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.

Refractory Ferrules Selection Guide | Engineering360

Refractory ferrules are designed to protect boiler tube inlet areas and metal tube sheets in sulfur recovery units (SRUs) used in oil refinery operations. Boiler tube inserts are also used in methane reformers and waste heat boilers (WHB). Refractory ferrules are made of materials called refractories that have high melting points.
