FIELD: process engineering.
SUBSTANCE: method of simultaneous extraction of ammonia from blowdown and tank gases composed of ammonia (0.1 to 12 % by weight), hydrogen (15 to 58 % by weight) and other gases (making the rest), comprises separate flushing in scrubbers and common stage of ammonia condensation and drying. Flushing is performed in multistage scrubbers wherein ammonia solutions are cooled between absorption stages. Note that ammonia is extracted after first stage of every scrubber by evaporating ammonia solution fed at equal pressure in common volumetric or film-type apparatus after each solution expands in hydraulic turbine.
EFFECT: improved economic and ecological properties.
