Sulfur Recovery in Claus Plants Linde Gas
Claus plants play a key role in refinery productivity. They process concentrated hydrogen sulfide (H 2 S) fractions converting them into sulfur dioxide (SO 2) and ultimately elemental sulfur They can also remove pollutants particularly those caused by decomposing ammonia. Today many refinery operators are challenged to manage rising H 2 S levels. On the one hand dwindling reserves mean the average S

Claus Processan overview ScienceDirect Topics
The most common sulfur recovery process is the Claus process where one-third of the H 2 S must be converted to SO 2 for proper stoichiometry. The theoretical sulfur recovery efficiency drops sharply when the stoichiometry differs from the desired 2 mol of H 2 S to 1 mol of SO 2. A proper amount of oxygen typically in the form of air must be introduced to the reaction furnace.
