Purchases of NOx Control Systems and Catalyst to Exceed $12 Billion This Year

Power generators and industrial facilities will spend $12.8 billion for NOx control systems and replacement catalyst in 2013. Thanks to the decision of the Chinese government to retrofit 400,000 MW of existing power plants and add 250,000 MW of new power plants with SCR in the next five years, the market will continue to grow. This is the conclusion reached in NOx Control World Markets published by the McIlvaine Company.

Most of the present revenues and most of the growth will be in the coal-fired sector. This is despite the increasing use of SCR on gas turbines. Coal will be the fuel of choice for new power plants in Asia. Even though many gas turbine generators will be installed in the U.S. and Europe, their capacity will not equal that of the new coal-fired power plants installed in Asia.

Furthermore, the cost of the SCR systems for gas turbines is less than for coal-fired boilers. The catalyst also lasts nearly twice as long as the catalyst in coal-fired power plants. However, the total air treatment for gas turbines includes filtration and treatment of inlet air plus not only NOx but also CO reduction in the exhaust gas. So the total gas turbine air treatment market is a sizable $10 billion per year.

For coal-fired power plants anhydrous ammonia is the most popular reagent. Systems which convert urea to ammonia are also popular. For gas turbines aqueous ammonia is the reagent of choice. Even though the cost is higher for this dilute solution, the total amount of reagent required is much lower for gas turbines than for coal-fired power plants. So the higher consumables cost is offset by the capital reduction and the lower safety risks.
