Process for selective removal of H/sub 2/S from mixtures containing H/sub 2/S and CO/sub 2/ using diaminoether solutions
Patent
·
OSTI ID:5674913
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 diaminoether wherein at least one amino group is a tertiary amine whereby H/sub 2/S is selectively absorbed from the mixture.
