Scrubbing and oxidation of hydrogen sulfide with removal of dissolved oxygen from scrubbing solution before reuse

Patent ·
OSTI ID:6434073

In a continuous process for the removal of H/sub 2/S from a gaseous mixture involving: simultaneous absorption and oxidation of H/sub 2/S to form elemental sulfur; regeneration of the oxidizing agent, e.g., vanadate, by treating the used scrubbing liquid with air; and recycling the regenerated scrubbing liquid to the scrubbing step, to avoid the formation of sulfates and thiosulfates, the dissolved oxygen is substantially prevented from appearing in the scrubbing solution before reuse.
