Abstract

The scrubbing of a boiler exhaust gas stream to remove pollutants comprising one or more of the acidic oxides of sulphur, nitrogen, carbon and compounds of any of the halogens is effected by contacting with a solution derived from dissolving in water the soluble components of boiler ash containing as solids one or more of alkali and alkaline earth metal salts to produce a basic (pH grader than 7) solution. The pollutants react with the water therein to produce acids. The latter react with any oxides, hydroxides and carbonates of alkali and alkaline earth metal salts and anionic salt components, namely, carbonate, sulphate, sulphite, nitrate and nitrite, and compounds of the halogens, along with a precipitate of alkali and alkaline earth metal salts with any insoluble components of the ash.
