摘要：
In a continuous process for the removal of H.sub.2 S from a gaseous mixture involving: (a) simultaneous absorption and oxidation of H.sub.2 S to form elemental sulfur; (b) regeneration of the oxidizing agent, e.g., vanadate, by treating the used scrubbing liquid with air; and (c) 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.
