Process for the selective removal of hydrogen sulfide from gaseous mixtures with strongly basic tertiary amino compounds

Patent ·
OSTI ID:5409272
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 strongly basic tertiary amino compound having a pK /SUB a/ at 20/sup 0/ C. greater than 8.6 and a boiling point at 760 mm greater than 180/sup 0/ C. whereby H/sub 2/S is selectively absorbed from the mixture.
