The Sulfur Recovery Unit or Claus unit converts undesirable, toxic H2S gas into beneficial elemental sulfur. This process utilizes different types of Claus catalyst to facilitate the conversion.


Purification catalyst removes contaminants from liquid and gas processes using catalytic, regenerative, or sacrificial means. The catalyst is typically a mixed metal oxide formulated to remove specific contaminants. The catalyst can be in tabular or extrudate, or sphere shape.
