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 Rand Rare independently C-C-alkyl; Ris selected from hydrogen and C-C-alkyl, R, Rand Rare independently selected from hydrogen and C-C-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.
