摘要： The invention relates to a method for treating an H2S and CO2-containing fluid flow, wherein a) the fluid flow is treated with a first sub-flow (3.01) of a regenerated H2S-selective absorbent in a first absorber (A1) at a pressure of 10 to 150 bar, and a treated fluid flow (3.03) and an H2S-loaded absorbent (3.04) are obtained; b) the H2S-loaded absorbent is heated by means of an indirect heat exchange (3.07) with a regenerated H2S-selective absorbent (3.08); c) the heated H2S-loaded absorbent (3.09) is expanded to a pressure of 1.2 to 10 bar in a low-pressure expansion container (LPF), and a first CO2-enriched exhaust gas and a partially regenerated absorbent (3.11) are obtained; d) the partially regenerated absorbent (3.11) is regenerated in a desorption column (D), and an H2S-enriched exhaust gas (3.23) and a regenerated absorbent (3.08) are obtained; e) the H2S-enriched exhaust gas (3.23) is supplied to a Claus unit (CL), the exhaust gas of the Claus unit is supplied to a hydrogenation unit (HY), and a hydrogenated Claus final gas is obtained; f) the hydrogenated Claus final gas and the first CO2-enriched exhaust gas are treated with a second sub-flow (3.18) of the regenerated H2S-selective absorbent (3.17) in a second absorber (TGA) at a pressure of 1 to 4 bar, and a second CO2-enriched exhaust gas (3.25) and a second H2S-loaded absorbent (3.02) are obtained; and g) the second H2S-loaded absorbent is conducted into the first absorber (A1). The invention further relates to a system which is suitable for carrying out the method. The invention is characterized by a low energy requirement.

摘要： The invention relates to an absorbent for the selective removal of hydrogen sulfide from a fluid stream, containing an aqueous solution comprising a) a tertiary amine; b) an amine pH promoter, selected from the compounds mentioned in the description; wherein the molar ratio between b) and a) is in the range of 0.05 to 1.0; and c) an acid having a pK
s value of less than 6 in an amount such that the pH value of the aqueous solution is 7.9 to less than 8.8 when measured at 120 °C. Furthermore, the invention relates to a method for the removal of acid gases from a fluid stream, in which the fluid stream is brought into contact with the absorbent. The absorbent is characterized by a low regeneration energy.

摘要： 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 R

3 are selected independently of one another from among C
1-4 alkyl and C
1-4 hydroxyalkyl; R
4 in each case is independently selected from among hydrogen, C
1-4 alkyl and C
1-4 hydroxyalkyl; R
5 in each case is selected from among hydrogen, C
1-4 alkyl and C
1-4 hydroxyalkyl; X represents OH or NH(CR
1 R

3 ); 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 CO
2 - and H
2 S-loaded absorbent agent is thus obtained; b) a regeneration step, in which at least one sub-stream of the CO
2 - and H
2 S-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.
