Abstract
A process for removing NO.sub.x oxides and SO.sub.x oxides from gaseous streams contacts the gaseous stream with an aqueous solution of chloric acid. The process of the invention removes sulfur oxides and nitrogen oxides from waste gas streams without producing inorganic salts. In addition, the use of chloric acid provides improved oxidation of NO and SO.sub.2. The process can be operated to treat 'dirty' gas streams containing particulates and compounds which may poison or contaminate NO.sub.x removal systems employing catalysts.
