FIELD: technological processes.

SUBSTANCE: invention relates to a method of drying wet gas mixture, as well as an absorbent used in this method. Method of drying wet gas mixture G₁, which contains CO₂ and which is brought into contact with liquid absorbent A₁, which contains a mixture of triethylene glycol and at least one salt S selected from Q⁺A⁻, thereby producing a gas mixture G₂ reduced in comparison with a wet mixed gas G₁ and the moisture absorbent liquid A₂ with increased compared with the liquid absorbent A₁ moisture content, wherein Q⁺ is selected from a group consisting of 1,3-dimethylimidazolium-cation, 1,3-diethylimidazolium-cation, 1-ethyl-3-methylimidazolium-cation, and A⁻ is an anion selected from a group consisting of acetate, propionate, and wherein in liquid absorbent A₁ ratio between weight of triethylene glycol and total weight of all salts of S ranges from 1:9 to 9:1.

EFFECT: disclosed is a method of drying moist gas mixtures.
