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: 1,3-Diaminocyclohexanes of the general formula (I) are suitable for removing carbon dioxide from fluid streams where the radicals R are each, independently of one another, C1-4-alkyl; and n is an integer from 0 to 3. The amino groups of the 1,3-diaminocyclohexane are preferably arranged in trans position relative to one another in the plane of the cyclohexane ring. Absorption media for removing carbon dioxide from fluid streams comprise a) a 1,3-diaminocyclohexane of the general formula (I) and b) optionally at least one tertiary amine and/or a sterically hindered primary or secondary amine. In a process for removing carbon dioxide from fluid streams, the absorption medium is brought into contact with a fluid stream.
