FIELD: chemistry.SUBSTANCE: invention can be used for the absorption of carbon dioxide from a gas mixture which contains it, first of all from gaseous combustion products, from effluent gases of biological processes, calcination processes, incineration processes, etc. The method of COabsorption from a gaseous mixture by its introduction in contact with an absorbent, which contains water, sulpholane and at least one amine of formula, where Rand Rindependently on each other represent oxygen or alkyl residue. A device for COseparation from the gaseous mixture has an absorber, a desorber and a circuit of circulation of the absorbent claimed in the invention.EFFECT: invention makes it possible to carry out desorption at a higher temperature and/or decreased pressure without loss of solvents, increase a degree of carbon dioxide desorption, as well as reduce the quantity of applied corrosion inhibitors.13 cl, 3 tbl, 3 ex |
