Abstract

1370678 Effluent purification E I DU PONT DE NEMOURS & CO 21 Dec 1971 [21 Dec 1970 8 March 1971] 59415/71 Heading C1A Oxidizable gas is removed from a gas stream by washing with an aqueous acidic solution comprising hydrogen peroxide or a reaction product thereof (as defined) in a washing zone, adding fresh hydrogen peroxide to at least a portion of the washing solution thereby reactivating it and recycling the reactivated solution to the washing zone. The term "reaction product thereof" means a peroxyacid which may be generated in the system by hydrogen peroxide. The effluent gas stream may be a stack gas from a generating station, smelter off-gas, oil-refining off-gas or off-gas from a sulphuric acid, nitric acid or coke plant or from refuse burning. Acidic impurities which may be removed include SO2, NO, CO and H2S. The scrubbing tower may be packed in any conventional manner. The fresh hydrogen peroxide should be free from traces of persulphuric acid. Suitable acids which may be used in the washing solution include sulphuric, nitric, hydrochloric, phosphoric, acetic, formic and carbonic and mixtures thereof. The acid concentration may vary from 1 to 85% by weight.
