ABSTRACT:
The gases discharged from the sulfur condenser of a Claus process reactor are contacted with an active adsorbent to remove further sulfur and the resulting exhaust gas is afterburned. A desorption gas is passed in closed cycle through the laden adsorbent and is heated, in this cycle, in heat exchange with the hot gases emerging from the afterburner. The sulfur is condensed from the desorption gas with the same cooling system used for the Claus process condensation and water vapor produced by the cooling system is condensed and by gravity is returned to the condensation stage.
