20.6.3 Sulfur Recovery. 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
