    • The invention can be used to purify gas flows from impurities in a wide range of concentrations, as well as to separate gas mixtures into individual components in oil, gas, chemical and other industries. A method of absorption gas sweetening from undesirable impurities has been proposed, comprising countercurrent contact of the gas to be purified and regenerated absorbent in the mass transfer column with resulting purified gas and saturated absorbent, and a column for its implementation, packed contact device, which is separated in height into independent mass transfer sections with countercurrent or crosscurrent movement of the purified gas and regenerated absorbent, at that the flow of purified gas is sequentially passed upwards through all independent mass transfer sections of the mass transfer column, regenerated absorbent flow is introduced into the upper part of each independent mass transfer section, and saturated absorbent flow is withdrawn from the lower part of each independent mass transfer section.

    • The invention relates to a method for removing hydrogen sulphide and carbon dioxide from a stream of fluid, the method comprising: a) an absorption step, in which the stream of fluid is brought into contact with an absorption agent comprising an aqueous solution (i) of an amine of general formula (I), where R1, R2 and R3 are selected independently of one another from among C1-4 alkyl and C1-4 hydroxyalkyl; R4 in each case is independently selected from among hydrogen, C1-4 alkyl and C1-4 hydroxyalkyl; R5 in each case is selected from among hydrogen, C1-4 alkyl and C1-4 hydroxyalkyl; X represents OH or NH(CR1 R2R3); m represents 2, 3, 4 or 5; n represents 2, 3, 4 or 5; and o represents 0 or 1; and optionally (ii) at least one tertiary amine, the molar ratio of (i) to (ii) is greater than 0.05; wherein at least 90% of the hydrogen sulphide is removed from the stream of fluid, the selectivity for hydrogen sulphide in relation to carbon dioxide is no greater than 8 and a CO2- and H2S-loaded absorbent agent is thus obtained; b) a regeneration step, in which at least one sub-stream of the CO2- and H2S-loaded absorption agent is regenerated and a regenerated absorption agent is thus obtained; and c) a recirculation step, in which at least one sub-stream of the regenerated absorption agent is recirculated to the absorption step a). The method permits a high degree of separation of the hydrogen sulphide with a simultaneously high coabsorption of carbon dioxide.
