Custom Designed Selective Catalytic Reduction (SCR) Systems

Selective catalytic reduction (SCR) is a means of converting nitrogen oxides, also referred to as NOx with the aid of a catalyst into diatomic nitrogen, N2, and water, H2O. A gaseous reductant is added to a stream of flue or exhaust gas and is absorbed on to a catalyst.

Commercial selective catalytic reduction systems are typically found on large utility boilers, industrial boilers, and municipal solid waste boilers and have been shown to reduce NOx by 70-95%. More recent applications include diesel engines, such as those found on large ships, diesel locomotives, gas turbines, and even automobiles.

CTi Controltech manufactures custom SCR systems and would be glad to discuss your requirements.
