Abstract:
1. A process for the production of sulfur from sulfur compounds containing acid gases streams, the process comprising the following 4 steps: A—step 1) The process comprises a thermal stage(s) (reaction furnace stages) of the Claus Unit with air, enriched air or oxygen enrichment operation; B—step 2) The process comprises at least one catalytic stages containing oxygen scavenger catalyst to capture the excess oxygen from the first step, plus at least one Claus catalysts to perform the Claus reaction; C—step 3) The process comprises at least one catalytic stage containing the reduction catalyst for conversion of SO2 to sulfur and; D—step 4) The process comprises at least one catalytic stage containing the oxidation catalyst for conversion of H2S to sulfur by mixing air, enriched air or oxygen to the process gas entering the reactor.
