ABSTRACT:
A method and apparatus for deodorizing waste gases containing foul-smelling constituents that are chemically decomposable on being washed with aqueous acid formed by dissolving an acid-forming gas, such as chlorine or sulphur, in water and wherein the waste gas is washed with the aqueous acid containing a suspension of one or more alkaline earth metal carbonates, such as magnesium carbonate or calcium carbonate. In a vessel, the carbonate suspension may be sprayed downward at the top, and the waste gases directed upwardly at the bottom. Both the suspension and the gases pass through loose layers of limestone intermediate the top and bottom of the vessel.
