    Sulfur recovery refers to the conversion of hydrogen sulfide (H2S) to elemental sulfur. Hydrogen sulfide is a by-product of processing natural gas and refining high-sulfur crude oils. There are many sulfur recovery technologies available for different applications, however the most common conversion method used is the Claus process. Approximately 90 to 95 percent of recovered sulfur is produced by the Claus process.
