Abstract
Disclosed herein is a process and a plant for recovering ammonia from a mixture including ammonia, acid gas containing HS and/or COand low-boiling water-soluble organic components. To avoid an enrichment of volatile organic compounds in the acid gas absorber, a partial stream of the liquid phase is withdrawn from an acid gas absorber and processed such that gaseous ammonia with a reduced content of volatile organic components is obtained, which is recirculated into the acid gas absorber.
