SCR - Selective Catalytic Reduction
NOx emissions are the product of every air-fed combustion process and are known to contribute to acid rain, forest and vegetation decline, changes to the ozone layer and greenhouse gases. The EPA and other governing agencies mandate the reduction and control of NOx emissions through permitting.
Ammonia is used in a de-nitrification process converting NOx into free nitrogen and water vapor through catalytic (SCR) and non-catalytic (SNCR) applications.
