Real time corrosion monitoring for HRSG
Flow accelerated corrosion (FAC) can cause iron loss in steam piping and lead to lethal accidents. As a result, programs are necessary to reduce metal loss and to monitor the loss which does occur. A team from Danaher analyzed the problem in a Power Engineering article earlier this year.

$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.

Discussed many of the monitoring problems. He believes that FTIR in situ, cross duct is the best measurement option for ammonia. Controlled condensation is the best manual method for SO3 measurement. FTIR using Quantum Cascade Laser in situ cross duct technology is the best continuous method for SO3 measurement.

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.

Beneficial Byproducts of Coal Combustion and Gasification Webinar - April 28, 2011
A good discussion yesterday, April 28, 2011, covered flyash and FGD byproducts. One of the conclusions is that depending on the fuel and the proximity to byproduct users, there are attractive alternatives to limestone scrubbing. Another conclusion is that the disposal of any solids from power plants will be under greater scrutiny in the future
