| description | A method for recovering ammonia and organic compounds from offgases contaminated with organic materials, carbon dioxide, and ammonia, using a combined absorption and rectification column is disclosed. Carbon dioxide is washed out with aqueous alkali, ammonia is drawn off as an overhead product, and the organic compounds are recovered in pure form from the bottoms product following separation-out of the alkali carbonate. |
