Selective Catalytic Reduction (SCR) is the process of NOx reduction, or DeNOx, that occurs when a NOx source is mixed with ammonia and allowed to react at the surface of a catalyst.
The liquid ammonia injected upstream turns into gas, mixes with the NOx gas, and the mixture reacts at the catalyst. The result is conversion to nitrogen gas N2 and water vapor H2O, both harmless constituents of the atmosphere. While the process uses aqueous ammonia, there is no wet residue or by-product. All the reactants leave the system as gases.
Tri-Mer offers three DeNOx approaches:
DeNOx efficiencies over 90% can be achieved. Tri-Mer integrated SCR systems, whether filter based or stand-along catalytic reactor, include ammonia injection and storage tanks. For smaller applications, 300 gallon totes of aqueous ammonia are suitable.
