FIELD: process engineering.
SUBSTANCE: invention relates to separation of gas mixes by short-cycle unheated adsorption. Gas mix flow is subjected to compression in compressor and forced cyclically through adsorbent layer in two parallel jointed adsorption columns wherein pressure increase and decrease conditions are sequentially maintained. Said conditions are maintenance using synchronous switching of inlet valves. Outcoming product flows forced from increased pressure column via said outlet valves into high-pressure membrane gas separator for said product to be enriched and fed to using equipment. Product residual flow is fed from membrane apparatus via aforesaid valves for blowing adsorption low-pressure column at low pressure. Receiver shut off in one direction by check valve is used to stabilise operation of membrane apparatus.
EFFECT: higher efficiency and degree of extraction of target components.
