Abstract
PURPOSE: To remove SOx from exhaust gas with high desulfurization ratio without bing accompanied with NH3 emission, by contact of the exhaust gas contg. SOx with a soln. of ammonium sulfate and ammonium sulfate and ammonia produced in the presence of O2, and by final contact with soln. of ammonium sulfate, which has been made acidic with sulfuric acid and is ranging in pH 4.5-3.5.
