Introduction
The Claus process (SRU) is the primary sulfur removal process in petrochemical industries. It extracts elemental sulfur from hydrogen sulfide present in natural gas and gases produced as byproducts during crude oil refining. Currently, a significant portion of the world’s sulfur demand is met through this process, making the Frasch process less common. This process was invented by Carl Friedrich Claus, a German chemist residing in England, and patented in 1883. After the Claus process, the SCOT process is employed in refineries, which handles oxidation and separation.
