Claus process - Wikipedia

The Claus process is the most significant gas desulfurizing process, recovering elemental sulfur from gaseous hydrogen sulfide.First patented in 1883 by the chemist Carl Friedrich Claus, the Claus process has become the industry standard.C. F. Claus was born in Kassel in the German State of Hessen in 1827, and studied chemistry in Marburg before he emigrated to England in 1852.
