FIELD: chemistry.
SUBSTANCE: invention can be used in chemical industry. Gas mixture is supplied into high-pressure region 1 through bubbler 5, dipped into absorbent layer 4. Separating disc keeps formed bubbles of gas mixture in absorbent layer while they move from the centre to the periphery to the exit of high-pressure cavity 1. Ammonia, well-dissolved in absorbent 4, diffuses through membrane 3 into cavity of low pressure 2, and partially soluble components are withdrawn from high-pressure cavity.
EFFECT: application of claimed invention makes it possible to increase selectivity of ammonia separation from gas mixtures.
