SCR - The Selective Catalytic Reduction process (SCR) is used when the flue gas temperature is too low for the chemical reactions to occur spontaneously, and a catalyst is needed to accelerate the reduction process. In order to reach high NOx reductions efficiency, the reagent must be mixed very uniformly before entering the catalyst.
