Process for selective removal of H/sub 2/S from mixtures containing H/sub 2/S and CO/sub 2/ with heterocyclic tertiary aminoalkanols

Patent ·
OSTI ID:5913641
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.
