MEMBRANE SEPARATION OF GASES

摘要

FIELD: technological processes. ^ SUBSTANCE: present invention may be used for separation of CO2 from liquids in chemical, petrochemical and other industries. Liquid enriched with carbon dioxide under higher pressure is brought in contact with membrane on the basis of polyacetylene substituted with trimethylsilyl groups. Difference of pressures at membrane makes at least 1 bar. Some CO2 is transferred from liquid via membrane, at the same time membrane remains impermeable for absorbing liquid. ^ EFFECT: improved efficiency of CO2 separation from CO2 - enriched liquid with prevention of membrane structure damage. ^ 10 cl, 5 dwg, 4 tbl, 3 ex
