Abstract

FIELD: gas purification. SUBSTANCE: invention relates to technique of adsorption separation of gas mixtures allowing elimination of product deterioration in case of technological regime irregularities and consists in that gas mixture is passed through adsorbent layer producing a product enriched in one component followed by adsorbent layer recovery producing another product enriched in other component. Make-up of the two products is continuously monitored, and, in case of any deviation of component concentrations from specified values, switching to corresponding operation stage is followed. EFFECT: increased reliability of process.
