plans with regard to the Dave Johnston, Hunter, Huntington, Jim Bridger, and Naughton power plants. While this information is helpful, HEAL says is incomplete for purposes of integrated resource planning.

2014 BHE testimony on the gas turbine, coal and geothermal projects in Utah
The purpose of Chad Teply testimony was to support the prudence of capital investments in the new Lake Side 2 combined cycle combustion turbine (“CCCT”) natural gas fueled resource, certain pollution control equipment retrofits on existing coal fueled resources, and other significant generation plant projects being placed in service during the test period in this docket, July 1, 2014 through July 2015. This included the Hayden SCR and the Blundell geothermal resource well integration project and 1 the Naughton Unit 3 natural gas conversion project. The Blundell geothermal resource well integration project integrates two 108 new geothermal resource wells into the Blundell generation system. One production well and one injection well, along with associated appurtenances, have been drilled and will be placed in service to support continued reliable electricity production at the site. Lake Side 2 is nominally rated at 548 MW base load 130 and 97 MW of duct firing for a total net capacity of 645 MW at the average 131 ambient temperate of 52 degrees Fahrenheit. Each combustion turbine exhausts 132 into its own heat recovery steam generator which then commonly supply a single 133 steam turbine generator. The electrical energy generated by Lake Side 2 will be delivered to a new 345 kV point of interconnection substation (Steel Mill) where it will tie into the PacifiCorp transmission system.

SCR and calcium bromide to be used at Jim Bridger 3 and 4
Chad Teply of BHE testified in 2012 as to the reasons SCR and CaBr2 injection were the best choice for Jim Bridger 3 & 4. The substantial capital investment was based on a retirement date of these units in 2037. The unit 3 system was to be installed in 2015 and unit 4 in 2016. The Jim Bridger Units 3 and 4 emissions control investments proposed in the Request are SCR systems and associated ancillary equipment for each unit. Each SCR system would be comprised of two separate universal reactors, with multiple catalyst levels; inlet and outlet ductwork; a shared ammonia reagent system; an economizer upgrade; structural reinforcement of the boiler and flue gas path ductwork and equipment; and extension of the existing plant distributed control system (“DCS”). An induced draft (“ID”) fan upgrade and an associated auxiliary power system variable frequency drive (“VFD”) insertion is required on Unit 4 only. Jim Bridger Units 3 and 4 it will be necessary to add a coal additive, namely calcium bromide (“CaBr2”), to oxidize mercury and then add a scrubber additive to prevent readmission of mercury in the scrubber system. The potential exists to reduce the coal additive requirements due to the SCR.

Naughton September 2016 Air Permit Application to modify H2S04 emission limit
Recent testing has demonstrated that the 0.004 lb/MMBtu emission rate is not achievable with the BACT equipment that has been installed. This permit application is to reevaluate the potential impacts of the SO3 injection system and permit an H2SO4 rate that will be achievable given the specific ambient conditions and coal characteristics that exist at the Naughton Power Plant. After evaluating the information submitted by PacifiCorp and reviewing the RBLC for similarly controlled units, the Division considers installation of alkali wet scrubbers on Units 1 and 2, meeting an emissions limit of 0.0055 lb/MMBtu, and meeting a SO3 injection limit of 4 ppmv, annual average of four (4) quarterly tests, to represent BACT for Units 1 and 2. Project emissions were estimated based on potential to emit. The new limit is in effect for PM based on MACT UUUUU requirements of 0.03 lb/MMBtu for filterable PM for EGUs, which went into effect April 16, 2015. The potential to emit for Unit 1 is based on the limit of 0.03 lb/MMBtu PM (filterable) + 0.007 lb/MMBtu PM (condensable) and the design firing rate of the unit. The potential to emit for Unit 2 is based on the limit of 0.03 lb/MMBtu PM (filterable) + 0.011 lb/MMBtu PM (condensable) and the design firing rate of the unit. Condensable is based on maximum historical condensable rate plus projected incremental increase from Hg control technology. For Unit 1, the maximum historical condensable PM emission rate was 0.0070 lb/MMBtu and the incremental condensable PM increase from the mercury control technology (calcium bromide injection – CaBr2) was projected at 0.00037 lb/MMBtu. This provides a total projected condensable PM emission rate of 0.00737 lb/MMBtu which was rounded to 0.007 lb/MMBtu in the September 22, 2015 application to permit the Unit 1 and Unit 2 H2SO4 emission limits at 0.0055 lb/MMBtu. For Unit 2, the maximum historical condensable PM emission rate was 0.0111 lb/MMbtu and the incremental condensable PM increase from the calcium bromide mercury control technology was also projected at 0.00037 lb/MMBtu. This provides a projected total condensable PM emission rate of 0.01147 lb/MMBtu which was rounded to 0.011 lb/MMBtu in the September 22, 2015 permit application. Note that the projected incremental CPM increase of 0.00037 lb/MMBtu from the CaBr2 mercury control technology was included in the December 11, 2013 application to permit the Naughton plant’s mercury control technology systems.

Wastewater permit for coal and combustion turbine plants in Gillette Wyoming
This 2015 permit authorizes the discharge of wastewater from six coal fired power plants, two combustion turbine power plants, and one coal mine. The Neil Simpson and Wygen generating power plants and the coal mine are located approximately six miles east of Gillette, Wyoming. Most of the wastewater generated by the facility is recycled, so this facility rarely discharges. Discharges usually occur in response to large storm events. Note below that the facilities are air-cooled, so they do not discharge cooling water. Therefore, 316(b) regulations do not apply. In addition, make-up water is partially treated water from the Gillette wastewater treatment plant, not waters of the Wastewater originating from the variety of sources is routed to a two cell settling pond. The first pond, called the Bottom Ash Settling Pond, functions to provide settlement for sediments and ash by-products. Wastewater from this pond overflows to the second pond called the Clear Pond. The Clear Pond has an outlet structure (Outfall 001) that allows the discharge of the treated wastewater to Donkey Creek. However, because a majority of the wastewater that enters the settling ponds is recycled, there is seldom a discharge to the creek.

Pacific Corp Naughton reduces pulverizer maintenance with new lubrication system
At the Naughton plant of Pacific Corp an advanced filtration technology for the coal pulverizer was determined to be readily available for heavy gear oil that would meet solve the maintenance problems. An off-line kidney loop filtration package using a high-efficiency, high-dirt-holding capacity, synthetic filter media was procured and installed. The package uses two filter housings mounted in series, with a common-sized element in both housings. The filter elements initially recommended for the trial installation were rated at Beta 25=200 in the first stage and Beta10=200 in the second stage. Oil flow was delivered by a vane pump rated at 10 gallons per minute for a 460 centistoke (cSt) (2,500 SUS) gear oil. Temperature ranges of the system fluid varied from a low of 65 degrees Fahrenheit (18 degrees Celsius) when idle, up to 130°F (54°C) during normal operation. The filtration package is installed with the suction line coming into the filter bank directly from the bottom of the reservoir; the outlet, or filtered discharge line, is piped directly into the top of the reservoir. The filter element condition is monitored by differential pressure gauges installed on each filter housing with a target of 25 to 28 psig as an indicator of element loading; the elements were changed out prior to allowing the internal bypass valve to begin opening. Other features of the filtration package include upstream and downstream sampling valves to allow gear oil samples to be taken without having to shut down the system.

Jim Bridger will require new pond liner
The PacifiCorp Jim Bridger Power Plant is a coal-fueled steam-electric operation with four operating units having a total generating capacity of 2.12 GW, and is located approximately nine miles northeast of Point of Rocks, Wyoming. . FGD Pond 2 is a zero discharge facility and generally evaporates water at the same rate it is disposed of in this pond. It does not have a spillway, or outlet structure. The inlet structure consists of two, 10-inch diameter HDPE pipelines which can discharge at various points along the southern side of the pond. Seepage from the current FGD Pond 2 has created a groundwater plume beneath the general area of the disposal ponds (FGD Ponds 1 and 2). This plume is presently controlled by a series of groundwater pump back wells which discharge the pumped water back into FGD Pond 2. The FGD Pond 2 does not meet the requirements of §257.71 – Liner design criteria for existing CCR surface impoundments, due to absence of an installed geomembrane liner and compacted clay soil liner. The Rule states that existing CCR surface impoundments are considered unlined if “the owner or operator of the CCR unit fails to document whether the CCR unit was constructed with a liner that meets the requirements of paragraphs (a)(1)(i), (ii), or (iii).”

On April 17, 2015, the Environmental Protection Agency (EPA) issued the final version of the federal coal combustion residuals rule (CCR Rule) to regulate the disposal of CCR materials generated at coalfired units. The rule is being administered as part of the Resource Conservation and Recovery Act (RCRA, 42 U.S.C. §6901 et seq.), using the Subtitle D approach. MidAmerican Energy Company (MEC) is subject to the CCR Rule and as such has developed a Fugitive Dust Control Plan for all sites handling and disposing of CCR per 40 CFR 257.80. This report provides the Fugitive Dust Control Plan for the George Neal Station North (Neal North) located near Sergeant Bluff, Iowa. This Fugitive Dust Control Plan is in addition to, not in place of, any other applicable site permits, environmental standards, or work safety practices. Bottom ash and economizer ash is handled wet and sluiced to CCR impoundments onsite. Since the CCR is sluiced in a wet condition via pipeline to site impoundments, there are no potential fugitive dust sources in the handling of bottom/economizer ash both at the source of the CCR and at the discharge point in the impoundments. MEC is currently evaluating converting the system to dry handling; should dry handling be implemented for any of the units at Neal North, there will be an amendment to this plan to address dust controls for drying handling.

Power Plant and Energy Projects Should Be Tracked from Inception
Fossil-fired power plants, refineries, gas-to-liquids, LNG and petrochemical plants are large investments. Initial decisions about suppliers are first made years in advance of the bid specification release. These decisions can be reversed by persuasive suppliers but it is much better to make the case prior to a tentative decision. McIlvaine supplies weekly and biweekly alerts to help suppliers ensure that they are heard at the earliest appropriate time. Coal, gas and diesel-fired power plant projects take years to develop from initial concept to actual operation. Decisions about sub systems are typically made two years before operation for a small gas turbine or diesel plant. These decisions for large coal-fired power plants are made three years in advance or earlier. On the other hand, decisions can be altered due to unforeseen events. The 3960 MW Saurashtra power plant in India is a project which has been underway for nearly seven years. The first two 660 MW units for Saurashtra are slated for 2019 start up. The new air pollution regulations will require 30 mg/Nm3 for particulate compared with 50 mg/Nm3, FGD for units 1 and 2 at 92 percent versus only provision for FGD in the existing permit. NOx emissions will be limited to 100 mg/Nm3 which would require more than 80 percent reduction. So any decisions relative to air pollution control systems have to be reviewed and new systems incorporated.

Yes, Landfill Gas Engines Will Produce More Poison Ivy but also More Tomatoes
A New York Times article warns of the impending growth of poison ivy. Yes, but this fertilization effect of CO2 has been put to good use by thousands of greenhouses around the world. GE, Cummins and other engine manufacturers are actively pursuing CHP projects which provide greenhouses with electricity, heat, light and CO2. Is it better to increase the production of tomatoes or retard the growth of poison ivy? The Southcoast Air Quality Management District (SCAQMD) struggled with this question in the recent analysis of the 1110.2 biogas emission amendment. The question is whether landfill gas engines would be a better choice than just flaring. The Beverly Hills estate owner who can easily buy whatever tomatoes are desired but is struggling to keep poison ivy under control will have a completely different value judgment than a starving child in Sudan. Should SCAQMD prioritize the desires of its residents above those of the starving people in the world? The answer is “Yes.” But this does not mean that every government in the world should reflect the values of SCAQMD residents. There is a broader implication …

Substantial NOx reductions with Ovation combustion optimization at Midwest coal plant
Emerson and a Midwest Power plant benchmarked pre-project NOX, O2, and steam temperature levels and burner tilt performance. Two improvements were identified, the addition of separated OverFire air (SOFA)dampers & tilts and combustion optimization in the plant’s Ovation control system. The OverFire air process redistributes air within the boiler combustion zone and injects additional air above the combustion zone to complete the combustion process. Decreasing the air within the burner zone lowers stoichiometry, which lowers the flame temperature and reduces thermal NOX. This also reduces the tendency of fuel-bound nitrogen to oxidize to nitrous oxides. To compensate for temperature excursions caused by rapid changes in SOFA positions, advanced control strategies were developed. These control strategies were based on an advanced non-linear, fuzzy-neural NARMAX (FNM) algorithm. The team followed a multi-step process, which included a study of the current combustion process, DCS control improvements, parametric testing, model development, open-loop testing, closed-loop testing, and commissioning. For this project’s optimization model NOX and CO were the control variables. Manipulated variables included the OFA and SOFA dampers, SOFA tilts, O2 trim, auxiliary air dampers, window-to-furnace differential pressure, fuel air dampers, and feeders. The disturbance variables included load, ambient temperature, total air flow, and burner tilts demand. Over the multi-year process that included the combustion optimization, followed by the SOFA equipment, followed by the advanced control optimization of the SOFA equipment, the plant reduced annual NOX output from over 1400 tons to under 600 tons.

Tampa Electric installs Emerson Smart Process system to optimize NOx control with new SCR
TEC entered into a contract with Emerson Process Management Power and Water Solutions to provide an Emerson Smart process combustion optimization system on TEC Big Bend Unit #4TEC This optimization system was installed, configured, and tuned in 2007. It is an in-combustion NOx reduction process that reduces the generated NOx emissions and the cost of the SCR operation. The primary goal of this optimization system was to determine the optimal positions for various combustion parameters to achieve multiple emission goals which are defined and can be modified by the end-user. As part of this combustion optimization and SCR projects, a new CO analyzer was purchased and installed on Big Bend 4 by TEC to provide the optimization system with critical on-line feedback for status of the boiler combustion system.

Constellation energy reduces Nox at low cost with emerson optimization system
In 2003 Constallation Energy completed a project to optimize the performance of two units at its C.P. Crane station in Baltimore, Maryland utilizing advanced neural network technology. The C. P. Crane site has two (2) units, each with four (4) Babcock &Wilcox (B&W) cyclonic furnace burners in an opposed-wall firing configuration. The NOx optimization portion of the project has provided the utility with significant reduction in the NOx emissions with a relatively small capitol investment that was recovered in the first five months of the project. This has allowed financial gains from several different aspects including the shifting of required NOx credits to other units and lowering the units’ power production costs, which has increased competitiveness in the dispatching system.

Constellation energy optimizes SNCR process with Emerson program
The SNCR optimization project at Wagner Unit #2 was coupled with the new equipment, revised operational goals, and control system revisions required for the SNCR integration and automated operation. The SNCR optimization project at Wagner Unit #2 was found to significantly decrease the NOx removal from the injection of the reagent in the furnace coupled with a new type of adaptive optimization system that significantly reduced the overall NOx emissions. This new technology eliminates manual parametric testing, and this novel feature enables a faster deployment and operational readiness than previous technology like neural network based systems. The combustion optimization system with SNCR system ON was able to reduce the NOx emissions to an average value 0.298 lb/MMBTU compared to 0.332 lb/MMBTU with optimization system off-line.

Minnkota optimizes coal fired power plant to balance erratic wind generation
The ability to effectively utilize the maximum amount of the wind farm production, while preventing transmission voltage surges, was a concern for Minnkota Power Cooperative. Conversely, when the wind would slow, the conventional assets are required to respond to prevent voltage sags. Minnkota M.R.Young power station is the primary source of electric generation for more than 110,000 customers. For many years prior to the wind farm additions Young station was base-load operated to meet the generation needs of the area. The main factors requiring a revised operational mode for the plant generation are twofold. The market was being deregulated by the creation of the Midwest Independent System Operator (MISO) of the transmission grid. Also new wind farms were put into operation nearby, causing additional load demand regulation issues and voltage problems with the electrical transmission lines. The Emerson URO project required significant changes to the Young Station operations to allow Minnkota to capture available wind generated electricity by efficiently cycling the Young Station to meet constant changes in the wind generated output. The scope of the URO project was to create new fully coordinated closed loop control strategies via the following method: 1. Capture detailed unit operating data via parametric testing by cycling the units through various power ranges. 2. Using that data to develop dynamic models of the unit‟s operating characteristics at various load ranges. 3. Testing and verifying those models under actual operating conditions. 4. Modification of existing control settings and benchmarking the new strategy vs. the base strategy. The upgraded software has provided many benefits. The unit is now able to hit targeted set points accurately and with minimal megawatt overshoot, thereby contributing to reduced fuel costs. The unit is also able to ramp to the targeted set point much quicker, enabling revenue to be generated more quickly. Because the unit is able to follow load demand it is now possible for MPC to compete in the ancillary power services market. In addition, the use of optimization technology can also translate into less stress on critical equipment, further enhancing unit reliability and availability.

Burner modification to entrained flow gasifier to eliminate thermal NOx entering boiler
Coal is fired with very limited hot air in an entrained-flow gasifier In the initial combustion step, the carbon consumes all the oxygen and creates a hot, fuel-rich gas and frees the sulfur from the coal, Limestone (CaCO3) provides calcium as CaO Sulfur reacts with CaO to form calcium sulfide (CaS) - a solid particle at these temperatures, CaS destroys the NOx (NOx< 10 ppm) to form elemental nitrogen (N2) At the high temperatures, coal ash (alumina & silica) mix with the CaS and melts to form a slag product; the sulfur is thereby encapsulated in the slag About half the slag drains from the chamber to a water quench slag tank. Clean red-hot gases enter the furnace & cool to < 2300 F, where thermal NOx formation is frozen. Any slag particles solidify to a fine fly ash Staged over-fire air is then carefully added to complete combustion in the furnace to CO2 & H2O and to avoid any thermal NOx formation. The hot exhaust gases exit the furnace to the back pass at the original design conditions.

Fuel –lean gas reburn injects gas in specific locations for optimum Nox reduction results. Since FLGR does not require a physical change to the main combustion system, it requires a relatively low capital cost, typically less than $8/kW. FLGR is different from conventional gas reburning systems because gas is injected in a manner that optimizes the furnace’s stoichiometry on a very localized basis. The process avoids creating a fuel-rich zone and maintains overall fuel-lean conditions. Efficiency improvements of up to 30 % are possible.

Opportunities for Data Analytics in Power Generation
Data science is defined as machine learning. One use is in Data Analytics which has four steps 1. Descriptive analytics ( what happened) 2. Diagnotic analytics (why did it happen) 3. Predictive Analytics ( when will it happen) 4. Prescriptive Analytics ( what should I do about it). Prognostics ( a combination of diagnostic and predictive analytics can be used to predict the time at which a system or a component will no longer perform its intended function . This is a challenge since most failures are random and not age relaed. It is important because of the cost of failure. Bearing Failures in Rotating Equipment cause $240B in downtime and repair costs. A combination of physics and data based models can be beneficially used for calculations of remaining useful life ( RUL) . The conclusions of the presentation are 1.Data analytics can help operators manage and improve reliability of generation assets. 2 Prognostics can be used to determine a RUL with a time element and confidence level. 3 Operators can use the RUL to actively manage maintenance schedule and operating conditions in order to maintain reliability. Data Analytics is a also applicable to efficiency ( fuel cost, capacity output) , emissions ( compliance and optimization ) , flexibility ( operational and economic).

Gasified sewage sludge as a reburn fuel
Gasified sewage sludge has been evaluated as a reburn fuel to reduce NOx in Polish coal fired power plants. New regulations in Poland relative to sewage sludge disposal combined with the large number of Polish coal fired plants encourage consideration of alternatives such as the gasification and use of sewage sludge as a reburn fuel. This paper presented at a 2013 water conference shows results of laboratory tests showing up to 40 % Nox removal. However, there is no claim that this reburn fuel would be more efficient than natural gas. The paper also references the use of gasified municipal solid waste and other biomass. The paper references successful gas reburn in European coal fired boilers including the system at Longannet. Successful reburn examples in MSW and other combustion facilities are also noted.

Using natural gas in coal fired boiler
Using gas to replace coal or to supplement coal or just for gas reburn can be economically attractive . In 2012 Riley Power Inc. (RPI part of Babcock Power) in conjunction with a major Southeast utility conducted a week-long program to test the boiler’s ability to fire full load natural gas in an existing RPI low NOx coal-fired burner. The goal was to determine the ability of the equipment to meet steam load requirements and emissions requirements. The result of this investigation is that the unit can achieve the original steam flow capacity and meet the current emissions regulations. However, substantial control changes will be necessary to ensure the unit can operate automatically on load control.

Zero Liquid Discharge Webinar - Hot Topic Hour February 25, 2016
The webinar yesterday provided a valuable exchange of information among ZLD system and component suppliers. One of the goals was to compare evaporation/crystallization to the spray drier for coal-fired power plants. All agreed that the comparison needs to be site specific. In some cases the spray drier is less expensive than the evaporation approach but the comparison was limited to FGD wastewater and not the entire plant wastewater discharge.

Pall filters reduce oil contamination in coal pulverizers
Power generation industry studies have shown that coal pulverizers are an area where improved equipment reliability is badly needed. The Electric Research Institute (EPRI) has determined that 1% of plant availability is lost on average due to pulverizerrelated problems. EPRI also identified oil contamination and excessive leakage as two areas where pulverizer drive train failures account for 53% of pulverizer problems.

Power Plants Will Spend $8 Billion for Valves In 2016
Power plant valve purchases will remain at a high level thanks to continued construction of new coal-fired power plants in China, Vietnam, Indonesia and Japan. Despite the fact that Japan was the host of the original greenhouse gas reduction convention (Kyoto Protocol), the country is planning 40 new coal-fired power plants. Old coal-fired power plants will be retired, so CO2 emissions will not be increased. The EU also is building new coal-fired power plants to replace higher emitting old power plants. In Asia, the need for new electricity and the lack of natural gas are the big drivers. Next year nearly 50 percent of the $8 billion power plant valve expenditures will be by East Asian power generators. NAFTA will be the second largest region thanks to construction of new gas turbine combined cycle power plants. These forecasts are provided in Industrial Valves: World Market.

Eliminating Feedwater Control Valve Damage with Multi-stage, Multi-path Flowserve Control Valves
The feedwater control valve (located downstream of the high-pressure feedwater heaters) performs the critical function of controlling the feedwater flow rate over a wide range of service conditions. During startup and shutdown, the feedwater control valve restricts flow by controlling near the closed position. The pressure drop across the valve is high, which can cause severe cavitation and noise. Over time, these severe service conditions will damage a control valve. Even a properly designed valve will not work well unless it is connected to a correctly sized actuator. An undersized actuator will cause unstable flow conditions while an oversized unit has a slow response to input signals. Flowserve has successfully addressed these issues with specially engineering multi-stage multi-path, or MSMP, designs. MSMP trim channels the flow through a series of orifices to reduce the pressure in stages. This prevents cavitation from occurring inside the valve. The velocity of the feedwater is kept low to prevent erosion of the valve body and to reduce noise and vibration. MSMP trim is customer-designed for the full range of service conditions. MSMP trim prevents cavitation when throttling near the seat but acts like a conventional control valve when controlling near the full-open position. As the pressure drop across the valve decreases, the cavitation also decreases and then stops. To maintain flow rate with decreasing pressure drop, the valve will open further and expose flow paths without orifices. The orifices are not needed at this flow condition because cavitation has stopped.

Corrosion Studies on GeoBrom® HG520 Partial Immersion Study
Brominated derivative products for mercury control… There was little to no corrosion observed on these coupons in the vapor space. Visually, all corrosion occurred in the liquid phase where half of the coupons were suspended. There was no increase in corrosion rate observed at vapor / liquid interface on any of the specimens. Based on this 90 day study, all specimens were less than 0.70 mpy corrosion rate with half the coupon below surface. Mild carbon steel (C-1018) gave the highest corrosion rate at 0.14 mpy at 20° C and 0.65 mpy at 50° C. All remaining specimens were under 0.10 mpy. ICP analysis of GeoBrom® HG520 samples refl ect elevated iron and chromium levels at end of the 90-day period. The maximum allowable corrosion rate for each specimen with GeoBrom® HG520 depends on the application.

Continuous-Blowdown Block Valve Reduces Startup Time
At Essential Power LLC’s Newington Energy Facility, the high-pressure (HP) steam-drum continuous blowdown system was designed to cascade flow to the intermediate-pressure (IP) steam drum. While the valve worked well for controlling flow, it did not have the degree of leak-tightness required for stopping flow from the drum during typical overnight shutdowns. An automatic full-port ball valve was installed upstream from the existing automatic control valve to eliminate the risk of flashing.

Electric Fuel Control Valve Streamlines Plant Operations
A Frame 6B-powered cogen plant in California was plagued with fuel-gas valve problems, usually requiring at least a man-shift’s worth of work each outage to disassemble, clean seats/plugs, and reassemble. One solution is to reheat the fuel gas to above the dew point (120-130F) in between the valves, but this is considered far from ideal. The better solution proved to be replacing the original valve with a “smart” electric control valve in the same location as the original and a separate solenoid-operated stop/isolation valve about 6 ft upstream—just outside and below the turbine enclosure.

Tyco valves for FGD – 2012 power engineering article
The primary considerations in slurry valve selection are reliability in function and design, abrasion resistance, and ease of maintenance. In addition, valves with a straight-through, unobstructed flow minimize the effect of abrasion and therefore reduce the need for maintenance. Different valve types can have significantly different effects on flue gas desulfurizer (FGD) scrubber reliability. Mechanical equipment within the plant is used continuously and requires periodic service. The right isolation valve can facilitate maintenance of the system’s major components without the need to shut down the plant and can avoid disruptive leakages, which can cause significant damage. For example, if leaked slurry collects downstream in the pump casings, it can cause the impeller to freeze and prevent it from turning when the pump is started. The resulting high start-up torque can then damage or break the pump shaft.

MACT Update Webinar - Hot Topic Hour - May 7, 2015
There are unique site specific factors which are more important in MACT than in MATS. The reason is that in cement, brick and other industrial processes the material being processed may create more air toxics than the fuel. The special focus for this Hot Topic Hour was on dry sorbent injection. The use of hydrated lime was also discussed.

MACT Compliance Options, by Pat Mongoven, Mississippi Lime, HTH 5-7-15
DSI with hydrated lime can allow SO2 & HCl reduction for both industrial boilers and cement manufacturers. Depending on the application and the facilities goals, a High Reactivity Hydrate may allow better removal or lower costs. In cement scrubber towers, DSI gave comparable removal rates to feeding a liquid slurry of hydrated lime directly to the scrubber tower.

SO3 Poses New Challenges and Opportunities for Power Plants
SO3 is a pollutant but it is injected into flue gas to improve particulate control. However, SO3 interferes with mercury capture. It is unintentionally created by SCR catalysts. It is the major component of condensibles in total particulate. SO3 control is key to a new approach to power plant efficiency improvement. Power plant decisions need to consider all the economic, operational and environmental impacts for each potential approach involving SO3. A number of decision trees need to be navigated and then revisited. The best route can be likened to GPS guidance. McIlvaine has created a system for making all power plant air quality decisions: 44I Power Plant Air Quality Decisions. A fast track decision tree on SO3 has just been posted in the system.

Successful mercury reduction in pilot study at Seminole (Golder presentation at EUEC)
Summary: Pilot testing successfully reduced effluent Mercury concentrations to < 225 ng/l. Pilot influent concentrations were lower than historical maximums. Pilot test process reduced effluent Mercury to < 40 ng/l after flocculation and settling unit operations were improved. Results obtained in October 2014 (higher effluent Mercury) need further review (ratio of organosulfide:ferric iron may be a key). Substantial colloidal fraction of Mercury was present. Effective chemical addition, flocculation and settling are necessary so that sand filters (current Seminole polishing process) can be utilized. Tighter membrane filtration might be needed.

Coal to Natural Gas Electric Utilities Repowering: Consequences for Valve Usage and Replacement
US power generating plants are converting from coal to other fuels in large numbers. In some cases the existing infrastructure is (to the extent possible) retained, with only the combustible material being altered. In the “middle” are plants that "repower" by using an existing turbine to run on steam from a heat recovery steam generator (HRSG) that draws (recycles) exhaust heat from a new gas turbine, together forming a combined cycle. At the other end of the scale are newly constructed power plants, which are predominantly gas-fueled. Each of these three repowering alternatives requires a different quantity of new valves, often of varying types.

The reducing environment produced by oxygen scavengers initiates and propagates flow-accelerated corrosion (FAC) in the feedwater system and other components of high-pressure steam generators, including heat recovery steam generators (HRSGs). Since 1986, FAC-induced attack has caused numerous failures, some with fatalities, at a number of power plants in the U.S. Yet, specifications for many new power plants both domestically and globally, and in which the condensate/feedwater system contains no copper alloys, continue to call for oxygen scavenger feed to the condensate. This document is a response to this misguided trend.

Comparative Study on Several Anti-Corrosion Materials for Power FGD System (几种防腐材料用于电力烟气脱硫系统的比较研究)
In the study organic-inorganic hybrid composite, epoxy modified silicone coating and vinyl ester flake mas-tic were comparatively used as several anti-corrosion materials that provided protection for flue gas desulfu-rization (FGD). The relationship between curing conversion rate of hybrid polymer and temperature was in-vestigated by differential scanning calorimeter (DSC). The adhesion strength, coefficient of thermal expan-sion and flame retardant properties of three anti-corrosion materials were measured and analyzed. A corro-sion test in 8% H2SO4 and 5% HCl at temperature cycle of 40˚C ~ 160˚C was applied to study corrosion re-sistance of several anti-corrosion materials. Gravimetric measurement and morphological observation of three materials before and after corrosion test were comparatively analyzed in the paper. The small weight change and good morphological structure of hybrid composite during corrosion test demonstrate that hybrid composite has better anti-corrosion properties than epoxy modified silicone coating and vinyl ester flake mastic.

Chinese Coal-to-Liquids and Gas Program Could Completely Change the World Energy Markets
China will increase LNG imports. Some predict imports of 110 billion cubic meters per year (BCM) by 2020. However, the cost of LNG is presently $16/MMBtu. This is an expensive fuel source when China has domestic options including coal-to-gas, underground coal gasification, and coal bed methane. China is therefore changing focus and is pursuing these alternatives. The biggest program includes building plants in the western and northern coal fields which will convert coal to gas. This gas will be piped across country and provide clean burning fuel for major eastern cities. It is the avowed solution to the smog problem. The reason for a huge coal-to-gas program is the low cost of the product from a reliable domestic source. Here are the cost components: …

Jim provided the following comparison between CEMS and Sorbent Traps - Method 30B includes HgP, which results in overestimation of gaseous Hg that may be significant at MATS Hg levels but not enough to impact RATA pass or fail Differences in HgT up to about 0.50µg/Nm3 (typically less, but sometimes more) may be explained by HgP when controlling Hg with ACI and/or Br. Will vary somewhat by coal Hg levels, PM emissions, ACI injection, etc. Bromine “interference” should not be a concern except possibly under extremely high furnace Br injection rates and is not a concern for brominated activated carbon.

Measurement Differences between CEMS and Sorbent Traps
This study examined some of the factors that could contribute to differences between Method 30B Hg measurements and those that result from Hg CEMS.12 The following conclusions can be drawn: • When Hg is not controlled, the contribution of HgP is generally not enough to result in a significant difference between Method 30B and electronic Hg CEMS. • ACI and Br addition for Hg control will increase HgP. When Hg is controlled to MATS control levels, HgP that makes it past the PM control device may be sufficient to cause Method 30B to overestimate the gaseous Hg emissions by a significant degree, but typically not enough to impact whether or not a RATA is passed. • At sufficiently high Br levels, there is a potential for Br to contribute to differences between Method 30B and Hg CEMS that are not explained by HgP alone. One possible mechanism is the reaction of Br on the probe filter (or other surface) with gaseous Hg. This will be exacerbated if the probe or filter surfaces are reactive (ie., not adequately coated), if the filter condition has deteriorated or if material with reactive surface has accumulated on the filter. Others have also suggested that interference with the sample conversion system may contribute to this difference. For most Br addition rates expected under practical conditions, this potential effect is not expected to be significant. • The use of brominated activated carbon will impact the difference between Hg CEMS and sorbent traps due to formation of HgP as a direct and intended result of controlling Hg. The increased HgP that makes it past the PM control device will contribute to a difference between Hg CEMS and Method 30B. On the other hand, Br released from brominated activated carbon does not appear to impact gaseous mercury measurements to any significant degree. • This paper explored some key factors that might impact the difference between Hg CEMS

Lafarge Mannersdorf installs a hot ESP and SCR
This plant installed a hot ESP to reduce the dust loading to a new SCR to 2 g/m3. This allowed selection of a relatively small amount of catalyst with narrow openings. This decision was made as an alternative of reheating gas and then locating the SCR at the tail end of the process. The unit has been installed since 2012 and is reported to be operating with some problems according to Bernhard Kopf of Lafarge. The problem is that the ESP is not meeting the predicted emission limits and is running much higher and therefore the catalyst requires periodic cleaning. However, deactivation has been negligible.

In 2009 a leading exploration, development and production company launched a project to extract oil and gas from the Olowi field off the coast of Gabon. The project involved an FPSO facility acting as a production centre for four wellhead platforms, and an existing vessel, was to be used in the operation. As part of a drive to ensure that safety provisions were as comprehensive as possible, it was required to replace all of the single isolate units on the floating facility with double block and bleed valves. Clearly, weight and space were both major concerns, and it was therefore essential that the new equipment was installed with a minimum of additional components and pipe work. A large number of valves were to be replaced – more than 150 in total – and, given the scale of the upgrade, the traditional method of installing additional single isolate units was unfeasible as it would have approximately doubled the weight and space required for the system. Oliver Valves supplied 161 Twinsafe valves with bore sizes ranging from 1in to 10in. The valves were flange mounted with a range of ANSI class 900lb and 1500lb fittings. The standard length of Twinsafe valves meant that the existing single ball valves could simply be replaced with a cartridge double block and bleed unit, with no need for any additional pipe work

Measuring Ammonia Slip from Post Combustion NOx Reduction Systems
In many facilities there may be room for process improvement that could reduce operating costs or provide revenue enhancement opportunities. Operating SNCR or SCR technology closer to its limit offers these benefits but increases the risk of high ammonia slip. The risk could be abated with the use of ammonia monitoring technology. But, except for gas-fired plants, continuous ammonia slip monitoring technologies have not been available at a practical price to facilitate these cost-saving or revenue enhancing improvements. Conditions that exist in high dust, high temperature, high NOx and/or high SO2 environments make most analyzer methods of continuously measuring ammonia unsuitable for application to coal plants. An overview of the technologies available for measuring ammonia in the high dust region downstream of a Nox reduction system and the status of their development is provided.

The majority of coal-fired Part 75 utilities in the United States are now using real time continuous Mercury Vapor monitors. ThermoFisher Scientific has sold more than 450 Mercury CEMS and the majority are installed and operational. These CEM Systems are true real-time monitors designed to comply with the stringent data availability criteria required by Part 75. In defiance of the D.C. Court’s vacature of the Clear Air Mercury Rule (CAMR), many states are moving forward with the requirement of continuous Mercury emissions monitoring systems. Since 1993, all thermal power plants subject to the Part 75 Acid Rain Regulations have been required to continuous monitor for the regulated emissions, SO2, NOx, and CO2. Continuous monitoring of Mercury emissions is also expected to be the most accepted monitoring method for obtaining reliable real-time Mercury emissions. The test results at all Mercury emissions evaluation sites have shown that Mercury concentration variability far exceeds that of other regulated criteria pollutants. Multiple types of “routine operational events” occur during normal boiler operation and often trigger dramatic changes in the concentrations of both Elemental and Oxidized Mercury.

Treatment Chemical Case Studies by Bruce Keiser, Nalco. - Hot Topic Hour April 10, 2014
Nalco offers chemicals to solve the mercury emission problem for coal-fired boilers. One chemical is designed to inject in the boiler, another is injected in the scrubber and a third in the wastewater. The chemical quantities can be varied in order to compensate for process variables. For example the SCR does a better job of oxidizing mercury when the catalyst is new than later in the campaign. As the oxidation potential deteriorates the quantity of chemicals can be increased.

Bromine can accumulate in the scrubber recycle. Confirmation of the accumulation was determined in a study at Lower Colorado River Authority (LCRA). John Grocki advised the attendees that there are big variations even between units at the same plant. There is a range of concentrations which can be of concern. Bromine and Chlorine cannot be treated the same and the combination has a different impact than either one independently. So whether there will be corrosion and which material is best to protect against it is based on the concentrations of both halogens. In addition to the scrubber itself, the injection of halogens in the fuel can have impacts on the air heater and ductwork.

Chemtura can supply bromine as calcium bromide or in many other forms. The company works with clients from inception through continuing operational support. Setting up calcium bromide systems is relatively easy but there is no reason to over-design and invest more than necessary or to under-design and create operational problems. Chemtura is conducting tests which show the impact of bromine in the gas and scrubbing liquor on the materials with which it may come in contact. The quantity of bromine added can vary to compensate for changes in the process e.g., changes in fuels or deterioration of the catalyst. Since activated carbon is quite expensive it makes sense to utilize bromine with the fuel to supplement the carbon under upset conditions.

Spray Dryer FGD at TEP Springerville
The dry FGD system for each unit comprises three spray dryer absorbers (SDA) with rotary atomizers and a reverse-air fabric filter. The Springerville Station receives high-calcium pebble lime via rail, and a pneumatic system transports the lime to a day bin located at each unit. Horizontal ball mill slakers convert the pebble lime to lime slurry, which is combined with a slurry of recycled material from the fabric filter just prior to being fed to the rotary atomizer. When the units were constructed, the dry FGD systems were built with a partial bypass, the result of which is that 75% of the flue gas is treated in the spray dryers and the bypassed flue gas is recombined with the scrubbed stream before entering the fabric filter. TEP, with S&L as Owner’s Engineer, implemented the following modifications to reduce NOX and SO2 emissions: • Installation of low-NOX burners and overfire air (NOX). • Installation of a fourth spray dryer and elimination of the flue gas bypass (SO2).

Gas Suspension Absorber / Description
One of the reasons for the high efficiency of the KC Cottrell GSA is that the reactor has been based on gas suspension technology. This means that a very large concentration of fly ash, dust particles and lime builds up inside the reactor. The concentration is normally 50 to 100 times as high as in a conventional reactor. The effect is further enhanced by the fact that lime, fly ash and by-products are recycled about 100 times in the KC Cottrell GSA system. A short erection period is achieved due to a modular design, offering enormous flexibility. Maintenance costs for the KC Cottrell GSA are extremely low compared to more conventional plants. One reason for this is the minimal wear and tear due to few moving parts and a very simple, uncomplicated and stationary nozzle.

Features and Benefits of KC Cottrell’s Gas Suspension Absorber (GSA) Technology
The lime can be injected either as a slurry, through commercially available two-fluid nozzle atomizers, or as powdered calcium hydroxide. The intense recirculation within the reactor promotes efficient acid gas neutralization, resulting in high removal efficiencies at low lime consumption rates. The nozzles are commercially available and can be changed out on the fly, without impacting scrubbing efficiency. The use of the cyclone to capture and recycle solids from the reactor vessel greatly reduces the demand on the downstream particulate collector. The slim profile of the GSA reactor vessel itself minimizes plan area requirements, which are frequently at a premium in retrofit applications

How to Reduce Catalyst Lifecycle Cost, Improve Reliability
Balancing the requirements of each SCR system in the fleet can be challenging. A system can reduce NOx by greater than 95%, but when the efficiency of the SCR is pushed beyond 85% and—or, if—the outlet emissions are less than 5 ppm, the system becomes much more sensitive to several independent system parameters. These include overall catalytic potential, effective ammonia injection/mixing in the flue-gas stream, flue-gas characteristics for inlet NOx, velocity, and temperature distributions.

China Can Remove Mercury at Low Cost Thanks to U.S. Developments 中国能以低成本除汞得益于美国的技术发展
In order to meet tough regulations in the U.S. technology developers have made great strides in creating low cost routes to achieve mercury removal from power plant exhausts. The cost is especially low if the plant already has a scrubber. China is installing scrubbers on nearly all its plants. As a result China can remove mercury with just a few percent increase in its air pollution control investment and operating cost. There have been some very significant recent breakthroughs which need to be communicated to the Chinese policy makers. To this end Mcilvaine conducted a webinar in Mandarin Chinese with two FGD experts . A presentation on removal technology was made by Bobby Chen of CBI Shaw. Questions and discussion was provided by Shiaw Tseng of Graymont. This presentation in Mandarin is available as a recording in the Mcilvaine Global Decisions Orchard and on Youtube.

European Fossil Power Market Taking a Surprising Turn toward Coal and Wood
The U.S. coal and logging industries are booming thanks to exports to Europe. Alternatives to these two fuels are much more expensive in Europe. At the same time, the carbon credit price has fallen to insignificance. The result is a great incentive for European power plants to burn solid fuels. These trends are being analyzed in the McIlvaine Fossil & Nuclear Power Generation: World Analysis & Forecast. The impacts on industrial boilers are being tracked in Air Emitters. The impacts on the FGD, DeNOx, precipitator, and fabric filter markets are also being analyzed in McIlvaine market reports. Here are some of the surprising developments in Europe:

Advatech Designs Zero Liquid Discharge Systems As Well As Scrubbers
Advatech is a joint venture between URS and Mitsubishi. They have sold many scrubber systems in the U.S. Mitsubishi is the largest scrubber supplier world wide. They are now emphasizing their water management abilities including zero liquid discharge. Advatech Water Management: As concerns mount over the quality and quantity of our water supply, regulatory limits on water usage and discharge grow more stringent. In many instances, water usage brings with it a significant expense, and going to Zero Liquid Discharge (ZLD) is either a necessity or an expected near-term requirement. ADVATECH has designed wet FGD systems for chloride concentrations up to 50,000 ppm so that the only source of purge is the free moisture in the disposal-grade gypsum. However, this approach can incur a hefty cost in the form of materials of construction and decreased limestone reactivity. To minimize cost, we have been at the forefront in developing low-capital technologies capable of eliminating liquid discharge from wet FGD while maintaining chloride levels in a reasonable range, all this without the need for an expensive and complicated wastewater treatment process.

Altech MIR 9000 Capturing Market Share for HCl Measurement
Here are recent CEMS orders received by Altech: Altech will provide a dilution system for SO2 and CO2 at a milling operation in Western U.S. The system will comply with 40CFR60. Altech will replace the CEMS at a utility in the Eastern U.S. The system will measure NOx, O2, and opacity from two oil-fired boilers. The unit will be 40CFR Part 60 compliant. A cogeneration facility chose Altech and their MIR 9000 to measure Nox, CO, CO2, N2O and O2. The system will be able to handle the difficult Nox conditions related to this facilities process. The O2 will be in-situ and there will be an opacity monitor. Altech is known throughout the industry for having expertise in the measurement of HCl. Often a difficult gas to accurately measure, the MIR 9000 is ideal for this application. A power plant in the Eastern U.S. chose Altech and the MIR 9000 to measure Nox, SO2, CO, CO2, HCl and O2. Altech will provide two MIR-9000's for a metals processing facility in the South that will monitor Nox, CO, SO2, CO2, O2, THC (VOCs) and Flow. This project will use Altech LCPD probe boxes. This is a good example of how the versatility of the MIR can allow for measurement of all of the mentioned gases with one analyzer.

Southern Co. said on July 25, 2012 that it plans to shut down about 4,000 MW of older coal-fired power plants, to continue operating 13,000 MW of coal-fired power plants, and to switch about 3,000 MW to run on low-priced natural gas from other fuels. Southern said it expects to spend nearly $1 billion less than previously planned on pollution-control equipment at its coal-fired power plants, thanks to changes that the Environmental Protection Agency made to its final rules limiting mercury and other emissions from coal-fired power plants. The changes provided utilities with more flexibility in the ways they can meet the new limits. Southern said it now expects to spend about $1.8 billion on pollution controls from 2012 through 2014.

Court Says TVA is Legally Responsible for Coal Sludge Spill
The Tennessee Valley Authority is legally responsible for a 2008 accident that sent five million cubic yards of toxic coal sludge oozing into a small community in eastern Tennessee, a federal judge ruled on Thursday. U.S. District Judge Thomas Varlan said the levee that was supposed to keep the wet coal ash confined failed because of conduct on the part of the authority. As a result, he said, the federally owned utility will have to pay unspecified damages to more than 800 plaintiffs who sued after the spill. "Had TVA followed its own mandatory policies, procedures, and practices, the subsurface issues underlying the failure of North Dike would have been investigated, addressed, and potentially remedied before the catastrophic failure," Varlan wrote. The TVA said in a statement that it had already purchased nearly 180 properties affected by the spill, settled more than 200 other claims submitted by residents and paid $43 million to the Roane County Economic Development Foundation for use by communities in the affected area. "Since the spill in December 2008, TVA's commitment has not wavered - to clean up the spill, protect the public health and safety, restore the area, and, where justified, fairly compensate people who were directly impacted," the utility said. Thursday's ruling signals the beginning of a new phase in their litigation against the TVA. The plaintiffs will now have to go back to court and prove that they were each directly impacted by the spill.

Court Vacates Cross-State Air Pollution Rule
In an opinion issued August 21, two judges on a three-judge panel for the U.S. Court of Appeals for the District of Columbia rejected and vacated EPA’s Cross-State Air Pollution Rule. This rule was finalized in July, 2011, and required 28 states in the East, Midwest, and South to reduce emissions of SO2 and NOx that cross state lines and worsen air quality in downwind states. "EPA's Transport Rule exceeds the agency's statutory authority in two independent respects," wrote Judge Brett Kavanaugh of the U.S. Court of Appeals for the D.C. Circuit in the decision. The rule violates the Clean Air Act by requiring states to reduce their emissions by more than their own significant contributions to downwind states' nonattainment of air quality standards, according to the decision. And the agency did not allow states the opportunity to meet their "good neighbor" obligations before imposing its own Federal Implementation Plans, Kavanaugh wrote. The Cross-State Air Pollution Rule (CSAPR) was EPA’s attempt to fix an earlier version, the 2005 Clean Air Interstate Rule (CAIR), which was thrown out by the D.C. Court of Appeals in 2008. Analysts suggested that it would take several years to rewrite the rule rejected on Tuesday. In the meantime, the Court said that “EPA [will] continue to administer CAIR pending its development of a valid replacement.”

Cross-State Air Pollution Rule Decision Will Have Only Minor Impact on the Equipment Market
The McIlvaine Company forecasts that this development will change the U.S. FGD and NOx control market forecasts by less than ten percent over the next five years. It will have less than one percent impact on the world markets. See link for the present forecasts in FGD World Markets and NOx Control World Markets.

Arizona Opposes EPA's Visibility Plan to Install New Expensive Pollution Control Equipment
State officials and utilities are trying to kill a plan by the U.S. Environmental Protection Agency to force owners of three coal-fired power plants to install expensive pollution control equipment to improve visibility. State officials argue that the federal proposal to reduce NOx will impose hundreds of millions of dollars of unnecessary costs on utilities — and, by extension, their customers. The proposed reduction is also believed to have no affect on public health, instead it is based on EPA’s claim that the pollutants are impairing visibility in natural parks. This controversy pits economics against visibility. The state believes that putting such a restriction on the power plants is part of the current administrations plan to make fossil fuel power not cost effective, and thus not worth while to the customers.

Electronic treatment removes silica scale in power and semiconductor applications
Silicate has a special form, which is called covalent bond, but most scales have an ionic bond so ion exchangers or Reverse Osmosis Systems are available for removing them. But ion exchanger or RO System can’t remove silicate scale. In addition, silicate scale can’t be dissolved by acid cleaning. Also the magnet treatment developed in the West is subject to restriction in the size of pipe, flow velocity and so on. Furthermore, it is developed to remove scales caused by hard water. Its effect on soft water like in Japan has not been proved. Scalewatcher ,electronic water treatment equipment, made it possible to remove silicate scale which was impossible by chemical treatment or magnet treatment device within a short time

Indonesia is rich in geothermal resources and at present, it accounts for about 2.5% of the total installed capacity. However, while geothermal resources offer the potential for 20, 000MW of electricity, only 4% (787MW) has been developed in the past 20 years. The geothermal resources of the plant Dieng #1 contain a lot of Si in steam, making scales cling to steam production wells, steam tubes and steam turbines. As a consequence, at present, it only generates 40MW of electricity compared to the expected 60MW output. Despite there have been several measures taken, such as the injection of acid (which is also done in Japan) none have been effective in solving the problem. Agency for the assessment and application of technology (BPPT) asked Tohoku Electric Power Co. Inc to examine the scale problem in the plant through its overseas projects.

Silica Scale problems Occur in Western U.S., Southern Europe and pacific Rim
The solubility of amorphous silica is important to the operation of water-dominated production processes. In areas such as Texas, New Mexico, Arizona, parts of California, southern Europe, the Pacific Rim and Latin America, the water used for industrial applications contains high silica concentrations (50 parts per million [ppm] to 100 ppm, expressed as silicon dioxide [SiO2]). These concentrations result from quartz (crystalline SiO2) dissolution from rock formations into the groundwater. The potential for silica-scale deposition poses serious problems in water with a high dissolved silica content. In fact, silica-scale problems could be termed the Gordian Knot of water treatment," such problems are extremely difficult to resolve. Personnel responsible for power plants, evaporative cooling systems, semiconductor manufacturing and geothermal systems must monitor water silica levels very closely. Silica precipitation/deposition frequently is encountered in evaporative cooling systems, where salt concentrations increase through partial evaporation of the cooling water. Silica solubility in water generally is 150 ppm to 180 ppm, depending on water chemistry and temperature. This imposes severe limits on water users, leading either to operation at very low cycles of concentration and consuming enormous amounts of water, or to use of chemical water treatment techniques that prevent silica-scale formation and deposition.

Xylem Flygt 4600 mixer used in lime slurry tanks and ore processing
The 4600 series mixers are ideal for lime slurries because of the two abrasion resistant options tungsten carbide or silicon carbide. With 8 different models, this makes it also a good option for ore processing. WCCR has superior sliding properties meaning considerably less wear between the two seal surfaces offering a longer life with less risk of leakage. It offers better mechanical strength and is far less brittle and sensitive to handling damage than SiC. WCCR has a binder where chromium, nickel and molybdenum have been added giving excellent corrosion resistance down to a pH of 3. SiC has the advantage when the pH is lower than 3 or when mixing small particles that are harder than WCCR.

Physical-Chemical, biological and ZLD are all used for FGD wastewater
Options for Treating FGD Purge Wastewater • Physical-chemical treatment to reduce total suspended solids, adjust pH, de-supersaturate the purge stream, and reduce heavy metals. Since 2004, about 14 systems have been installed and are operating in the United States; 27 more are under construction. • Biological treatment to reduce selected heavy metals (such as selenium), and/or organics resulting from use of organic acids, and/or to reduce total nitrogen (usually due to ammonia slip from a selective catalytic reactor). This system is usually preceded by a physical-chemical system to protect it from scaling and suspended solids overload. Since 2004, about eight biological treatment systems have been installed or are planned for installation at FGD wastewater facilities. • Zero liquid discharge (ZLD) using thermal units (evaporator, crystallizer, spray dryer). Only one was operated briefly in the United States in the 1990s, but it experienced scaling, plugging, corrosion, and high capital and operations and maintenance costs. Two more have been ordered in recent years, with one under construction and one canceled during construction. • ZLD using deep-well injection. One is in operation in the United States, and one is under construction. This option costs $5 million to $6 million per well, with two to three wells per site. This system also requires a physical-chemical treatment system preceding it to reduce suspended solids and to de-supersaturate the wastewater to prevent scaling in the high temperature, high pressure deep-well environment. • Sludge stabilization by mixing FGD purge with fly ash for land filling. None are currently being built; however, about 15 were constructed in the 1970s-1980s. This approach eliminates the ability to sell fly ash for commercial products and requires extra landfill volume. • Stacking the gypsum for either final disposal or future reclaim. This will absorb some of the purge in the stack. Liquid runoff is collected in holding basins, mixed with ash water, or held in solar evaporation ponds (in favorable climates). A couple of these designs are under construction but could be required to retrofit to treat the gypsum stack runoff. • Constructed wetlands treatment system. Only three have been completed, and performance has been mixed.

The water consumed by power plants is about half of the total annual industrial water consumption in China. Considering some characteristics of wastewater in power plants, the paper presented a new process to treat the wastewater. In the process, wastewater was made centralized treatment utilizing activated sludge firstly, then water purifying agent was put into the wastewater and they were coagulation sedimentation. The wastewater was treated by aeration and disinfection at last. In order to increase the efficiency, the ash conveying water was used as the cogulating aid in the process. The experimental results showed that the presented process was effective. The quality of the wastewater after treated was stabile and the ash conveying water was beneficial to the flocculation promotion. The effluent was well used for the circulating cooling water system. It can be concluded that the wastewater of power plants can be the supplementary water of the circulating cooling water system after appropriate treatment. The engineering practice indicated that the process can reveal the social, economical and environmental benefits and be helpful to the realization of the zero discharge of the power plants.

Current and Future Trends in Water and Wastewater Treatment at Power Plants
This is an excellent report prepared by the UK's Department of Trade and Industry providing an assessment of the current state of development and application of water treatment technologies relating to utility and industrial scale fossil fuel-based power generation. Future areas of development are highlighted as well as the current state of the market and its future prospects. The power generation industry is predicted to remain a very significant industrial market for water treatment equipment and associated products. Increases in future global electricity demand are expected to be met primarily through large- scale fossil fuel-based power plants. Coal is projected to retain the largest share of power generation, but with natural gas-fired plants expected to become increasingly important. The main future markets for new fossil power plant are seen as China and India. China represents the largest single market in the world for new power plant equipment currently due to substantial long-term demand for increases in power supply. Coal is the main source of fuel for power generation in China and natural reserves are extensive. The use of coal is expected to grow substantially up to 2030, with the installation of new large-scale boiler plants. China is pursuing Clean Coal Technologies as a means of meeting future energy requirements, with supercritical boilers and Integrated Gasification Technology being attractive options. The power sector in India is dominated by coal and use is projected to increase threefold from 2000 to 2030. Ultraviolet technology along with ozone is sited as an emerging and novel treatment technology. There has been an increase in the use of UV technology as it eliminates the problems associated with the addition of chemicals with respect to factors such as disinfection by-product formation, safety factors in handling and storage, and economic factors. The use of UV radiation in conjunction with ozone or hydrogen peroxide can further enhance the efficacy of the overall disinfection process. Worldwide, with increasing limitations on clean water supplies and increasingly stringent environmental legislation, it is expected there will be a greater need to treat alternative low- quality water supplies. The successful application of these advanced technologies for treating such waters will be ever more important for future fossil fuel power generation.

This article highlights Hanovia and how they have successfully used UV to reduce total organic carbon (boiler feedwater) for Kaeng Khoi 2 Power Plant in Thailand. This is a gas-fired thermal power plant generating capacity of 1468 MW, 7.5% of Thailand's total power consumption. The facility was designed to meet Thai and World Bank environmental regulations and the the electricity being generated is sold to the Electricity Generating Authority of Thailand (EGAT) under a 25 year power purchase agreement. A key component to the success of this project was the elimination of TOC from boiler feedwater which can vary greatly. It was found that UV can break down trace organics which cannot be removed by other processes. The original source of the boiler feeder water for this plant is from a local river, which is stored in a raw water pond before being pumped into the water treatment plant. There are two medium pressure UV chambers used for treatment at this plant which have been very effective in addressing the seasonally varying feed water quality. The two Hanovia UV chambers treat a combined water flow of up to 400m3 per hour. Actual TOC input to the UV chambers is 183ppb and output is 58ppb - a 68% reduction which is well below the required minimum required concentration.

Dr. Yougen Kong, P.E., Technical Development Manager at Solvay Chemicals, Inc., discussed dry injection of Trona or sodium bicarbonate, a low-cost solution to meet the SO2 and HCl limits in CSAPR, Utility MACT and Boiler MACT. Both Trona and Sodium bicarbonate are effective in reducing SO2 and HCl. Trona is slower to react and therefore less effective on SO2 but possibly better if all you want is HCl removal. Lots of the bicarbonate will be tied up in SO2 removal. So if you want to just remove HCl Trona may be the answer.

The Proposed Utility MACT Rule, by Brian Higgins - Nalco Mobotec -Hot Topic Hour October 4, 2011
Brian Higgins, Vice-President for Technology at Nalco Mobotec, Inc., discussed compliance strategies for the proposed rule. In particular, he noted the difficulty of using particulate matter CEMS (which measures only filterable PM) to demonstrate compliance with a total particulate matter standard. He also discussed issues associated with the ash from DSI systems used to achieve compliance with the HCl limit.

Kasi Dubbs, Managing Consultant at Trinity Consultants, summarized the methods and processes used by EPA to set emission limits for the Utility MACT rule. Her presentation was particularly effective in showing the impact of EPA’s “Franken-plant” approach to setting the MACT floor. For example, of the top 20 performing units for PM, only one unit was also on the list of top 20 performing units for total suspended metals. Similarly, of the top 20 units for SO2, only one unit was also on the list of the top 20 units for HCl. She also identified other issues associated with EPA’s method for defining the “top performing 12%” of units in establishing the MACT floor.

Carl V. Weilert, Principal Process Engineer at Burns & McDonnell, discussed “The Good, the Bad and the Ugly” aspects of the proposed rule. On the positive side, he noted that the proposed rule allows for averaging among multiple units at a facility. On the negative side, he discussed why the test methods and processes for measuring total particulate matter were unreliable and questioned EPA’s assumption that dry sorbent injection (DSI) could be used to achieve compliance with the HCl limits. He also pointed out that the MACT limits for new units were too low and could effectively block any new fossil-fuel projects.

Construction of small hydropower stations in a central China nature reserve has triggered worries among locals over the ecosystem damage to the best reserved forest zone in the country's hinterland. The development of hydropower in Shennongjia forest district in Hubei Province dates back to the 1970s, when the region's government encouraged locals to use hydropower as an alternative to wood as fuel for better preservation of forests. However, hydropower stations are a double-edged sword, said Liu Shengce, deputy secretary-general of the forest district's Communist Party committee. On one hand, forest resources have been well preserved as fewer trees fell, Liu said. However, rivers in the forest district have been cut off after nearly 100 small hydropower stations were built. Yao Chucheng is one of the locals frustrated with the reservoirs. The 42-year-old has invested about one million yuan ($156,250 U.S. dollars) over the past six years on fish farming by the river of Guchong that runs through his village of Changfang in the forest district. A hydropower station under construction on the upper stream of the river threatens Yao's business. The 25,000-kilowatt hydropower station by Shennong Green Valley Hydropower Company will cut off the water supply to Yao's fish farm when it commences operation. In 2006, the government of the forest district stopped approving hydropower stations below 3,000 kilowatts and vowed to shut down 38 small stations before 2020. Yet no stations have been closed since, as they are indispensable in providing cheap electricity to locals. Liu Shengce said the government needs to work on a compensation plan for locals to pay for their losses if the hydropower stations are closed and demolished. "Also, locals will involve themselves in the protection of the nature reserve only if they benefit from the protection," Liu said.

Dow HDPE water pipe for nuclear power plant
As this was to be the first ever use of HDPE in a safety-related water pipe system at a nuclear plant in North America, the team at Callaway had to create a material specification and related procedures from scratch. In the process, they underwent a change in mindset from focusing on what was available to specifying what was really needed. Most importantly, Callaway engineers began to work closely with members of the HDPE pipe value chain. These players included The Dow Chemical Co. (Dow) as the HDPE supplier, WL Plastics Corp. as the pipe manufacturer, and Independent Pipe Products Inc. for the manufacture of special pipe fittings. The consultant, Frank Schaaf, Jr. of Sterling Refrigeration Corp., was also instrumental in the work necessary to gain approvals from the NRC. Callaway team selected CONTINUUM DGDA-2492 Bimodal Polyethylene Resin from Dow as the raw material for its new ESW secondary water pipe system. According to the team at Callaway, this installation is a first important step toward HDPE becoming a preferred material for safety-related water pipe systems at nuclear power stations. AmerenUE is already planning to replace other buried piping with HDPE in other systems in 2009.

Improving Precipitator Performance by Randy Cook - Alstom Power - Hot Topic Hour August 25, 2011
Randy Cook, Manager of Business Development at Alstom Power, Inc, observed that contrary to popular belief, many of the existing ESPs can be rebuilt to meet the stringent emission requirements of pending regulations. A combination of multiple technologies for mechanical and controls upgrade will have to be used in most installations depending on fuel, existing ESP sizing and configuration. Changing electrode geometry, installation of high frequency power supplies, optimized rapping, advanced controllers with opacity optimization, power down rapping, and off flow rapping can achieve significant PM emission reduction without adding plate area or replacing the ESP by a fabric filter. If upgrade of the ESP alone cannot meet the emission requirement, it may be cost-effective to install a downstream polishing fabric filter.

Greg Carleton of Pollution Control Services, Inc said that the majority of existing ESPs are not operating under their original design basis. Many existing ESPs have not been upgraded with modern operating philosophies or equipment. Taking a holistic approach in evaluating the precipitator in its current operating parameters permits a viable forward plan. It must take into consideration that the operating parameters have been modified as post combustion control equipment like SO3, NOx, and Hg control have been incorporated over the last few years.

Market for WESP Stainless Plate
I talked to Buzz Reynolds of Siemens. He said all the specs call for 3/16” or greater plate. At Trimble County, they are using 6 moly and 2205 at Prairie State and Dallman. He thinks Spurlock is 2205 and Elm Rd. is 317 Lm. Buzz said they use a special design which was confidential but you could describe it as something more than 3/16. So maybe it is some shape other than just flat plate. : 1) How many WESPs have been installed? At least 100 world wide in power and thousands in acid mist and other chemical/refinery applications. Belco division of DuPont is big with the EDV in refineries. They may have close to 100 installations. The EDV is a hybrid between a WESP and a scrubber 2) Forecasted mkt for WESPs? It is about 5% of the potential of FGD but lots of stainless as a percentage of the total market. The problem may be the sizes do not fit your offerings 3) Approx Lbs of plate required per WESP…Power Plant WESPS are as big as the scrubbers. So there is lots of plate See the draft of the article in Air Pollution Control for more details on this market.

Brian Adair, Ph.D, Director of Technology Development at SCR-Tech, LLC a CoaLogix Company, discussed fuel impacts on SCR catalysts from a catalyst management perspective. SCR-Tech has experience with all types of catalyst (honeycomb, corrugated and plate-type) being exposed to all types of coals, blends, temperatures and operating conditions. Its unique perspective seeing all the catalyst types with the different fuels types has led to the following observations Consult your SCR Catalyst Manager to model fuel change impacts on catalyst life and system performance. Less expensive coal generally “trumps” more frequent catalyst replacement; but total economics and system performance must be evaluated. Most important factors to determine catalyst type, formulation and geometry: o Ash content o Sulfur content o Arsenic & calcium content o Operating temperatures o Flue gas velocity

Ruediger Peldszus, Senior Manager for Applied Technology Advanced Intermediates at Evonik Degussa GmbH, backed up his claim that TMT 15® is a good choice for separating heavy metals from flue gas scrubber water by citing a large number of installations in coal-fired power plants and also waste incineration plants. When asked how the chemical impacted the gypsum quality, Ruediger explained that the resultant compound is very small and exits the top of the hydroclone and not with the gypsum through the bottom. TMT 15 can also prevent mercury re-emission from the scrubber but for this to be successful, the parameters must be carefully evaluated. One of the participants has a client who has been challenged to successfully use the TMT 15 to prevent re-emission

Michelle L. Briscoe, VP of Analytical Services at Brooks Rand Labs, observed that evaluating the effectiveness of specific FGD wastewater heavy metal removal methods requires the collection and analysis of samples for metals concentrations at each stage in the treatment process. Because of interferences, testing is showing metal concentrations which are much higher than actual. Brooks Rand Labs has developed methods to eliminate the interferences and provide accurate measurement.

Excellent cost to performance ratio for Duplex stainless in FGD demonstrated by Industeel
An analysis by Industeel based on a number of FGD installations demonstrates the corrosion resistance of duplex stainless. The cost advantage of duplex over austenitics has continued to increase. Industeel has prepared a selection guide based on chloride content in the recirculating slurry. Duplex has proved its advantages for most systems. However, where chloride levels are excessive Ni-base alloys should be considered. The super austenitic grade UNS S31266 can also be an alternative.

Alfa Lava to Supply Heat Exchangers for Largest Concentrated Solar Power Plant
Alfa Laval has received an order in the US to provide Alfa Laval Packinox heat exchangers to the world’s largest concentrated solar power plant. The order value is substantial and well in line with the largest reported over the past 12 months. Delivery is scheduled for 2012. “We are very proud to be part of such a ground-breaking project in the important area of renewable energy”, says Lars Renström, President and CEO of the Alfa Laval Group. “It is a unique order in many ways; it includes a unique product and will to be used in the world’s largest solar power plant.” The Alfa Laval Packinox heat exchangers, specifically developed for this application, will be the heart of the thermal storage system where heat from solar power is stored in molten salt, thereby enabling electricity production even on rainy days or at night. The solution will allow the plant to operate for additional 6 hours on stored energy, i.e. from 12 to 18 hours – an increase of about 50 percent over normal daytime solar power production, which better matches the demands from the local power consumers. This is the biggest solar power order so far for Alfa Laval, who has developed solutions for solar power pilot plants during several years and has today a number of references from countries in the world’s solar belt.

Solar Receiver for Concentrated Solar Designed and Installed by B&W
In 2008, Babcock & Wilcox PowerGeneration Group, Inc. (B&W PGG) was awarded a contract to designand manufacture a solar receiver to harness the sun’s energy to produce superheated steam to generate “green” electricity. In August 2009, Babcock & Wilcox Construction Co., Inc. (BWCC) installed the 50 ton (45,000 kg) receiver atop a 150 foot (46 m) high stand-alone tower. Because BWCC is a wholly owned subsidiary of B&W PGG, the material design and manufacturing supply were fully integrated into BWCC’s final installation plan. This close working relationship enabled the team to safely raise the solar receiver to its final position in less than six hours. Pictures and details are displayed on the B&W website

June 2009 marked the initial coal-fired operation of the world's first supercritical pulverized coal-fired low mass flux vertical tube Benson boiler. Jinzhushan 3, located in Hunan Province in the People's Republic of China, is a 600 MW B&W PGG VTUP™ once-through boiler with vertical tube furnace construction designed to burn Chinese anthracite using downshot pulverized coal technology. The boiler was supplied by Babcock & Wilcox Beijing Company, Ltd. (BWBC) under license from B&W PGG. This paper reviews the development history of supercritical, once-through steam generator technology and product advancements. Downshot pulverized coal combustion technology is used to efficiently utilize low volatile anthracite coal that is difficult to burn conventionally. The unique design features of the downshot combustion system are reviewed as well as the adaptation of this technology to the VTUP design. Both the SWUP and VTUP boiler designs can be supplied to meet the market requirements of today’s supercritical pulverized coal applications. The SWUP boiler represents a well-proven solution that provides consistent heat dis¬tribution to all tubes flowing through the furnace circuits making it insensitive to the natural variations that occur in furnace heat flux patterns that result from variations in fuel characteristics and types burned, boiler cleanliness conditions, air staging for combustion NOx control, and changes in pulverizer operating conditions. The VTUP boiler offers a solution that takes advantage of the benefits of natural circulation where tubes exposed to surges in heat flux will draw more flow to cool the tube instead of reducing flow due to higher resistance. The successful operation of Jinzhushan 3 demonstrates that this process works as expected and offers an alternative that has advantages of simpler construction, a less complicated wall support system, and lower furnace pressure drop contributing to more efficient net plant electric generation. Both the SWUP and VTUP furnace designs represent good alternative technologies for supercritical boiler applications that can be used to meet the needs of the modern power plant. The full paper can be downloaded from the B &W site as BR#1849 Successful Operation of Jinzhushan 3, the World's First PC-Fired Low Mass Flux Vertical Tube Supercritical Boiler

The following link provides a photo of the stand at Electric Power and a further link to details on the ZLD system at Patriot. This posting to the Global Knowledge Orchard is courtesy of Industeel, a supplier of steels used in ZLD systems. Patriot Renewable Fuels in Annawan IL. included the option to operate as a ZLD facility in the interests of conserving water.. During 2009, Patriot made the decision to voluntarily convert (as opposed to a regulatory mandate) to full ZLD operations and eliminate the discharge stream. Water usage was at approximately 2.9 gallons of water per gallon of ethanol produced prior to implementing ZLD. During the transition, water usage has been reduced to about 2.0 gallons per gallon of ethanol, nearly a one third reduction. This amounts to a savings of 100 million gallons of water per year. An article about this plant appears in Water World. http://www.waterworld.com/index/display/article-display/5870175047/articles/industrial-waterworld/volume-11/issue-2/feature-editorial/renewable-fuels-facility-implements-zero-liquid-discharge.html?cmpid=EnlWaterWorldIndustrialMay242011

Wet flue gas desulfurization (WFGD) Systems and the associated wastewater treatment (WWT) plants are typically designed separately with little or no direct communication of design conditions between vendors. In the current economic climate the emphasis on cost reductions thru improved design conditions and innovative design approaches is essential. The basic design factors for the purge stream are the volumetric rates of the purge stream, the chlorides concentration, and the weight percent solids. These factors have significant impacts to the costs of both the WFGD system and the downstream WWT system. The optimization of these design factors will minimize the overall design costs of project. This paper will examine the process and cost impacts of designs from five projects that have both a Siemens WFGD and a Siemens WWT system and provide design recommendations for future systems.

Power facilities and others relying on water as a means of cooling may be facing the need to make significant changes to their intake system to be compliant with the pending 316(b) ruling. This ruling is promoting safer fish handling, among other environmental aspects, and the EPA is planning to identify the Best Technology Available (BTA), which may be a variety of solutions, cooling towers or closed loop systems at the top. Solutions Some groups propose that closed loop cooling systems are the best solution for 316(b) compliance and ultimately the most environmental friendly. While this may seem like a sustainable solution, for the plant it can require major construction to retrofit the facility to accommodate a closed loop system. This construction can be costly and require the plant to stop production for some time, or worse, close the plant down. Many of these facilities are facing very tight budgets and making the most economical decision is important. The decision must be made carefully, considering the risk of costing the community jobs, impacting the local economy and ecology. A large portion of the market affected by the most up to date 316(b) rulings are currently utilizing Once Through Cooling rather than Closed Loop Systems. If given the chance to implement alternative water screening and handling technology, power generators and others using cooling water must evaluate more effective and affordable solutions while still meeting the core requirements of 316(b). There are solutions that may satisfy the demands of environmentalist, the EPA, and power plants. During this discussion, a fair comparison on these alternative technologies will be presented, along with our best available EPA 316(b) ruling update.

The electrical generating community is aware of the U.S. EPA-proposed first-time nationwide regulations for handling and disposal of coal ash residuals (CCRs) including fly ash, bottom ash, and flue gas desulfurization (FGD) byproducts. Option one (Subtitle C) makes CCRs subject to hazardous waste requirements under the Resource Conservation and Recovery Act (RCRA). Option two (Subtitle D) establishes stringent requirements under non-hazardous classification similar to municipal solid waste rules, also under RCRA. The industry is buzzing with speculation regarding the form of the final rule, timing, litigation and how to influence change. The critical question is “what is this going to cost?” Timely budget planning, decisions, and actions are necessary to prepare for minimum requirements common to both options, with sufficient flexibility to adapt should the more stringent classification be approved. In addition to new dry disposal requirements, existing wet ash and FGD handling systems may be phased out entirely, requiring conversion of equipment, addition of dewatering systems, and closure of ash ponds. Some states already have similar disposal requirements; others have no such regulations. Using the combined resources of detailed cost analysis for specific sites, adjustments from municipal and hazardous waste regulations and costs, trade and association summaries, existing regulations, local economic conditions, computer models, and 30 years of disposal records for other wastes help to develop high confidence level cost estimates. This paper presents an up-to-the moment rule status summary, key points of the CCR proposal and discusses optional engineering solutions available for compliance along with associated costs using the Total Cost Accounting approach. Potential impacts on beneficial uses (recycling) of CCRs are difficult to predict but must be factored into the financial decision making process.

This paper will take a brief look back at the history of SO3/H2SO4 concerns, from the “pseudo” particulate issues of the 1970s, current mitigation techniques, a review and comparison of extractive SO3 test methodology and the current need for real-time SO3 monitoring. The concern over SO3/H2SO4 formation in back-end coal fired boiler emissions has increased with the introduction of Selective Catalytic Reduction (SCR) units to control NOX emissions. Prior to SCR usage, it has been the corrosive nature of SO3/H2SO4 and its’ affect on downstream equipment and ductwork, that has fueled efforts to understand its’ formation and the means to control or mitigate its’ affects. In addition, SO3 emissions can cause opacity accidences, interfere with activated carbon control of mercury emissions and bias particulate test results. Wet chemistry test methods do not provide real-time data often needed to minimize additive fuel rates used to control SO3 emissions. To both lower opacity levels while maintaining ESP fly ash conditioning, a facility will undertake a series of process control modifications; additive feed rates, and even comparison of different additives. These operations are time consuming and costly. The use of a real-time SO3 monitor allows sources to make these changes and receive feedback in a timely and cost effective manner. A comparison of the Controlled Condensate wet method and real time monitor test results will also be provided. The benefits of a real-time SO3 analyzer (vs the CCM approach) will also be discussed as they pertain to ease of set-up and operation, results by method, cost, and the ability of each method to provide information in a timely manner.

As new regulations become more stringent and inclusive of additional requirements, utilities are being forced to modify the operation of their plants. Many are looking to their SCR catalyst to help meet these challenges. Choosing the optimum catalyst is an increasingly important decision because it not only ensures that utilities will comply with current regulations but it can also give utilities the flexibility to meet those that follow. Catalyst manufacturers continue to develop new catalysts that enhance the performance of the SCR, providing low cost solutions that give the required flexibility while minimizing the operational impact to the unit. This presentation will review the various factors that are part of the catalyst design and selection process including the catalyst performance requirements and the anticipated operating conditions. Discussion topics will include low load / low temperature operational impacts, SO2 to SO3 conversion minimization, mercury oxidation promotion on low halogen fuels, handling of large particle ash, and more. Finally, the operational and economic impacts of catalyst management programs will be reviewed.

Ameren has been a leader in lowering NOx emissions. In 1990 AmerenUE, now Ameren Missouri, an Ameren subsidiary, implemented a long term emission reduction program. Based on NOx emission rates in 2009, Ameren had 13 of the top 20 plants nation-wide including the top 4 for T-fired coal units without SCRs. These reductions can be attributed to the addition of OFA, boiler tuning, utilization of combustion optimization software, and Ameren’s dedication to reducing NOx emissions by maintaining a group of combustion engineers. Ameren will discuss recent advances in this area.

Based on a Federal Court decision the US EPA has agreed to propose the National Emission Standards for Hazardous Air Pollutants (NESHAP) for Coal- and Oil-Fired Electric Utility Steam Generating Units. This NESHAP is to be proposed by March 16, 2011 and promulgated by November 16th, 2011. This NESHAP, and the associated requirements for MACT (Maximum Achievable Control Technology), are expected to be very similar in form to the Industrial Boiler MACT. The MACT floor, based on EPA regulations, cannot be less stringent than the average emission limitation achieved by the best performing 12% of existing sources for subcategories with 30 or more sources, or the best-performing 5 sources for subcategories with fewer than 30 sources. Accordingly at least 90% of the Utility industry will be affected by the emission standards promulgated under this MACT. The MACT requirements will require upgrades and modifications to existing emissions control equipment and the installation of new control systems to limit emissions of mercury, the other criteria metals, acid gases such as HCl, and organics. This presentation will address the potential impacts on existing Utility Assets and discuss the implications and limitations of existing control technology to control the air pollutants addressed by this NESHAP.

Study was conducted at a 5-MW equivalent slipstream facility of Gulf Power’s Plant Crist Unit 5 located in Pensacola, FL. The facility is also commonly referred to as Mercury Research Center (MRC). During the trials lasting 10 days, the effect of a range of process variables was studied. The variables included flue gas temperature, air-to-cloth ratios, interval between cleaning, and the effect of removing some of the fly ash by an ESP upstream of baghouse, etc. GE tested a novel membrane-based filtration media formed as pleated elements. Data will be presented that shows that by using GE’s novel filtration elements, Mercury capture as high as 98% can be achieved by inherent fly ash alone (without needing to inject powdered activated carbon). This was true in spite of majority (about 80%) of Mercury being in elemental form in the flue gas. Traditional round filter bags are typically known to capture around 30 to 40% of Mercury in the flue gas by inherent fly ash. Data was also collected with injection of activated carbon upstream of baghouse. It was found that by using these novel filtration elements, if a plant is already using powdered activated carbon the consumption of activated carbon can be reduced by as much as 85%. Data will be reviewed along with the proposal of mechanisms about how this novel filtration element works in achieving such high Mercury captures, as compared to traditional round bags.

Dry injection of sodium sorbents (trona and sodium bicarbonate) has been proven as an important multi-pollutant control technology due to (a) its low capital cost, (b) small installation, © easiness to operate, and (d) flexibility to fuel changes. Trona has been used as the main sodium sorbent due to its relatively low price. However, for some power plants where higher SO2 removal rates are desired and amount of generated fly ash need to be minimized, sodium bicarbonate (NaHCO3) offers a good alternative. For these reasons, a power plant that has been using trona since Fall 2005 tested conversion from trona to sodium bicarbonate on a 100 MW boiler. Trona or sodium bicarbonate was injected upstream of a hot-side ESP. The flue gas temperature at the injection point was around 600 oF. For 80% of SO2 removal, the normalized stoichemetric ratio (NSR) with trona was 2.5. With milled sodium bicarbonate, the required NSR for the same SO2 removal rate was decreased to 1.0. Over 97% of HCl was also removed. As a result, less sorbent was needed and significant savings in the sorbent was achieved. Furthermore, less fly ash was produced due to the sorbent change, and resulted in lower fly ash disposal cost. Same as trona, the sodium bicarbonate was able to keep the stack opacity below the limit since both sodium sorbents were able to lower the fly ash resistivity and thus enhance the ESP performance.

Draft U.S. Environmental Protection Agency hazardous air pollutant regulations for coal-fired utilities are anticipated by March 2011, and the expectation is that very high emission reductions (90% or greater) will be required for mercury control. Activated carbon injection (ACI) is expected to be a key tool for achieving these reductions; however, typical performance data with ACI suggest that in-flight mercury capture becomes exponentially more difficult at high reduction levels. Because of this decreasing sensitivity of mercury capture to carbon injection rate, ACI parameters will need to be optimized in order to consistently achieve high reduction targets. Unfortunately, optimization data may not exist for a number of plants since existing site-specific data may have been collected with outdated mercury capture targets in mind, and the ultimate capture potential or its sensitivity to plant operations was not thoroughly examined. To add to this dilemma, optimizing the maximum mercury reduction with ACI is not a trivial matter since there are number of potential bottlenecks that can limit overall capture. These restrictions range from insufficient sorbent distribution and contact time in the flue gas, to one of many kinetic limitations that arise under the conditions encountered in flue gas. This presentation will discuss the common mechanisms that limit mercury capture with ACI, as identified through fundamental study of mercury–carbon interactions and analysis of pilot and field data. Recognizing the typical trends with mercury capture can assist in the selection of ACI parameters that are most likely to achieve high reductions that may be mandated in the near future.

Dry Sorbent Injection (DSI) is being considered more frequently as a cost effective means of mitigating emissions of acid gases (SO2, SO3, HCl), heavy metals (Hg), and toxic organic compounds (dioxins and furans) from coal-fired boilers. A variety of dry sorbents are being considered, including sodium based compounds such as trona and sodium bicarbonate, calcium based compounds such as hydrated lime, and various activated carbons. Many existing power plants are equipped with electrostatic precipitators for controlling particulate emissions. Electrostatic precipitators can be very sensitive to operating conditions such as flow rate, temperature and to the quantity and chemistry of the particulate matter entering the ESP. Injection of sorbents upstream of an existing ESP changes both the quantity and the chemistry of the particulate entering the collector. This can change the performance of the ESP. When deciding whether to employ Dry Sorbent Injection, operators need to know what effect it will have on their existing equipment. Can they meet the required particulate emissions with existing equipment or will they need to upgrade their ESPs or even replace them with fabric filters? This paper will review several case studies wherein a variety of dry sorbents are injected upstream of an existing ESP. As will be discussed, the effects vary, depending on the design of the existing collector and on the amount and type of sorbent injected. The paper will also discuss mitigation options to enhance the performance of ESPs with dry sorbent injection.

Over the past several years, a significant number of FGD systems have been placed in operation. At each site, absorber materials of construction have varied based on plant preferences and industry experience. A portion of absorber vessels were constructed of solids alloy material such as 6% moly stainless steel, alloy 255, alloy 2205, and 317 LMN. Other vessels were built out of carbon steel, lined with flakeglass or rubber. Also some FGD units were constructed of concrete that is lined with ceramic tile. This paper will examine several SESS installations that have utilized ceramic tile lined absorber vessels. The discussion will include design experience, general arrangement considerations, construction issues, and schedule limitations that must be considered with this absorber arrangement. In addition, internal inspection observation will be presented from several sites, including Dominion Chesterfield 6 , PPL Montour, PPL Brunner Island, and Constellation Brandon Shores.

An air pollution control system was installed at Dominion Generation’s Chesterfiled Plant in April 2008. The air pollution control system includes limestone injection, fabric filter, and a single absorber module to control emissions from the Chesterfiled plant’s number 6 boiler unit. The unit burns medium to high sulfur eastern bituminous coal. For sites such as this, a dry electrostatic precipitator has typically been used to control particulate emission. Recently, however, fabric filters have been installed at several installations to control particulate emissions under these conditions. With this type of emission control arrangement, ash loadings to the FGD are generally much lower than a typical dry ESP / Wet FGD arrangement. The are several advantages of operating a Wet FGD system with low ash loadings. Under this operating scenario, equilibrium inert / ash concentrations of the scrubber will remain quite low (usually under wt 2%) and absorber solids concentrations is mostly gypsum. Low concentrations of ash minimizes the potentialal of Wet FGD chemistry issues, such as aluminum fluoride blinding. Chemical analysis of the absorber slurries that are equipped with Fabric Filters upstream indicates lower concentrations of some dissolved metals, such as Selenium that is an important regulatory species. The low ash content of the FGD also results in very low gypsum moistures values (5% - 8%) to while operating with a typical hydroclone, vacuum filter system. Additionally, equipment wear is lessened as highly abrasive ash particles are not present in high quantities. SESS will present photos of absorber equipment from the most recent outage (September) 2010 at Chesterfield 6.

Lisa JN Bradley, Ph.D., DABT, Senior Toxicologist and Vice President Environment at AECOM, discussed “Perspectives on Health Risks Associated with Beneficial Re‐Use of Byproducts of Coal Combustion.” EPA stated in their June 2010 proposed rule for the disposal of coal combustion residuals (CCRs) that their intention was to preserve the Bevill exemption for the beneficial use of CCRs. However, the preamble to the proposal was essentially an advanced notice of proposed rulemaking for the regulation of these uses. This contradiction was evident in testimony given by EPA at the recent hearing of the House subcommittee on Environment and the Economy on the McKinley bill (HR 1391). EPA’s Office of the Inspector General has also recently issued a report titled “EPA Promoted the Use of Coal Ash Products with Incomplete Risk Information.” Her talk provided encouraging results for risk assessments and risk-based evaluations for the beneficial uses of CCRs, and how EPA’s own CCR risk assessment can help inform the issue.

Richard (Rich) Staehle, Vice-president of Business Development at Marsulex Environmental Technologies, related the evidence to show how high efficiency FGD using ammonia instead of limestone (AS-FGD) has been commercially demonstrated in full-scale systems for well over a decade. This process uses the SO2 as a feedstock in the production of ammonium sulfate, a valuable crop fertilizer. In addition to significant revenue potential from the fertilizer sales, this technology minimizes or eliminates the solid and liquid waste costs and liabilities associated with conventional FGD systems. Experience at Dakota Gasification is that this granular fertilizer is preferred over alternatives. Therefore a big storage dome supplied because of assumed seasonal demand has not been needed. As soon as it is produced the ammonium sulfate is sold.

Eric Erickson of Haldor Topsoe updated participants on the Haldor Topsoe SNOX technology, an exothermic, catalytic process for the removal of SO2 and NOx from flue gas. SNOX generates additional heat recovery and merchant grade sulfuric acid. It is ideal for high sulfur coal and petcoke applications as it becomes more efficient and cost effective as the sulfur content of the fuel increases. In the discussion period it was agreed that this process can easily be adapted to the new toxic regulations by using sodium additives ahead of the particulate device to remove the HCl (without injecting enough to remove SO2).

Power Industry Experience Using Micro Media Filtration and Short Bed Ion Exchange Geoff Hong, Eco-Tec Inc. With the demand for higher efficiencies and lower maintenance and operating costs for boilers and turbines, high purity water treatment systems are becoming more crucial to the operation of power plants. Modern power plants, operating at supercritical and ultra supercritical boiler pressures and temperatures, require such high purity water that it is approaching theoretical levels. High efficiency gas-fired combustion turbines, which use high purity water for NOx control and sprint mode, heat recovery steam generators and once through steam generators also require high purity water for the same reasons. Effective pre-treatment for reverse osmosis (RO) and ion exchange (IX) demineralizer systems not only contributes to the production of high purity water, but also helps to reduce the operating and maintenance costs of those systems. The versatility and efficiency of short bed ion exchange systems produce high purity water from feeds of variable characteristics, with lower chemicals consumption and waste volumes. This paper discusses the use of micro media filtration as a pre-treatment for RO or IX systems and the use of short bed IX systems for the production of high purity boiler feed make up water and condensate polishing. The experiences of several installations are outlined for applications in power generation and cogeneration plants.

RO Membrane Pretreatment Ken Robinson, Avista Technologies Pretreatment continues to be a subject that turns up on a daily basis when dealing with RO (Reverse Osmosis) process. Even though pretreatment requirements are well established for RO, the power utility market as a whole tends to see more of these issues as compared to other industries. Part of the reason for this trend is that feed water supplies tend to originate from surface sources while other factors tend to be more directed at equipment and design specifications. This presentation will focus on a number of pretreatment strategies that various power utilities have dealt with over the course of the last couple of years. RO system cases involving softening, coagulation, ultrafiltration, and media filtration will be covered along with RO process issues such as scaling, filtration, and biogrowth. In each of these cases, solutions will be presented on how to best mitigate the problems and show how analytical techniques can be used to fine tune and minimize the impact of the problems.

A New Approach to On-line Sodium Measurement David Gray, Mettler-Toledo Thornton, Inc. Sodium has been a critical measurement parameter for ensuring water treatment performance and purity for nearly four decades. Monitoring cation exchange performance and the purity of makeup water, steam and condensate has benefitted from measurement of this key parameter. Many refinements have been made to the ion-selective electrode method for on-line sodium measurement for these applications. Described here are yet further improvements to this technology including an unique integrated electrode system that measures both sodium and pH to assure proper reagent delivery. The system design minimizes reagent consumption and reduces maintenance requirements well below current practice. The new sodium system uses a particularly simple automatic calibration method and also provides the ability to measure grab samples easily. Its implementation with an operator interface common to other parameters including conductivity, dissolved oxygen, pH and ORP makes it especially convenient for installation and operator training.

Comparison of Dissolved Oxygen Measurement Technologies Kenneth Kuruc, Hach Company Dissolved oxygen measurement in the steam cycle remains a key parameter for the monitoring and control of corrosion. A variety of methods, including colorimetric and electrochemical (galvanic and polarographic), continue to be employed as either field test, portable or process platforms. However, most methods to this point have required a fair amount of attention and expense in order to maintain proper operation. In this paper we will discuss the traditional methods along with a relatively new technology known as “optical” or “luminescence”. The significance and potential advantages of this new technology for the power industry will then be considered.

On-Line Water Chemistry Measurements for Power Plants Ravi Jethra, Fred Kohlmann, Bhupen Patel, Endress + Hauser Inc. At the center of every efficient power plant, there is a well run water treatment system. Correct water treatment is crucial to provide high purity water to pre heater, boiler, steam and condensate systems, as well as other systems using boiling-water reactors and pressurized water reactors. The quality of makeup and feed-water is required to be monitored continuously to detect chaining water quality parameters (WQP). These changes in WQP usually indicate maintenance, upsets, leaks, and carryover. The long term data review of WQP also helps to study the gradual trends for prevention of corrosion or scaling. In case of inadequate measuring systems, these conditions may result in increased or unscheduled maintenance, higher capital cost, lower efficiency of heat transfer surfaces, and less profits due to down time. As newer and better technologies increase the power plant efficiencies in other area, the allowable limits on water quality become increasing important. Therefore, the requirements of WQP measurements become more important. The paper discusses data from case histories on water quality. In addition, the authors discuss how WQP measurements can be utilized to implement savings in reagents in the treatment process. The information presented in this paper would be helpful to operations managers, maintenance staff, and process owners of water treatments associated with power and steam utilities.

Overview of Microbiological Control & Monitoring In Utility Cooling Systems K. Anthony Selby, Water Technology Consultants, Inc. Cooling water systems in electric utility plants face challenges related to corrosion, mineral scale deposition, microbiological fouling, and suspended solids accumulation. Of these challenges, microbiological control is a primary issue because it can impact the others. In addition to a direct impact on heat transfer, microbiological growth can influence corrosion, trigger mineral scale formation, and accelerate suspended solids accumulation. This overview will discuss the common methods of microbiological control in power plants as well as discussing some emerging technologies. It will also emphasize the importance of monitoring the effectiveness of microbiological control and discuss current monitoring methodology.

Do Neutralizing Amines Have a Role in the Treatment of High Purity Boiler Feedwater? James (Jim) Robinson, Luis Carvalho, Robin Kluck, Richard Krichten, GE Power & Water – Water & Process Technologies Neutralizing amines have been widely used to treat high purity boiler feedwater since at least the 1940s. Notable benefits have been derived, however some consider the use of these amines to be risky. In addition the use of organic chemicals for boiler feedwater treatment often causes steam and condensate cation conductivity levels to exceed current power industry and steam turbine vendor guidelines. The benefits that can be derived and questions concerning the use of neutralizing amines are presented to help plant operators assess the potential value of using them in their systems.

Karin Madsen of Haldor Topsoe discussed the effect of operating conditions and catalyst type on mercury oxidation across the SCR catalyst. Up to 90 percent mercury oxidation is achievable depending on the inlet Hg speciation and the chlorine concentration. Greater than 91 percent mercury removal is achievable using existing control devices (the combination of the SCR-FGD strategy). Adding additional HCl above a certain point does not improve oxidation. However, bromine acts differently and therefore may provide greater oxidation with increased amounts.

New DeNOx Approaches by Dr. Brian Adair, CoaLogix - Hot Topic Hour April 7, 2011
Brian Adair, Director of Technology at CoaLogix, coined a new term in his presentation calling SRCs “Multi-Pollutant Reduction Reactors” or MPRRs because they should now be looked at as devices to control SO3 and mercury as well as NOx. The focus of his talk was why an operator should treat a catalyst as an asset rather than a consumable. He stated that operators need to balance the different goals of deNOx, SO2 conversion, NH3 usage, pressure drop and mercury oxidation and to have a different way of long term planning. When a catalyst layer is no longer optimum for the operating conditions, it can be traded in for a different type or formulation or sold to another plant where it will achieve their objectives.

Robert (Bob) Crynack, Business Development Manager for the Peroxygen Division of FMC Corporation, described a process under development by FMC that utilizes hydrogen peroxide to control NOx from combustion sources and industrial processes. Injection of peroxide into existing ducts oxidizes the NOx, primarily NO, to other nitrogen species that can be captured by existing downstream equipment such as wet scrubbers, CFB scrubbers, spray dryer absorbers or dry injection (lime/trona) with ESP or FF. The technology is intended for coal-fired power plants that desire NOx reductions of 40-80 percent with minimal capital investment and low operating and maintenance cost. While it has been proven that hydrogen peroxide will oxidize NO, NO2 and even mercury, the ability of downstream equipment to capture the NOx and mercury are still being evaluated.

Shiaw Tseng, Marketing Manager at Graymont, Inc., described a multi-pollutant control system for existing coal-fired power plants using lime-based Circulating Dry Scrubbers (CDS) to remove SO2, SO3, HCl, and HF. He presented the results of performance guarantee tests conducted at the AES Greenidge Station Unit #4 (107 MW) burning eastern bituminous coal (2.5 to 3 percent sulfur) with a CDS and baghouse. These tests showed pretty impressive reductions of SO2, SO3, Hg and HCl to levels that were well under the limits in the proposed utility MACT. Advantages of this system include a relatively small footprint, fuel flexibility (including biomass), low water consumption and dry byproducts (no wet sludge). Interestingly, the CDS system achieved better mercury reduction than using ACI under the same operating conditions, indicating that ACI is not required. These systems are currently operating at 14 plants in the U.S.

Jim Sutton, Director at Alstom Power, discussed CO2 reduction through increasing energy efficiency in coal-fired boilers. Lots of CO2 could be avoided by making improvements in many areas. For example just using a more efficient transformer rectifier with a precipitator significantly reduced the parasitic load. There is a huge potential when the average heat rate for the U.S. fleet is 10,761 Btu/kW-hr for an efficiency of only 31 percent. Jim showed a group of older power plants with heat rates above 15,000 Btu/kW-hr, so the potential CO2 reduction for these old power plants is very large.

Jeffrey Phillips, a Senior Program Manager at the Electric Power Research Institute (EPRI), provided an overview of the U.S. Dept. of Energy's and Ohio Coal Development Office's Advanced Ultrasupercritical Boiler and Steam Turbine Materials Development Program. This is a $50 million, 9-year effort aimed at increasing steam temperatures by more than 250°F above the current state-of-the-art. This remarkable effort has now resulted in a code case submission to the ASME Boiler Code committee for a new material which can operate at the targeted conditions. Approval of this material will open the door to the most significant improvement in the thermodynamic performance of coal-fired power plants in 50 years. You can learn more about this at an April 7 conference also covered in this Alert. One of the important discussions following the talk was regarding the possibility to design new coal-fired boilers to eventually operate in the advanced ultrasupercritical state but to initially operate at efficiencies substantially higher than the old power plants they replace. So the old plants could be immediately replaced with major benefits.

Keith L. Pronske, President and Chief Executive Officer of Clean Energy Systems (CES), covered technology derived from the aerospace industry. Pressurized oxy-combustion of coal can create a zero emissions power plant. Future coal-based power generation systems may utilize de-carbonizing technologies that permit carbon dioxide (CO2) to be captured and stored. Oxy-combustion of gasified coal (synthesis gas or “syngas”) permits capture and utilization of high quality CO2. In the oxy-combustion power plant cycle proposed by CES, syngas and high-quality oxygen provided by an air separation unit (ASU) are combusted to form a working fluid composed primarily of steam and CO2. This high-temperature gas directly drives turbines to produce electricity, after which the steam is condensed and the CO2 is captured and stored. This technology enables use of coal or other hydrocarbon fuels with essentially zero atmospheric emissions. Biofuels can be gasified along with the coal. Thus this system would be even greener than solar or wind. It could be a net CO2 reducer. Every kWh of electricity generated results in extraction of CO2 from the atmosphere.

Dr. Fernando Preto, Senior Scientist and Group Leader for Biomass Conversion at CANMET Energy Technology Centre, discussed the co-firing of lignite with wood (pine) residues and peat focusing on emissions and ash deposition. His presentation reviewed the effects of fuel blending ratios, excess air, and moisture content on air emissions (CO, SO2 and NOx) from co-combustion of wood residues and peat with lignite. Co-firing leads to significant differences in the concentrations of some major inorganic compounds (e.g. SiO2, CaO, MgO, SO3) in deposited ashes. There was a discussion of the combustion of municipal waste (MSW). Fernando made a very important point. Their research shows that the presence of sulfur reduces dioxin formation. So burning MSW in a coal-fired boiler has a beneficial impact on emissions. McIlvaine pointed out the advantages of using the chlorine in the waste to convert mercury to a soluble form. It was further observed that with the new Utility MACT rules power plants will have the air pollution controls to deal with MSW.

Co-firing Wood with Coal by Desmond Smith, BRUKS Rockwood. Hot Topic Hour March 17, 2011
Dr. Desmond Smith, Ph.D. Vice-President at BRUKS Rockwood, Inc, discussed biomass handling and preparation prior to co-firing. Co-firing wood and biomass with coal in a suspension burning boiler requires that the fuel be prepared in specific ways to be effective in the way it performs. Conventional coal preparation machinery does not process biomass. It is necessary to control moisture to allow the machinery that grinds the organic fuel to produce a finely ground product that can be transported and injected pneumatically. The potential of using a gas to gas reheater such as Mitsubishi and Hitachi are using to reduce precipitator temperatures was discussed. A good way to extract heat from the system without paying an energy penalty would be quite attractive.

Ajay Kasarabada, an Air Permitting Manager in Black & Veatch Energy Division's Environmental Management Services Section, and Diane Fischer, Manager of Business Development for Air Quality Control Projects for Black & Veatch’s Power Generation Services, described a method for avoiding the need to comply with the Boiler MACT – “the non-solid fuel pathway”. They presented a methodology by which boiler operators can evaluate the technical and economic issues related to converting boilers to operate on “Gas 1” or “Other Gas 1” as defined by the EPA or decommissioning solid fueled boilers and installing new gas-fired boilers or gas turbines. Gas 1 units, Other Gas 1 units and combustion turbines do not have to meet Boiler MACT emission limits. Diane’s portion of the presentation focused on the benefits of considering co-generation and provided a detailed methodology for evaluating this alternative. They indicated that Black and Veatch is involved in studying these alternatives for a number of boiler operators but they have not yet reached any firm conclusions. However, now that the Boiler MACT has been issued, they are moving forward rapidly.

Enhanced Mercury Oxidization (EMO) by Steve Baloga, Shaw - Hot Topic Hour March 10, 2011
Steve Baloga P.E., a Senior Environmental Consultant at Shaw Environmental & Infrastructure, described a process for economically reducing mercury emissions from boilers combusting bituminous or sub-bituminous coal. EMO™, a liquid brominated oxidant, is injected into the gas stream at the exit of the boiler or economizer to convert elemental mercury into the oxidized version that is more readily captured by existing control equipment. With very low injection rates, this can be an effective low cost solution to achieve the new lower limits required by the MACT. He presented data on several boiler trials that demonstrate the viability of this low cost approach.

Mack McGuffey practices environmental law as an associate in Troutman Sanders' Atlanta office and specializes in regulatory compliance under the Clean Air Act. Last November at the last webinar on the IBMACT before the rule was published, he gave a very good presentation on the status of the ruling and potential future litigation. Now that the rule is out, Mack was able to provide an overview of the MACT program, explain how EPA's final Industrial Boiler MACT standards differ from the ones it originally proposed, and describe some of the legal issues associated with EPA's final rule. A key point made was that although EPA indicated that because of concerns over the legality of the significant changes between proposed rule and final rule, EPA is taking comment on the final rule, any delay in or stay of the deadline for compliance is very unlikely. He also emphasized that affected boiler operators must do whatever is necessary to comply with the new emission limits. Just installing additional control equipment will not be sufficient.

Industrial Boiler MACT - Impact and Control Options - Webinar March 10, 2011
On February 23, 2011 the U.S. EPA issued “Sensible Standards” for Boilers and Certain Incinerators that cut the cost of implementation by about 50 percent from an earlier proposal issued last year. Because the final standards significantly differ from the proposals, EPA believes further public review is required. Therefore, EPA will reconsider the final standards under a Clean Air Act process that allows the agency to seek additional public review and comment to ensure full transparency. EPA's reconsideration will cover the emissions standards for large and small boilers and for solid waste incinerators.

David Early of Combustion Technologies Corp. told attendees that combustion optimization at coal-fired power plants can be achieved with the use of various instruments that are available today but did not exist just a few years ago. Low NOx burners give power plants the ability to control air to each burner - yet most don't have a measurement to tell how MUCH air each burner is getting. Accurate measurement of burner secondary air (SA) is now available for ANY low NOx burner so that control with the burner SA can be optimized. Likewise, the amount of coal flow to each burner can be continuously measured and controlled for best combustion practices. Combined, these devices can be used for continuous control and provide for significant efficiency increases. Also the CO can be measured and controlled.

Expansion Joint Proper Design by Christopher Dyjak, Effox-Flextor - Hot Topic Hour February 24, 2011
Christopher L. Dyjak, Manager for Expansion Joints at Effox-Flextor, a CECO Environmental Company, emphasized the importance of utilizing proper application information in the initial design of expansion joints. One example is a joint in an FGD system. If the temperature could potentially drop to the dew point, then it is a more difficult application than if there were not the risk of acid corrosion. External insulation is recommended when the temperatures will never exceed the fabric limit and there is the potential for acid condensation.

John Darrow, Associate at W. L. Gore & Associates, Inc., discussed expanded polytetra-fluoroethylene (ePTFE) based products that could provide solutions to new compliance challenges for PM, dioxin/furan (D/F) and mercury. There was a summary of the potential for ePTFE membrane filter bags for PM control, REMDIA catalytic filtration systems for D/F control and a new carbon polymer composite material for mercury control. The composite material was of great interest to the participants who asked about pressure drop (low), efficiency (70-90 percent in addition to the scrubber removal) and elemental mercury removal (high). Testing is taking place at the Southern Yates station with EPRI also involved. This technology could be used as a second step if the initial attempt to remove mercury in the scrubber falls short. Since this device follows the scrubber it is better suited for a plant with a scrubber. Activated carbon would be injected ahead of the scrubber and would have the effect of reducing the amount removed in the scrubber. Therefore large amounts of carbon would be required to gain small efficiency increases.

Boiler MACT? - Prelude to Utility MACT by Robert Fraser, AECOM - Hot Topic Hour February 17, 2011
Robert (Bob) Fraser, QEP, Senior Technical Director for Power Generation Services at AECOM Environment, reported that the Utility MACT rule is likely to follow the form of the Industrial MACT rule which is now most likely to be issued on February 21st. EPA is using the same general procedures to develop both sets of standards. One of the concerns is the organics limits for both the Industrial and Utility MACT may be inversely rather than directly proportional to the CO. During startup and shut down there are high levels of CO and this could be a problem. It may be better to address dioxins and furans under work practice standards rather than limits.

Improving ESP Performance Webinar - Hot Topic Hour January 20, 2010
ESP Performance Improvement can be Substantial - Hot Topic Conclusion on January 20 There has been lots of focus on replacing ESPs with baghouses to meet upcoming regulations. The speakers in the Hot Topic Hour yesterday said there is an alternative. You can upgrade existing ESPs and achieve results which may satisfy future requirements. Dr. Yougen Kong, P.E., Technical Development Manager at Solvay Chemicals, Inc., told the attendees that “there is a better alternative to SO3 for conditioning electrostatic precipitators.” Trona addition system is simple and its capital cost is much lower than that of a SO3 production and injection system. Trona is relatively inexpensive and can be injected in several places. Mick Chambers, Southern Environmental, Inc, said that you can upgrade your ESP and with halogen-based additives in the coal, you can meet the particulate and mercury regulations. He showed that the SCA of recent installations has been relatively low and yet the performance high. So the footprint of a retrofit does not have to be large. When asked about the wet ESP using a fabric for the collection plate, Mick said that it is a good option and successful on industrial boilers and process applications. We were sorry to learn that John Caine passed away in a tractor accident last September. John had represented SEI in several of our previous Hot Topic Hours and has long been a contributor to the industry. Steve Jaasund, Manager Geoenergy Division A. H. Lundberg Associates, made a case for adding a wet ESP after the FGD system to meet the upcoming MACT regulations. In the discussion period it was speculated that the new mass monitoring requirements would make it more difficult for dry ESPs to meet emission limits. The wet ESP will eliminate the exceedance spikes associated with a stand-alone dry ESP. Paul Leanza of Pollution Control Services, Inc. indicated that many utilities have the opportunity to greatly improve performance of their existing precipitators. He indicated that 50 percent of the emissions occur during rapping (rapping reentrainment). These particles are relatively large and do not cause opacity spikes proportional to the mass increase. It was speculated that with mass monitoring this phenomenon will be an unpleasant surprise. Emissions will be higher with mass monitors than they were thought to be with opacity monitors and periodic stack testing. Ron Landreth of Albemarle was pleased to find that their brominated PAC actually improves precipitator performance whereas the non-brominated PAC may add to emissions. So it is worth considering brominated PAC to capture mercury and reduce particulate. Jean Bustard of ADA-ES (ADA Environmental Solutions LLC) related experience with a proprietary conditioning chemical which has performed well and does not impact mercury capture with PAC. The company offers another approach to conditioning hot side precipitators.

Coal Ash Ponds and Ash Disposal Issues Webinar - Part II - Hot Topic Hour January 14, 2011
Two very enlightening days of discussions on the CCR issue. The extended period for public comments on the proposed rule on Coal Combustion Residuals (CCR) (commonly referred to as coal ash) concluded on November 18, 2010. According to the speakers we can expect a final rule promulgated in 2011 or 2012. The big question is “Will the final rule classify CCR as special wastes subject to regulation under Subtitle C of RCRA (Resource Conservation and Recovery Act) when destined for disposal in landfills or surface impoundments (essentially hazardous waste) or as non-hazardous wastes regulated under Subtitle D of RCRA?” If EPA decides to classify CCR as “hazardous,” under Subtitle C, EPA would create federally enforceable requirements for ash management, including waste generation, transportation and disposal. If CCR is declared non hazardous, under Subtitle D, EPA would only mandate a set of minimum national standards and leave it up to state governments and citizen litigation to enforce them.

Ari Schoen Lewis, Environmental Toxicologist and Manager of the Toxicology Team at Gradient Corporation, indicated that human health risk analysis is important in shaping the regulations. EPA is anticipating more input. One complication is the importance of emerging toxicological assessments of the chemical constituents in CCRs (e.g., arsenic, cobalt and chromium). Because the risk is now deemed higher, some constituents have assumed new importance.

Gary D. Mooney, Sales Engineer Clyde Bergemann Delta Ducon (CBDD), discussed four viable bottom ash systems and solutions that can be retrofitted to existing power plants desiring or being required to remove an ash pond. Two systems involve replacement of the existing equipment under the boiler while two more retain the existing boiler island equipment and divert the ash slurry to new dewatering equipment. Many power plants are using wet sluices for bottom ash. The dry system has the advantage of increasing boiler efficiency if only slightly. The other systems are easier retrofits in many instances.

Patrick Garcia Strickland, Laboratory Director at Frontier GeoSciences, Inc., discussed metals mobility in coal combustion residues and analytical techniques for monitoring flyash ponds. Knowledge of the ability of metals to be released from coal combustion residues is an important factor in determining the potential effects on the environment. At the end of the presentation there was a discussion of the benefits of leaching the metals out of the flyash at the plant site. Coal –fired power plants can make 30 percent hydrochloric acid and at the same time leach metals from the flyash. The metals are captured in ion exchange resins and the purified acid is sold. This will make higher chlorine coals more attractive and result in a metal free fly ash, rare metals, hydrochloric acid and gypsum as byproducts.

According to the speakers we can expect a final rule promulgated in 2011 or 2012. The big question is “Will the final rule classify CCR as special wastes subject to regulation under Subtitle C of RCRA (Resource Conservation and Recovery Act) when destined for disposal in landfills or surface impoundments (essentially hazardous waste) or as non-hazardous wastes regulated under Subtitle D of RCRA?” If EPA decides to classify CCR as “hazardous,” under Subtitle C, EPA would create federally enforceable requirements for ash management, including waste generation, transportation and disposal. If CCR is declared non hazardous, under Subtitle D, EPA would only mandate a set of minimum national standards and leave it up to state governments and citizen litigation to enforce them.

Joshua R. More, Partner Schiff Hardin LLP, described how in working with state regulators a utility was able to close an unlined surface impoundment. Like most states, surface impoundments in Illinois are regulated under groundwater quality rules. These rules provide for protection of groundwater quality and do not specifically address design or closure standards for surface impoundments. The Illinois Environmental Protection Agency initially proposed to regulate the closure of surface impoundments under the landfill rules. However, the landfill rules were promulgated after many of the CCR impoundments in Illinois were built, specifically exclude surface impoundments and include numerous design criteria that are impractical for surface impoundments. Therefore, the utility and its legal team, supported by technical analyses from its environmental consulting team, worked with the state to develop a set of site-specific rules governing closure of a CCR impoundment. The site specific rule has become the model for closing CCR impoundments in the State of Illinois.

Mr. R. Glenn Lunger, PE, Manager Power Market at FLSmidth, Inc. Pneumatic Transport – observed that wet conveying and storage of combustion products appears to be on the brink of extinction with proposed regulation of coal combustion residuals and water usage. There are many considerations that need to be addressed in retrofitted and new dry conveying systems as utilities kick off mitigation projects. FLSmidth has been providing a number of dry pneumatic conveying solutions for combustion products for over 40 years. The costs of the conversion are likely to be only a few million dollars.

EPA Has the Ball by Tom Adams, American Coal Ash Association - Hot Topic Hour January 13, 2011
Tom Adams, Executive Director American Coal Ash Association (ACAA), explains that there is a wide range of opinion on what the impact of a hazardous waste regulation would be on the future of beneficial use of CCP. The agency believes it can exempt preferred beneficial uses from any hazardous waste regulations, and markets for those preferred beneficial uses will be unaffected, at the least, or flourish as generators will invest in technologies to make their CCP more attractive to the end users. In over eighteen months of discussions with CCP marketers, project owners, engineers and architects, contractors, material producers and other stakeholders, the ACAA has determined that the U.S. EPA is wrong in its prediction of market behavior. The stigma of association with hazardous waste regulations and potential liability exposure are primary concerns in the marketplace.

Don Kelley, Senior Scientist at Ashland Performance Materials, provided lots of examples to demonstrate that FRP made from Epoxy Vinyl Ester Resin compares favorably to acid brick-lined carbon steel, stainless steel and high alloy clad carbon steel for stack and duct applications. There has also been widespread use in scrubber vessel design. A new generation of resins provided clarity and therefore easy inspection. Derakane 510B-400 epoxy vinyl ester resin is good for 227°F and ideal for FGD. For constant operation to 275°F there is Hetron® FR998-35.

Dr. Deba Maitra, Research & Technology at Special Metals Corporation, related the results of laboratory and field testing (at a power plant in Indiana which is experiencing corrosion of 2205) which showed that while the duplex steel was severely attacked by the environment, super-austenitic stainless steel and nickel-base alloy specimens were much more resistant. The super-austenitic stainless is about half the price of C 276 and has equivalent corrosion resistance. It is being used in a new scrubber system being built in North Dakota.

National Ambient Air Quality Standard Update Colin McCall, All4 - Hot Topic Hour December 10, 2010
Within the past two years, the U.S. EPA has promulgated/proposed a 1-hour NO2 NAAQS, a 1-hour SO2 NAAQS, and a revised 8-hour ozone NAAQS. In addition, U.S. EPA has finalized new source review (NSR) regulations related to the annual and 24-hour PM2.5 NAAQS. These new health-based NAAQS are extremely stringent and will make it increasingly difficult to obtain approval for new facilities or for existing facility expansion and modernization projects.

Richard (Rich) Miller, Vice-President of Business Development for Utility Systems at ADA Environmental Solutions (ADA-ES), showed timelines which dictate that boiler operators start mercury testing soon. There are lots of unknowns due to the wide variety of fuels and boiler configurations. With the potential of large carbon needs by the utility and cement industries, supply could be an issue. Mercury reduction guarantees are going to be tough to provide since the need is a mass emission level and not a percent removal. Furthermore the 0.2 lbs/TBtu limit for biomass boilers will be difficult to measure as well as guarantee.

Robert (Bob) Fraser, Senior Technical Director at AECOM Environment, discussed AECOM’s experience to date with the boiler MACT. He indicated that no one plant is now demonstrating the ability to meet all the pollutant requirements. There is very little data on CO and dioxins. It may be necessary to install back end CO and dioxin controls. These could be quite expensive. Minimizing the time at which the gas is in the 800-460 degrees F range by quenching should be effective in avoiding dioxin formation, but this is not an option where downstream fabric filters are being operated. One big question is whether a source which switches fuels to meet the MACT would then be a “new MACT source.” If a new permit is required because of fuel switching, then it is very possible that the source would be considered “new.”

Jon Miller, Technical Support Engineer at Albemarle Corporation, explained that M-PACT is an equipment package to inject activated carbon at much lower cost than a custom design. The first M-PACT unit was sold in 2007 and is providing reliable 90 percent mercury reduction. There are a number of components in the larger systems which are critical. One is the choice of blower for the pneumatic conveying. A regenerative blower is less expensive but has a lower pressure output and is less tolerant of dirty environments. A Roots type PD blower is more expensive but capable of higher pressures and will tolerate some dust.

J. Patrick Stevens, Associate and Senior Consultant at Golder Associates Inc., told participants about a survey of 16 biomass-fired boilers in the wood products industry to determine whether or not they would meet the proposed existing source Boiler MACT limits for biomass-fired boilers. CO was one pollutant that would create a challenge. Four boilers would require no improvement. Twelve boilers will require from 13 to 79 percent reduction in CO. Nine of these would require end of pipe controls while three could improve fuel handling and combustion.

Industrial Boiler MACT: CEM Requirements by Dan Kietzer, Sick - Hot Topic Hour November 19, 2010
Dan Kietzer, Environmental Market Manager at Sick Maihak, Inc., covered CEMS for particulate and CO and CEMS requirements. The company has sold more than 50 PM CEMS using the scattered light principle to power plants in the U.S. Some were to meet consent decrees which mandated installation of PM CEMS. The scattered light approach can provide accurate mass measurement in either dry or wet stacks. In wet stacks the sample gas is withdrawn and heated prior to measurement. An insitu CEMs for CO can also measure CO2 and H2O.

David W. South, Manager of Business Development at Amerex, drew from a considerable bank of experience the company has gained with some 50 MACT related boiler installations in the last five years. One unit on a PC boiler with carbon injection and a fabric filter is using 2.2 lbs/MMacf of B-PAC. Inlet mercury is 20 lbs/TBtu versus 2.5 lbs/TBtu on the outlet. Another with only 2.0 lbs/MMacf is reducing mercury from 25 lbs/TBtu to less than 2 lbs/TBtu.

Industrial MACT Webinar - Hot Topic Hour November 18, 2010 - Part 1
Sodium Bicarbonate, Lime, CDS and Regulations were among the Topics covered on the First Day of the Industrial MACT Webinar. In 60 days or so we will know the specific changes for the final Industrial MACT. Correction-- we will know what is final until it is changed again. Unfortunately it will be three more years to find out if litigants are successful in causing changes. However, it will take three years to install the equipment and run it long enough to make sure of compliance. So it would seem there are two choices. Litigate and gamble you won’t have to shut down your plant or go ahead with the assumption that the rule will stand. Password: hth107

Mike Schantz, Director of New Business Development at Lhoist / Chemical Lime Company, explained that all hydrated lime is not the same. Sorbacal SP performs much better than typical hydrated lime on HCl. Sources using Sorbacal injection should be able to meet the 3 ppm HCl anticipated limit providing temperature, moisture, competing acid gases (SO3 and HF) and CO2 are within the normal range.

Dave Novogoratz, Business Development Manager for the Particulate Control Group at Babcock & Wilcox Power Generation Group, Inc., indicated that the requirement for PM CEMS for boilers over 250 MMBtu/hr and for CO CEMS add some new challenges. The CO limit requirements may require thermal oxidizers or CO catalyst for grate-fired units. Wet ESPs may have a place downstream of wet particulate scrubbers to meet the new PM requirements. ACI, SDA, scrubbers, fabric filters, and oxidation catalyst might be options for dioxin and furan control. Compliance will require a system solution that also takes into account other upcoming regulatory requirements.

Carroll "Mack" W. McGuffey III, Associate at Troutman Sanders LLP, told the participants that it is unlikely that the final rule will be delayed by lawsuits. The litigants can petition to stay the rule until the litigation is complete but the D.C. Circuit Court is unlikely to do so. So the clock will be ticking and compliance will be required in 2014. The lawsuits can focus on several issues. One is the lack of five or more sources achieving the limits on any one pollutant. Another is the argument that a source which achieves the limit on one pollutant but not another is not a valid example.

Yougen Kong, P.E., Ph.D., Technical Development Manager at Solvay Chemicals, Inc., explained that trona can achieve up to 98 percent HCl removal while sodium bicarbonate can achieve over 99 percent while also achieving better than 90 percent SO2 removal. There is a modest price penalty for the sodium bicarbonate. On the other hand, injection avoids major capital cost and is effective over a range of 275°F to 1500°F. Bicarbonate is being used at many waste incinerators in Europe and coal-fired power plants in the US.

Dibasic Acid from Invista for Higher SO2 Removal Efficiency
Invista DBA will be Available to Improve FGD Efficiency Rick Beatty and Gary Hilkert of Invista told a Hot Topic audience Wednesday that the Orange, Texas plant will be starting operations in the first quarter 2011 and will be able to deliver dibasic acid (DBA) to the power market. The meeting started with an overview by McIlvaine pointing out that the PM2.5 ambient rules will force states to require very low emissions of SO2 in order to reduce sulfates. Los Angeles is still struggling to meet the ambient rules even after they eliminated coal-fired power plants and major sources. The South Coast Air Quality Management District issued a new rule this month which will require refineries and several remaining sources to reduce SO2 to less than 10 tons at a cost of many millions of dollars. Note this is not 10,000,000 tons, or 10,000 tons. It is 10 tons aggregated for all sources. By contrast coal-fired boilers in the rest of the country emit 8.9 million tons. The new South Coast reduction is less than CEMS accuracy when the emissions are 10,000 tons. There is a caveat. If sources cannot buy allowances for less than $50,000/ton, then there is some relief. Welcome to the new world of PM2.5 ambient limits. DBA can substantially improve the efficiency of a limestone SO2 scrubber. In fact it can provide the equivalent of spraying an extra 20 gpm/1000 cfm of limestone slurry. So a power plant with the need to move from 92 to 95 percent SO2 removal can either add 25 percent to the pump energy input or buy an organic chemical. With greenhouse gases being of increasing concern, the increase in energy consumption is critical. DBA can minimize the efficiency reduction due to high chlorides in the recirculating scrubbing liquor. It can provide fuel and limestone purchasing flexibility. There is the potential to add to the biological oxygen demand in the wastewater but zero liquid discharge or biological treatment solves this problem. Most plants have wastewater concerns with or without DBA. DBA may improve HCl removal efficiency. Its function in dissolving the limestone should be equally effective on acid gases other than SO2. Since the Utility MACT will probably limit HCl to 3 ppm, it is likely that scrubber systems will be designed around this parameter. Invista is offering carload quantities of DBA for testing.

Zero Liquid Discharge for Power Plant Scrubbers Webinar - Hot Topic Hour November 12, 2008
On November 12, 2008, Devesh Mittal and Greg Mandigo made the case for zero liquid discharge as an alternative to the combination of physical and biological treatment. Three systems are operating at Enel plants in Italy with others under design. KCPL Iatan 2 will also use ZLD. A number of systems are already used for cooling tower blowdown. Biological systems require dilution to protect the micro organisms. Also, boron and certain other contaminants are not captured in these systems. Zero liquid discharge achieves the complete prevention of contaminants reaching the wastewater.

Dr. Santosh K. Gangwal, Manager of Business Development Energy Technology at Southern Research Institute, observed that the conversion of biomass and coal-to-liquid transportation fuels (carbon-to-liquids) can significantly improve the nation’s energy security. Biomass is a renewable resource and the United States has the world’s largest known coal reserves. Southern Research Institute’s ongoing advanced carbon-to-liquid projects were described. One display that drew the attention of everyone was the comparison of gasoline costs with various biomass and coal-to-liquids options vs. crude at two different prices. Comparison of $/bbl Gasoline Equivalent Cost (See link above to slides.) With carbon sequestration the costs increase only slightly, but this is highly site specific. Dr. Lee had actually displayed analyses for the ALE North Dakota DCL project, when using lignite the breakeven cost was only $47/bbl of crude. This is because there would be a sales value for the CO2, due to the proximity to depleted oil fields and the use in enhanced oil recovery.

Dr. Theo Lee, Ph.D., Vice President and Chief Technology Officer of Headwaters CTL, LLC, described an advanced 20,000 BPD coal-to-ultraclean liquid fuels plant that has recently been commissioned in Inner Mongolia, China. Operating since early 2009, the plant is based on Headwaters' direct coal liquefaction and Axens' synthetic fuel hydrocracker. All the process parameters have been achieved. There are some equipment issues such as the coal feed through lock hoppers instead of let down valves. Although direct coal liquefaction posts a high stringent coal requirement (prefers to use a lower coal), it is more thermally energy efficient (low carbon footprint) and requires less investment than indirect coal liquefaction. Direct liquefaction is most suitable for gasoline but can be economically tailored for production of other fuels. Indirect liquefaction allows economic production of chemicals.

Charles (Chuck) Gounaris of CoalStar Industries, Inc., discussed their process for the direct conversion of coal-to-liquid fuels. This process is more economical and environmentally-friendly than other processes currently used. A unique approach allows a minor capital investment and the production of coal crude oil. Revenues generated by the initial investment then can be used to fund the further refining. There were developments this week for several major projects. Dow and Shenhua submitted plans yesterday to the Chinese government for a coal-to-chemicals plant in Yulin, Shaanxi province. Production will be 3.3 mty of methanol, ethylene and propylene. The Baard Energy plant in Wellsville, Ohio has $2.5 billion in funding from outside investors. One crane is in place and land clearance is expected in the spring. Environmental permits have been issued after three years of litigation. Products will be diesel fuel and chemicals. The plant will employ 400 people with 4,000 used during construction.

Fabric Selection for Coal-fired Boilers Webinar - Hot Topic Hour October 28, 2010
A large group of attendees heard five very good presentations related to the selection of the best filter media to meet the various coming regulations for PM2.5. Attendees agreed that the fundamental filtration capability of the vast majority of fabrics available today, as measured by laboratory tests, far exceeds any existing or expected emission control requirement and the performance of many is below the minimum detectable limit of the test methods. Several presenters pointed out that while the results of these evaluations can be a good guide for filter efficiency and pressure drop, the actual performance of filter material will rarely achieve the levels seen in these tests. This is because the actual performance is dependent on many factors related to the specific site conditions. This causes a concern in the industry that regulators will assume that lab test results are indicative of actual performance and expect the same performance at every installation. Dr. McKenna indicated that because filter media performance was so good, future enforcement will most likely be focused on plant baghouse O&M. He also stated that it will be important to demonstrate what aspects of O&M plans are practical and valuable, so that regulators do not make these plans an operational nightmare.

Nuclear Power Plant Water Treatment Webinar - Hot Topic Hour July 1, 2010
Three industry experts provided presentations for the McIlvaine Hot Topic discussion on Nuclear Power Plant Water Treatment. • The first presentation was by Gregg Poppe of Dow Water & Process Solutions: ‘Reducing Chemicals and Waste with Advanced Water Purification Technology.’ This presentation addressed the three primary stages of effective water treatment including Pre-Treatment, Roughing, and Polishing. The importance of safe, reliable, efficient, and “green” environmentally sound practices was emphasized. Ultrafiltration using Dow tubular UF membranes was highlighted as an effective pre-treatment going into RO filtration. EDI was discussed as an effective polishing procedure that eliminates the need for chemical treatments. • The second presentation was by Timothy Rittof of Veolia Water Solutions and Technologies: ‘Nuclear Power Plant Water Treatment.’ This presentation discussed various clarification processes for non-process water including river water, reclaim (grey) water, and cooling tower blowdown water. The Actiflow and Actisoft clarifiers and softeners were discussed, along with disc filters and CeraMem filters by Veolia. Also discussed were energy recovery multi-effect-evaporators for the production of fresh water using waste heat from power plants. Veolia provides more than 40 years of experience in nuclear power plant water treatment. • The third presentation was by Anthony Rossi of GE Water & Process Technologies: ‘PWR Dispersant Review & Update, OptiSperse PWR6600.’ This presentation addressed the dispersion of iron oxides in steam generator (SG) systems using the OptiSperse polyacrylate dispersant, without any sulfates or chlorides. Testing showed very high dispersion activity with very low polyacrylate dosages. The effectiveness of the treatment at reducing corrosion, and thermo-hydraulic instabilities was discussed. Advantages include improved long-term thermal performance of the SG, potential for long-term reduction in routine off-line cleaning frequency, and the long-term goal of a reduction in frequency or complete avoidance of full bundle SG chemical cleaning.

Catalyst Selection for Coal-fired Power Plants Webinar - Hot Topic October 21, 2010
Experts representing consulting, catalyst, regeneration, and systems companies provided an indepth analysis of the latest trends in catalyst use in coal-fired power plants. The dominant theme was that the SCR is no longer just a NOx removal device but is a multi-pollutant control device. Various alternatives for increasing performance and decreasing cost were proposed. Some involved maintenance of the existing catalyst while others emphasized better designs which last longer without maintenance and can thereby minimize or eliminate the maintenance. There was also discussion on how the various designs compare. The claim was made that hydraulic diameter was a better measure than pitch. There was agreement that it would be desirable to define various terms relative to maintenance of catalysts. The consensus seemed to be as follows: CATALYST Management 1. Maintenance a. Cleaning b. Rejuvenation c. Regeneration 2. Replacement Cleaning Catalyst: a dry process such as vacuum or mechanical removal of accumulations Rejuvenation Catalyst: wet chemical removal of accumulations Regeneration Catalyst: wet chemical removal plus re-impregnation of catalytic compounds Physical characteristics 1. Geometry a. Catalyst shape 1. Honeycomb 2. Corrugated 3. Plate b. Openings 1. Pitch 2. Hydraulic diameter Hydraulic diameter: The hydraulic diameter, DH, is a commonly used term when handling flow in noncircular tubes and channels. Using this term one can calculate many things in the same way as for a round tube. Definition: DH =4A P where A is the cross sectional area and P is the wetted perimeter of the cross-section. Reference http://en.wikipedia.org/wiki/Hydraulic_diameter McIlvaine solicits the input from subscribers as to the appropriate nature of this classification.

Advances in catalyst design will help address various pollution control issues but will also increase the number of parameters which must be evaluated during catalyst specification and selection. Plants are switching to high sulfur coals thus increasing SO3. Mercury control requires new catalyst design. The catalyst regeneration option offers potential cost savings but adds another performance variable.

Diagram: Expansion Joint Placement for Coal Fired Power Plants
Diagram showing expansion joint placement in a coal fired power plant. The power plant can be subdivided into hot and cold areas. On the hot side, the temperature load and the loading of the flue gas with fly ash is decisive. On the cold side, the expansion joint is primarily affected by the formation of aggressive condensate due to temperature falling below the dew point.

Michael T. Rossler, Manager of Environmental Programs at the Edison Electric Institute, says the Utility MACT could cost the industry $200/billion/yr by 2015. He provided timelines. The rule will be proposed by March 16 and finalized by November 16, 2011. This will not replace mercury rules already issued by 20 States. The industrial boiler MACT as proposed offers a prelude. It proposes limits for mercury, dioxin, PM (as a surrogate for non-mercury metals, HCl (surrogate for acid gases) and CO (surrogate for non-dioxin organic toxics). Other rules on water, waste and carbon need to be coordinated with this rule in fairness to the industry.

Robert (Bob) Fraser, QEP, a Senior Technical Director for Power Generation Services within AECOM Environment, believes the proposed Boiler MACT is a prequel to the Utility MACT. Since the best utility units are better controlled than their industrial counterparts he expects a more stringent utility rule. If low CO levels are required because CO is a surrogate for organic HAPs then there may be a problem meeting NOx limits. Oxidation catalysts have not been proven for solid fuel applications with the possible exception of the Babcock regenerative catalyst for wood-fired boilers. Incinerators control dioxins using ACI, but with lower quantities of dioxinsit may be hard for the utility industry to achieve comparable percent efficiencies.

Carrie Yonley, P.E., Vice President at Schreiber, Yonley & Associates, alerted participants to the fact that the Cement MACT was published on September 9 in the Federal Register. It is indicative as to the likely content of utility rules. The industry is also facing the CISWI final rule slated for December. If the kiln burns solid waste then it may be subject to this rule. For existing kilns the Cement MACT particulate limit will be 0.04lb/ton of clinker. This is 0.004 gr/dscf. This compares to the previous limit on new kilns which was 10 times higher. PM CEMs will be required to determine compliance. CEMs will also be needed for Hg and THC. An HCl CEMs will be needed only if a wet scrubber is not used. But the units will have to comply with an HCl limit of 3 ppm based on a 30 day rolling average and 7 day rolling average for startup and shutdown operations

Zero Liquid Discharge for Power Plant Scrubbers - Hot Topic Hour November 12, 2008
On November 12, 2008, Devesh Mittal and Greg Mandigo made the case for zero liquid discharge as an alternative to the combination of physical and biological treatment. Three systems are operating at Enel plants in Italy with others under design. KCPL Iatan 2 will also use ZLD. A number of systems are already used for cooling tower blowdown. Biological systems require dilution to protect the micro organisms. Also, boron and certain other contaminants are not captured in these systems. Zero liquid discharge achieves the complete prevention of contaminants reaching the wastewater.

Integrated Approach to Mercury Control for Low Sulfur Coals Webinar - Hot Topic Hour May 14, 2007
Mercury from low sulfur coal burning plants can be cost effectively reduced by utilization of combustion optimization, particulate control and sorbent injection. Sorbent usage is minimized. Experience has also been achieved with the addition of biomass to the coal. A hybrid Max 9 collector at 90 MW is operating effectively with substantial mercury reduction in a pulp mill where the fuel is 90% coal and 10% biomass. Combustion optimization is achieved with biomass as either a co-fired or reburn fuel. GE is making quotations and is prepared to deal with the stringent timelines facing utilities in many States.

MPW optimizing CO and NOx with Emerson SmartProcess
MPW entered into a contract with Emerson Process Management Power and Water Solutions to provide an Emerson SmartProcess Combustion Optimization System for Muscatine Units 8 and 9 which would help reduce emissions and find the optimum positions for various parameters in the boiler combustion process Two parameters carried the highest weights in the combustion optimization system with the CO weight being about double the NOx rate which was targeted around 110 ppm with variations dependent on load. During execution of the optimization project and the first few months of operation with the CO analyzer in-service, both MPW and Emerson agreed that the most important parameter in the combustion process was CO and that it should be maintained at or below 50 ppm and if the CO limit got exceeded in the combustion process, more weight would be given to CO sacrificing NOx somewhat. However, this situation never arose during and after the project was completed. It should be noted that other than the combustion optimizer, there are no other systems post-combustion that would reduce CO. Thus, the weighting was setup to have the CO control variable carry the highest weight and NOx, the second highest. The system was satisfactorily put into operation in 2008
