METHOD OF INCREASING EFFICIENCY OF REMOVING CARBON DIOXIDE AND HYDROGEN SULPHIDE FROM METHANE-CONTAINING GAS MIXTURES Russian patent published in 2024 - IPC B01D53/00 B01D53/14 B01D53/44 B01D53/52 B01D53/62

Abstract RU 2823675 C2

FIELD: chemistry.

SUBSTANCE: invention relates to methods for selective removal of carbon dioxide and hydrogen sulphide from methane-containing gas mixtures by absorption and can be used in gas, oil and other chemical industries. Described is a method of increasing efficiency of removing acid gases from natural gas by using a combined absorption system containing an aqueous solution of methyldiethanolamine and an ionic compound of bis-(2-hydroxyethyl)-dimethylammonium taurate.

EFFECT: increased sorption capacity of aqueous solutions of methyldiethanolamine with respect to CO₂ and H₂S.
