Abstract

Procedure for removing nitrogen oxides and sulfur oxides from a gas, consisting of the steps of, first, adding chlorine dioxide or ozone gas to the waste gas, whereby the nitrogen monoxide contained in said waste gas becomes nitrogen dioxide and/or dinitrogen trioxide; and, second, contacting the exhaust gas with an aqueous purifying solution having a ph of not less than 6 and containing at least 1% by weight, based on the total weight of the purifying solution, of sulfite. Alkali or ammonium sulphite, in a purifying column, to purify the sulfur oxides and nitrogen oxides contained in the waste gas. (Machine-translation by Google Translate, not legally binding)
