Abstract
A process for selectively separating HS from a gas mixture which also comprises COis disclosed. A stream of the gas mixture is contacted with an absorbent solution comprising one or more amines, alkanolamines, hindered alkanolamines, capped alkanolamines, or mixtures thereof. The HS/COselectivity of the absorbent solution is preferably greater than about 4.0 for an acid gas loading [mol(CO+HS)/mol(amine)] between about 0.2 and about 0.6, and is achieved by reducing pH of the absorbent solution.
