Abstract

In a process for removal of acid gases from a fluid stream the fluid stream is contacted with an absorbent to obtain a treated fluid stream and a laden absorbent. The absorbent comprises a diluent and a compound of the general formula (I) wherein R1 is C1-C3-alkyl; R2 is C1-C3-alkyl; R3 is selected from hydrogen and C1-C3-alkyl; and R4 is selected from hydrogen and C1-C3-alkyl.
