WebJul 16, 2024 · SCR (Selective Catalytic Reduction) is a method to reduce NOx emissions by converting the NOx to Nitrogen (N 2) and water (H 2 0) by the reaction of NOx and Ammonia (NH 3 ). This reaction is sometimes referred to as De-NOx. The reaction between NOx and NH 3 is never perfect, although it can achieve efficiency rates often higher than 95%.
