Abstract: A process for selectively separating H2S from a gas mixture which also comprises CO2 is disclosed. A stream of the gas mixture is contacted with an absorbent solution comprising one or more amines, alkanolamines, hindered alkanolamines, capped alkanolamines, or mixtures thereof. The H2S/CO2 selectivity of the absorbent solution is preferably greater than about 4.0 for an acid gas loading [mol(CO2+H2S)/mol(amine)] between about 0.2 and about 0.6, and is achieved by reducing pH of the absorbent solution.

Abstract: An absorbent for the selective removal of hydrogen sulfide over carbon dioxide from a fluid stream, wherein the absorbent contains an aqueous solution, comprising an amine of formula (I) and/or an amine of formula (II) wherein U—V—W is CH—O—CHR5, N—CO—CHR5 or N—CO—NR5; U′—V′—W is C—O—CR5; R1 is independently C1-C5-alkyl; R2 is selected from hydrogen and C1-C5-alkyl; R3 is independently selected from hydrogen and C1-C5-alkyl; R4 is independently selected from hydrogen and C1-C5-alkyl; R5 is selected from hydrogen, C1-C5-alkyl, (C1-C5-alkoxy)-C1-C5-alkyl, and hydroxy-C1-C5-alkyl; and x is an integer from 1 to 10. The absorbent has a reduced tendency for phase separation at temperatures falling within the usual range of regeneration temperatures for the aqueous amine mixtures and a low volatility in aqueous solvents.

Abstract: An absorbent for the selective removal of hydrogen sulfide from a fluid stream comprising carbon dioxide and hydrogen sulfide, wherein the absorbent contains an aqueous solution, comprising: a) an amine or a mixture of amines of the general formula (I) wherein R1 is C1-C5-alkyl; R2 is C1-C5-alkyl; R3 is selected from hydrogen and C1-C5-alkyl; x is an integer from 2 to 10; and b) an ether or a mixture of ethers of the general formula (II): R4—[O—CH2—CH2]y—OH; wherein R4 is C1-C5-alkyl; and y is an integer from 2 to 10; wherein R1 and R4 are identical; wherein the mass ratio of b) to a) is from 0.08 to 0.5. The absorbent is suitable for the selective removal of hydrogen sulfide from a fluid stream comprising carbon dioxide and hydrogen sulfide. The absorbent has a reduced tendency for phase separation at temperatures falling within the usual range of regeneration temperatures for the aqueous amine mixtures and is easily obtainable.

Abstract: A process for removing acid gases from a fluid stream, wherein the fluid stream is contacted with an absorbent comprising a compound of the general formula (I), wherein R1 and R2 are independently C1-C4-alkyl; R3 is selected from hydrogen and C1-C4-alkyl, R4, R5 and R6 are independently selected from hydrogen and C1-C4-alkyl; x and y are integers from 2 to 4 and z is an integer from 1 to 3, to obtain a treated fluid stream and a laden absorbent. The process allows for a high cyclic capacity while the compounds of the absorbent have a reduced tendency to foaming and low volatility.

Abstract: A process for producing a deacidified fluid stream from a fluid stream comprising methanol and at least one acid gas, comprising
a) an absorption step in which the fluid stream is contacted with an absorbent in an absorber to obtain an absorbent laden with methanol and acid gases and an least partly deacidified fluid stream;
b) a regeneration step in which at least a portion of the laden absorbent obtained from step a) is regenerated in a regenerator to obtain an at least partly regenerated absorbent and a gaseous stream comprising methanol and at least one acid gas;
c) a recycling step in which at least a substream of the regenerated absorbent from step b) is recycled into the absorption step a);
d) a condensation step in which a condensate comprising methanol is condensed out of the gaseous stream from step b);
wherein the regenerator additionally comprises a rescrubbing section, and the condensate from step d) is recycled into the regenerator partly in the upper region of the rescrubbing zone or above the rescrubbing zone.
