Effluent treatment by selective catalytic reduction (SCR)We explain the treatment of effluents by selective catalytic reduction to eliminate NOx and SO₂ with 90% efficiency for industrial processes.Selective catalytic reduction (SCR)The process of selective catalytic reduction (SCR) is based on reduction of NOx with NH3 in the presence of excess O2 and an appropriate catalyst. Thus transforming it into harmless substances such as water and nitrogen. Ammonia, in the form of liquid ammonium hydroxide, is vaporized, diluted with air and injected directly into the stream […]
