FIELD: oil-and-gas industry.
SUBSTANCE: invention relates to extraction of acid components from gas flows, say, associated gases from wells or flue/exhaust gases with the help of membranes containing macromolecular self-organising polymer. Said gas flow (gas mix) is brought in contact with polymer (membrane). This polymer represents a macromolecular self-organising polymer material. Self-organising polymer (material) is selected from the group consisting of copolymer of ether and amide, copolymer of ester and amide, copolymer of ether and urethane, copolymer of ester and carbamide, copolymer of ether and carbamide, or mix thereof. Molecular self-organising polymer contains reiterating self-organising links of structural formulae (I)-(IV).
EFFECT: higher efficiency.
