MEMBRANE SEPARATION OF GASES Russian patent published in 2010 - IPC B01D53/14 B01D19/00 B01D61/00

Abstract RU 2390372 C2

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 CO₂is 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.
