Abstract

A process for separating ammonia from an ammonia-containing gas mixture (1') by mixing the gas mixture with an aqueous liquid by which ammonia is at least partly absorbed, wherein the gas mixture and the aqueous liquid (14) are separately introduced into the inlet hood (15) of a tube bundle heat exchanger (16) and are mixed therein to obtain a two-phase gas-liquid mixture, wherein subsequently the gas-liquid mixture is passed through the tubes of the tube bundle heat exchanger (16), wherein the gas-liquid mixture is cooled by a cooling medium guided on the shell side, the gas-liquid mixture from the heat exchanger (16) subsequently is transferred into a separator (18) for separating the gas and liquid phases, wherein a gas phase (19) depleted of ammonia and a liquid phase (12') enriched in ammonia are obtained and each discharged from the separator (18) for the further use.
