ABSTRACT:
The selective removal of H.sub.2 S gas from a normally gaseous mixture containing H.sub.2 S and CO.sub.2 is accomplished by contacting the gaseous mixture with an absorbent solution comprising a nitrogen heterocyclic tertiary aminoalkanol or aminoetheralkanol whereby H.sub.2 S is selectively absorbed from the mixture.
