The Low Dust Selective Catalytic Reduction (SCR) System is a comprehensive process designed to achieve reduced emissions of nitrogen oxides (NOx). It involves several steps, beginning with the introduction of a lean reagent which is injected upstream of the Selective Catalytic Reactor in order to react with NOx gases and reduce their emissions. This is followed by two or three additional stages involving the passing of exhaust gases through heat exchangers and catalysts before emission into the atmosphere.
