Fossil Fuel-fired Power Plants can be a Positive rather than A Negative
Contributor to Water Quality
Operators of coal-fired power plants and gas turbine combined cycle power plants
can utilize municipal wastewater for cooling and other needs. When they also
eliminate discharges through zero liquid discharge (ZLD) technology they become
positive rather than negative contributors to water quality. Water lost
through evaporation can be greatly reduced by heat extraction from the flue gas
before it reaches the scrubber. This also reduces total CO2/MW and
makes the plant greener in every sense.
The markets and technology for this approach will be discussed in a free webinar
on February 25th at 10:00 a.m. CST.
The various geographical markets will be analyzed. China is embracing ZLD in
its power plants as well as its coal-to-chemical facilities. Gas
turbine combined cycle power plant developers in the U.S. are selecting ZLD not
only in arid areas but generally to avoid the need to obtain water discharge
permits. ZLD is the preferred option in Saudi Arabia and surrounding
countries.
The availability and cost of treated municipal wastewater will be reviewed.
In general, power plants are near enough to municipal treatment plants to make
the use practical.
Technologies to minimize evaporation losses will also be discussed. The
potential is being increased by new developments such as catalytic filtration at
850oF.
China is making the largest investment in ZLD.
Huaneng Group, China’s largest power producer, has constructed a 1.3 GW
state-of-the-art ultra-supercritical coal-fired power plant at the Changxing
Power Station in Zhejiang Province.
•The plant uses Oasys’ technology to treat the wastewater from flue gas
desulfurization (FGD).
•The system treats up to 650 cubic meters of wastewater a day. Startup was early
2015. The system uses forward osmosis separation technology.
Aquatech has supplied ZLD systems for a number of power plants and
coal-to-chemicals plants. Enel has
purchased several systems from Aquatech for its Italian coal-fired power plants.
Aquatech has a Zero Liquid Discharge (ZLD) plant in a coal-to-chemicals
facility in Inner Mongolia. The ZLD plant incorporates HERO™ (High Efficiency
Reverse Osmosis) and a Thermal Brine Concentrator. The plant will treat 2400 m3/day
of wastewater and reuse 92.5 percent of it, producing 2000 m3/day of
process water and 220 m3/day of distilled water for various end user
applications.
China has some ZLD systems using evaporators but is leaning toward the cheaper
route of using flue gas to evaporate liquid in the sludge. The spray drier
approach is being offered by Mitsubishi, URS and other international companies.
The various approaches for evaporation of water from slurries will be analyzed.
One option is a falling film evaporator (inside the brine concentrator vessel)
that is seeded with calcium sulfate to minimize scale formation.
Mechanical
vapor recompression (MVR) is the method by which a blower, compressor or jet
ejector is used to compress, and thus, increase the temperature of the vapor
produced. In this way, the vapor
can serve as the heating medium for the ZLD solution being concentrated. The
efficiency and feasibility of this process lies
in the efficiency of the blower or compressor and the heat transfer co-efficient
attained in the heat exchanger contacting the condensing vapor and the
boiling ZLD liquid. Several different blower and compressor options will be
reviewed.
The discussion will also include the co-combustion of sewage sludge and the use
of gasified sludges as reburn fuels in coal-fired boilers.

Israel Approves Natural Gas Exports to Egypt
Israel's government has given the go ahead to begin exporting natural gas to
Egypt, signaling a potential improvement in relations between two countries
which have been at loggerheads over energy supplies.
Chile's ENAP, Japan's Mitsui to Partner on $3.1 Bln Natural Gas Generation (08)
Chile's state oil company ENAP said on December 23 that it has inked an
agreement with Japan's Mitsui & Co to develop two natural gas power generation
projects that will have a combined installed capacity of some 1,200 megawatts.
Investment in both projects that will be developed in Chile will total around
$1.3 billion ENAP said. In late October, ENAP's chief executive Marcelo Tokman
told Reuters that the state-owned company was aiming to pick a strategic partner
before year end to develop natural gas power generation projects.
Nigeria's NNPC Issues 2016 Crude Oil Contracts worth $13.5 Bln (08)
Nigeria's NNPC has issued its 2016 crude oil term contracts to 21 companies,
going directly to international refineries, trading houses and local downstream
firms, according to a list obtained by Reuters. The contracts cover 991,000
barrels per day (bpd) of oil, worth $13.5 billion at current crude oil prices,
which is roughly half of Nigeria's crude oil production of just under 2 million
bpd. The list includes refiners such as Spain's Cepsa, Italy's Saras, India's
IOC and ENOC of the Emirates, as well as trading houses Trafigura, Mercuria and
Vitol and international oil companies ENI, Total, Exxon and Shell. The remainder
are Nigerian downstream and NNPC trading companies. The list is pared down from
the final 2015 contract list, which comprised 43 companies and did not include
any global traders.
UK's Coryton Oil Storage to Open in 2016 with Global Glut Boost
The Thames Oilport terminal near London will open next spring, its operator
Greenergy said on December 21, as a rising glut in oil supplies has made storage
one of the industry's most attractive investments.
Finland and Estonia to Start Planning Gas Pipeline (06, T17)
The European Commission, Finland and Estonia signed a deal on December 22 to
start planning for a gas pipeline between the two countries, the Finnish
government said. The pipeline, called Balticconnector, will improve energy
security in Finland, which now totally depends on pipeline gas imports from
Russia, he added. The Commission and the two countries have signed an agreement
on a 5.4 million euros grant for studies needed to launch construction works of
the undersea gas pipeline across the Gulf of Finland. European Commissioner for
Climate Action and Energy Miguel Arias Canete said the deal marked an important
step for connecting the gas markets of the eastern Baltic Sea region with the
rest of the EU. Finland and Estonia agreed in October to submit a joint funding
application for a pipeline estimated to cost 250 million euros, and expects it
to be built by 2019. The pipeline will allow the transportation of gas in both
directions and, together with a planned gas link from Lithuania to Poland, will
help end the isolation of the Finnish gas market, the Commission said in a
statement. Once completed, the two links will allow Finland and the Baltic
states to diversify their gas sources and deal with any potential supply
shortages in the future, it added. While the Baltic States have access to global
liquefied natural gas (LNG) markets via an import terminal opened in Lithuania
last year, Finland remains an isolated market. The Polish-Lithuanian link is
planned to start operations by end-2019.
Thai PTT Plans to Invest $8.2 Bln over the Next Five Years (08)
Thailand's biggest energy firm PTT Pcl plans to spend 297 billion baht ($8.2
billion) over the next five years, mainly on building infrastructure such as
natural gas pipelines, its chief executive said on December 25. The board has
approved the five-year investment plan, which does not include a budget for
potential acquisitions, Tevin Vongvanich said. The investment budget for next
year is 50.8 billion baht, he added, broadly similar to the company's 2015
spending of about 50 billion baht. "Over the next three years, the volumes of
oil and gas will be lower in line with a fall in oil prices while demand will
continue to grow," he said. "There will be oversupply until 2017," he added.
Domestic demand for energy is expected to increase by 2 percent next year, with
Thai GDP growth seen at 3.7 percent next year - up from 2.8-3.0 percent this
year, the CEO said. PTT's core subsidiaries include PTT Exploration and
Production, PTT Global Chemical and Thai Oil.
Argentina Signs $500 Mln Gas Production Deal with Dow Chemical (07, T16)
Argentina's state-run energy company YPF said on December 15 it has entered a
$500 million joint venture with Dow Chemical to drill for natural gas next year
in the Vaca Muerta shale formation in Patagonia. A spokesman for the company
said the investment will be split evenly between Dow and YPF during 2016.
Production will come from Vaca Muerta's El Orejano field. "By the end of 2016,
production at El Orejano could triple to reach an average 2 million cubic meters
per day," YPF statement said, adding that the investment comes atop an earlier
$350 million joint venture between the two companies. YPF estimates the Vaca
Muerta deposit contains 661 billion barrels of oil and 1,181 trillion cubic feet
of natural gas, making it one of the biggest shale reserves in the western
hemisphere.
CB&I to Provide Construction Services for Lake Charles MEG Plant (07, T17)
CB&I announced on December 21 it has been awarded a contract valued in excess of
$365 million by Lotte Chemical Louisiana, LLC to provide construction services
for a monoethylene glycol (MEG) facility in Lake Charles, Louisiana. The MEG
facility will be located adjacent to the ethane cracker, as announced by a joint
venture between Axiall Corporation and Lotte Chemical Corporation. "This project
is the second of two important petrochemical initiatives Lotte Chemical is
developing in the region, and CB&I is pleased to have been selected for both
projects," said Philip K. Asherman, CB&I's President and Chief Executive Officer
China Sets CO2 Reporting Standards Ahead of Market Launch
China issued national standards for industrial firms to report their greenhouse
gas emissions as part of the country's plan to launch a national carbon market
in 2017. The new standards, issued by the National Development and Reform
Commission (NDRC) on December 23, will enable the China to create a statistical
system for greenhouse gas emissions and support the establishment of a national
carbon trading scheme.
New LNG Supply to Create Structural Changes in Asia-Pacific Gas Market
Last month, Goldman Sachs cut its forecast for next year's liquefied natural gas
(LNG) prices in Asia by 13 percent, stating that LNG prices will likely drop a
further 23 percent by 2018.
China's Record Fuel Exports Are Bearish for Oil Markets
It's tempting to view the growth in China's crude oil imports this year as
mainly a result of increased strategic stockpiling, but that overlooks the
rising importance of refined product exports. The stockpiling matters to crude
oil markets as every barrel put into storage is ultimately positive for demand,
as that barrel is effectively consumed insofar as it is taken out of the market.
However, every barrel refined in China and exported as fuel is simply a barrel
that isn't bought elsewhere, as Chinese exports compete and replace fuel
produced in other refining centers, such as India, Singapore and the Middle
East.

Innovations Changing the Industrial Scrubber Industry
End users and suppliers are both challenged to keep up with the rapid
developments in particulate scrubbing, gas absorption, gas adsorption, dry
scrubbing, condensation separation and biofiltration in industrial processes
such as iron and steel, cement, waste-to-energy, natural gas treatment and
sewage sludge incineration (scrubbers in coal-fired power are analyzed
separately).
The drivers behind this rapid pace are regulations and innovations. The
regulations in one country soon are copied in others. The innovations in
one industry are eventually embraced by other industries but not as quickly as
they should be. It is highly
desirable to continually determine how the successes in one application can be
applied to others.
Regulations:
Foundry cupolas, BOF furnaces, and waste-to-energy plants can no longer rely on
particulate scrubbers to meet the stringent emission standards.
Instead fabric filters are the leading choice. This has led to the
development of dry scrubbers which can be used in combination with fabric
filters. So the dry scrubber
segment has grown robustly while the particulate scrubber segment has stagnated.
However, even newer regulations identifying condensibles as a component of total
particulate has opened the door to the wet approach.
Regulations addressing liquid and solid waste have favored dry scrubbing.
However, some new wet approaches resulting in usable byproducts have caused
growth in the wet scrubbing segment.
Condensation scrubbing is a growing segment thanks to the concern with
greenhouse gases and the potential for extracting heat from exhaust gases.
Innovations:
The air pollution control systems in waste-to-energy plants in Europe
incorporate a number of innovations.
Four stages of scrubbing result in hydrochloric acid, gypsum, precious
metals, salable ash and capture of the exhaust gas heat.
The development of highly reactive lime particles coupled with catalytic filters
allow acid gas, NOx and particulate removal at 850°F.
The heat from the clean gas is then easily extracted.
Glass furnaces, biomass combustors and other sources have embraced this
technology.
There are innovative ways to remove mercury. The non-ferrous
smelting industry is using unique chemistry in wet absorbers. A number of
sewage sludge incinerator operators in the U.S. have incorporated mercury
adsorber modules into their scrubbers. The modules can handle
the wet gas leaving the mist eliminators.
Membrane contactors are proving to be an improvement for separating gases such
as CO2 and H2S.
The cutting edge technology is ionic liquids being used in mercury removal from
natural gas. This promises to have wider application for pollutant removal
in many combustion sources.
A gas bubble encapsulation technology is still in the pilot stage but the
conversion of the gas stream into bubbles one-thirtieth of one inch in
diameter creates mass transfer surfaces thousands of times greater than packed
towers on plate columns. The problem is the physical separation of the gas and
liquid components after the absorption takes place. The company which
solves this problem will change not only pollution control but many chemical
processes.
The venturi scrubber which has been rejected for particulate scrubbing, may find
a revival as a critical component of rare earth recovery from flyash. It
can capture both HCl and particulate and start the leaching process of the rare
earths all in one step. Additional
particulate removal then takes place in wet precipitators.
McIlvaine is conducting cross pollination webinars.
Decision guides in a number of industries are displayed and discussions
regarding wider use of innovations encouraged. These discussions are free to
everyone. The decision guides are included in the following two services:
