NOx Control Market to Exceed $5.7 Billion This Year

The market for selective catalytic reduction systems (SCR) and for the catalyst used in these systems will exceed $5.7 billion this year. This is the latest forecast in the continually updated NOx Control: World Markets published by the McIlvaine Company.

This forecast does not include any mobile sources but does include stationary engines, coal-fired boilers, gas turbines, cement plants and other industrial sources.

The market can be further segmented into $4.3 billion for systems and $1.5 billion for replacement catalyst. The equipment market is volatile due to the large size of coal-fired power plant orders. The catalyst sales are steadily growing due to the lack of retirements of existing systems and the need to substitute new catalyst for existing catalyst every 3 to 5 years.

The rapid growth continent is Asia. China will install an average of 35,000 MW of new coal-fired boilers each year. Most of these will be equipped with SCR. This is in addition to a substantial program to retrofit SCR to older units.

The large number of gas turbine power plants scheduled for the U.S. will boost the NOx control market in this country. Some of these units will be peaking rather than combined cycle and will require high temperature catalyst or system designs to cool the flue gas to temperatures suitable for a lower temperature catalyst.
