AP-42, CH 8.13: Sulfur Recovery - US EPA

The Wellman-Lord process uses a wet generative process to reduce stack gas sulfur dioxide concentration to less than 250 ppmv and can achieve approximately 99.9 percent sulfur recovery. Claus plant tailgas is incinerated and all sulfur species are oxidized to2

Corrosion Mitigation And Monitoring In Sulfur Recovery …

The sulfur compounds are converted to elemental sulfur, and then the sulfur is condensed to liquid sulfur. The feed contains mainly hydrogen sulfides coming from amine and sour water units. Corrosion is a major concern in SRUs due to the presence of a high percentage of hydrogen sulfide, as well as high temperatures in most of the unit''s equipment.
