WebbSelective catalytic reduction (SCR) is a technology used to reduce the level of nitrogen oxides (NOx) in the presence of a catalyst. Vaporized reagent (Ammonia or Urea) is injected into flue gas and reacts with NOx on the SCR catalyst resulting in nitrogen (N 2) and water (H 2 O). NO 2 + NO + 2 NH 3 ↔ 2 N 2 + 3 H 2 O WebbUltimately, SCR proved to be a more robust emission technology than the main alternative option, NOx adsorbers, and has been widely used in all types of mobile diesel engines. …

WebbSelective Catalytic Reduction (SCR) technology reduces emissions of oxides of nitrogen (NOx) by using a catalyst. SCR technology can achieve a reduction of up to 95 % of NOx in the combustion process and can thus meet the more stringent future legislation.
