PSR sulfur dawo da mai kara kuzari ana amfani da shi ne musamman don klaus sulfur dawo da naúrar, tsarin tsarkakewar iskar gas, tsarin tsarkakewar iskar gas, shukar ammonia na roba, masana'antar gishirin barium strontium, da sashin dawo da sulfur a cikin shuka methanol. A karkashin aikin mai kara kuzari, ana gudanar da aikin Klaus don samar da sulfur na masana'antu.
Za a iya amfani da mai kara kuzari na dawo da sulfur a kowane ƙananan reactor. Dangane da yanayin aiki, matsakaicin yawan juzu'i na H2S na iya isa 96.5%, ƙimar hydrolysis na COS da CS2 na iya isa 99% da 70% bi da bi, kewayon zafin jiki shine 180 ℃ -400 ℃, kuma matsakaicin matsakaicin zafin jiki shine 600 ℃. Babban halayen H2S tare da SO2 don samar da sinadarin sulfur (S) da H2O:
2H2S+3O2=2SO2+2H2O 2H2S+ SO2=3/XSX+2H2O
Halin da babu makawa ga babban na'urar dawo da sulfur don amfani da tsarin Claus + rage-sha (wanda tsarin SCOT ke wakilta). Babban ka'ida na SCOT sulfur tsarin dawo da shi ne don amfani da rage gas (kamar hydrogen), rage duk wadanda ba H2S sulfur mahadi kamar S02, COS, CSS a cikin wutsiya gas na sulfur dawo da na'urar zuwa H2S, sa'an nan sha da desorb H2S ta hanyar MDEA bayani, kuma a karshe koma ga acid gas konewa tanderun na'urar sake dawo da sulfur dawo da na'urar.
