Abstract

The rectification of water–ammonia condensate obtained in the removal of ammonia from coke oven gas by a circulatory process is studied. In processing condensate containing acidic impurities (carbon dioxide, hydrogen sulfide, hydrogen cyanide) and organic components of coke oven gas, rectification conditions yielding liquid ammonia that is free of moisture and impurities are established.
