Abstract:
An absorbent for selective removal of hydrogen sulfide from a fluid stream comprising carbon dioxide and hydrogen sulfide comprises a) an amine compound of the formula (I) in which X, R 1  to R 7 , x, y and z are as defined in the description; and b) a nonaqueous solvent; where the absorbent comprises less than 20% by weight of water. Also described is a process for selectively removing hydrogen sulfide from a fluid stream comprising carbon dioxide and hydrogen sulfide, wherein the fluid stream is contacted with the absorbent. The absorbent features high load capacity, high cyclic capacity, good regeneration capacity and low viscosity.

Claim (Index 10):
The absorbent according to  claim 1 , wherein the absorbent further comprises a tertiary amine or highly sterically hindered amine other than the compounds of the formula (I) and (II), wherein high steric hindrance means a tertiary carbon atom directly adjacent to a primary or secondary nitrogen atom.
