Abstract (en)
[origin: WO2017055192A2] An absorbent for the selective removal of hydrogen sulfide from a fluid stream containing carbon dioxide and hydrogen sulfide contains: a) an amine compound of formula (I), where X, R1 to R7, x, y and z are defined as per the description; and b) a non-aqueous solvent; wherein the absorbent contains less than 20 wt. % water. Also disclosed is a method for the selective removal of hydrogen sulfide from a fluid stream containing carbon dioxide and hydrogen sulfide, wherein the fluid stream is brought into contact with the absorbent. The absorbent is characterised by high loadability, high cyclical capacity, good regeneration characteristics and low viscosity.
