Sulfur recovery - EUROCLAUS® process

Applications: The EUROCLAUS® process recovers elemental sulphur from H2S-containing gases originating from gas treating and sour water stripper plants. The EUROCLAUS® process is an improvement of the SUPERCLAUS® process. Yields from 99.3 up to 99.5% overall sulphur recovery, without any further tail gas clean-up, are possible.

Description: The EUROCLAUS® process consists of a thermal stage followed by three or four catalytic reaction stages, with sulphur removed between stages by condensers. The final Claus reactor is filled with a layer of hydrogenation catalyst, followed by a reactor filled with selective oxidation catalyst. In the thermal stage, the acid gas is burned with a sub-stoichiometric amount of controlled combustion air; the tail gas leaving the last Claus reaction typically contains 0.8-1.0 vol.% of H2S and 100-200 ppmv SO2. This low SO2 content is obtained with a hydrogenation catalyst that converts SO2 to H2S in the bottom of the last Claus reactor. The selective oxidation catalyst in the final reactor oxidizes the H2S to sulphur at an efficiency of more than 85%. Total sulphur recovery efficiency up to 99.3% can be obtained with three reactor stages, and up to 99.5% can be achieved with four stages.
