It involves the conversion of nitrogen oxides (NOx) into atmospheric nitrogen and water vapour through using diesel exhaust fluids as a catalyst. SCR is one of the most effective ways of reducing NOx in a flue gas stream, with reductions up to 95%. Selective Catalytic Reduction (SCR) is a proven and advanced active emissions control technology system that injects a liquid-reductant agent through a special catalyst into the exhaust stream of a diesel engine. UPSC Syllabus. Here you can find the meaning of Which of the following mechanisms can be used for reducing the emissions from thermal power plants? The amount of ammonia required for a SCR system is just over 1:1 mole ratio of NOx to be reduced. Selective Catalytic Reduction is capable of reducing NOx emissions by 90% while also reducing HC and CO emissions by 50-90%, and particulate matter (PM) emissions by 30-50%. Adblue Fluid used in Diesel Cars is explained in this video.
