Claus process
Desulfurization industrial method
The Claus process is an industrial method for recovering elemental sulfur from hydrogen sulfide gas, a toxic byproduct of petroleum refining and natural gas processing.
The process involves partially burning hydrogen sulfide to produce sulfur dioxide, then reacting these gases over a catalyst to yield pure sulfur.
Named after German chemist Carl Friedrich Claus, who patented it in 1883, the process remains the most common method for large-scale sulfur production worldwide.
The refinery's Claus process unit converts waste gases into marketable sulfur.
