    Abstract: 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.

    Abstract: A process for removal of acid gases from fluid stream, wherein the fluid stream is brought into contact with an absorbent to obtain a treated fluid stream and a laden absorbent, the absorbent comprising a diluent and a compound of the general formula (I) wherein R1 is selected from C1-C8-alkyl and C2-C8-hydroxyalkyl; R2 is selected from hydrogen and C1-C8-alkyl; R3 is selected from hydrogen and C1-C8-alkyl; R4 is selected from hydrogen and C1-C8-alkyl; R5 is C1-C8-alkyl; with the proviso that at least one of the following conditions (i) and (ii) is met: (i) R5 is C3-C8-alkyl bound to the nitrogen atom via a secondary or tertiary carbon atom; (ii) when R4 is hydrogen, R3 is C1-C8-alkyl; or when R4 is C1-C8-alkyl, at least one of R2 and R3 is C1-C8-alkyl; and n is an integer from 0 to 6. Further provided is an absorbent for the absorption of acid gases from a fluid stream, comprising a diluent and a compound of the general formula (I) as defined above, as well as the use of a compound of the general formula (I) as defined above for removal of acid gases from a fluid stream. The absorbents are useful for the selective removal of hydrogen sulfide from fluid streams and have high acid gas loading capacity, high stability, and low volatility.
