Abstract
A method of removing ammonia from a waste gas mixture containing ammonia, air, and water vapor, and having a first treatment zone containing a body of water and a second treatment zone in flow communication with said first flow zone. treatment; characterized in that it comprises the operations of: (a) maintaining said first treatment zone and said body of water at a predetermined cold temperature; (b) bubbling said residual gas mixture upwardly through said first treatment zone and said body of water to dissolve a first amount of ammonia from said mixture in said body of water; (c) circulating said residual gas mixture to said second treatment zone; (d) exposing said residual gas mixture to a countercurrent flow of water droplets in said second treatment zone to dissolve a second quantity of ammonia from said mixture, said water droplets circulating with said second quantity of ammonia towards said mass of Water; (e) separating said residual gas mixture from said second treatment zone; (f) continuously separating a part of said body of water containing said first and second dissolved amounts of ammonia as a product; (g) measuring the percentage of the ammonia content in said product; and (h) recirculating said product back to said first and second treatment zones until said product from said measurement operation reaches a predetermined ammonia content.
