Sulfur Recovery

Atmospheric emission regulations have been tightened to specifications of less than 150 mg of SO₂/Nm³, while gas fields are being developed with increasingly high levels of H₂S. The H₂S present in acid gas streams can be valorized by oxidation to elemental sulfur through Sulfur Recovery Unit. In turn, elemental Sulfur is used in the fertilizer and rubber industries, and for the extraction of some metals (copper, nickel, uranium), mainly via its intermediate conversion into Sulfuric Acid (H₂SO₄).
