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.

SULFUR RECOVERY UNIT - Zeeco, Inc.

Claus Sulphur Recovery Options

the overall sulphur recoveries that can be expected when the Superclaus catalyst is used in the final bed of a Claus plant. To achieve 99 percent sulphur recovery, the tail gas from the second Claus bed is fed directly to the reactor bed containing the direct oxidation catalyst.

LARGE PLANT SULFUR RECOVERY PROCESSES STRESS …

When the acid gas feed to a Claus sulfur recovery unit SRU contains 35-45 mol % H2S or greater, the once-through Claus process is normally used.

The Process — Sulfur Recovery Engineering Inc.

THE SULFUR RECOVERY UNIT (SRU) The Sulfur Recovery Unit (SRU) is based on the modified Claus Process, which is a two-step reaction scheme overall. A portion of the total H2S is burned in the Reaction Furnace to form SO2. Then, the H2S and SO2 react, at an optimal 2:1 ratio, to form elemental Sulfur (Sx) across the Claus Reactors.
