Process for the removal of acid gases from gaseous streams

Patent ·
OSTI ID:6860678
;

Hydrogen sulfide, carbon dioxide, and carbonyl sulfide are removed from a gas stream in a staged procedure by: absorption of the CO/sub 2/ and COS; conversion of the hydrogen sulfide to produce sulfur in an absorbent mixture; hydrolysis of the carbonyl sulfide to produce a gas stream of hydrogen sulfide and carbon dioxide; and removal of the hydrogen sulfide from the gas stream.
