<p>Hydrogen sulfide is removed from coke oven gas by a regenerative scrubber-stripper system, and the concentrated sour gas is fed to a Claus unit for catalytic conversion to elemental sulfur using atmospheric oxygen. The Claus unit is operated with a single furnace at a temperature of less than 250degreesC, and the tail gas is recycled to the raw gas scrubber.</p> |
