Ana amfani da skid na iskar gas na wutsiya don magance wutsiya na na'urar dawo da sulfur, da kuma iskar gas na ruwa sulfur pool da TEG iskar gas na bushewar na'urar dawo da sulfur.
Ƙirar ƙira da ƙarfin sarrafawa na skid sun dace da na'urar dawo da sulfur da na'urar bushewa.
Za a iya raba skid na maganin wutsiya na iskar gas zuwa rukuni huɗu

1. Ragewa da tsarin sha
Ka'idar ragewa da tsarin sha shine cewa iskar gas ɗin wutsiya ta kasance hydrogenated, abubuwan da ke ɗauke da sulfur a cikin iskar wutsiya an rage su zuwa H2S, H2S da aka ƙirƙira ana zaɓin shayar da shi ta hanyar amine, kuma a ƙarshe ana fitar da sabuntawa ko iskar gas don shigar da sashin Claus don ɗaukar martani. Tsarin hydrogenation yana da babban saka hannun jari da tsadar aiki, amma ana amfani dashi sosai a cikin ƙasashe da yankuna tare da buƙatun kare muhalli masu girma saboda yana iya samun yawan amfanin ƙasa na sulfur daidai, kamar fiye da 99.8%.

2 Tsarin sha na Oxidation
Hanyar shan Oxidation wata hanya ce da ta fara oxidizes sulfide a cikin iskar gas ɗin wutsiya zuwa SO2, sannan ya sha SO2 da bayani (ko sauran ƙarfi), sannan a ƙarshe ya dawo da shi ta hanyar sulfate, sulfide da SO2.
Akwai hanyoyi da yawa na irin wannan nau'in, galibi ana amfani da su don lalata iskar gas ko kuma kula da iskar wutsiya daga masana'anta da tsire-tsire na sulfuric acid, kuma ana amfani da hanyar Wellman Lord don maganin iskar gas na Claus.

3. Low zafin jiki Claus tsari
Fasahar Claus mai ƙarancin zafin jiki tana da halayen Claus a ƙasan raɓa na sulfur, don haka ana kiranta tsarin dawo da raɓa na sulfur. Halin Claus tsari ne mai ƙarfi na exothermic. Sabili da haka, ƙananan zafin jiki yana dacewa da sauyawar ma'auni zuwa jagorancin samar da sulfur, wanda zai iya inganta farfadowa na sulfur. Dangane da alakar da ke tsakanin amsawar Claus da naúrar, ana iya raba tsarin Claus ƙananan zafin jiki zuwa tsarin ƙananan zafin jiki mai zaman kansa da kuma haɗa ƙananan tsarin Claus.

4. Liquid lokaci kai tsaye hadawan abu da iskar shaka tsari
Tsarin hadawan abu da iskar shaka kai tsaye wani nau'in fasahar tsari ne wanda ke fitar da H2S kai tsaye zuwa sulfur na farko. Ka'idar wannan tsari shine ɗaukar H2S a cikin iskar wutsiya tare da maganin desulfurization, sannan oxidize shi don samar da sulfur na asali.
