Chothandizira kuchira sulfure cha PSR chimagwiritsidwa ntchito makamaka pa chipangizo chobwezeretsa sulfure cha klaus, makina oyeretsera gasi mu uvuni, makina oyeretsera gasi mumzinda, fakitale yopanga ammonia, makampani a mchere wa barium strontium, ndi chipangizo chobwezeretsa sulfure mu fakitale ya methanol. Pogwiritsa ntchito chothandizira, Klaus reaction imachitika kuti ipange sulfure yamafakitale.
Chothandizira kubwezeretsa sulfure chingagwiritsidwe ntchito mu reactor iliyonse yotsika. Malinga ndi momwe ntchito ikuyendera, kuchuluka kwakukulu kwa kusintha kwa H2S kumatha kufika 96.5%, kuchuluka kwa hydrolysis kwa COS ndi CS2 kumatha kufika 99% ndi 70% motsatana, kutentha kwapakati ndi 180℃ -400℃, ndipo kukana kutentha kwakukulu ndi 600℃. Momwe H2S imachitira ndi SO2 popanga element sulfur (S) ndi H2O:
2H2S+3O2=2SO2+2H2O 2H2S+ SO2=3/XSX+2H2O
Ndi chizolowezi chosapeŵeka kuti chipangizo chachikulu chobwezeretsa sulfure chigwiritse ntchito njira ya Claus + reduction-absorption (yomwe ikuimiridwa ndi njira ya SCOT). Mfundo yaikulu ya njira yobwezeretsa sulfure ya SCOT ndikugwiritsa ntchito mpweya wochepetsa (monga hydrogen), kuchepetsa mankhwala onse a sulfure omwe si a H2S monga S02, COS, CSS mu mpweya wammbuyo wa chipangizo chobwezeretsa sulfure kupita ku H2S, kenako kuyamwa ndi kuchotsa H2S kudzera mu yankho la MDEA, kenako ndikubwerera ku ng'anjo yoyaka ya mpweya wa asidi wa chipangizo chobwezeretsa sulfure kuti akabwezeretse sulfure. Mpweya wotuluka kuchokera pamwamba pa nsanja yoyamwa uli ndi sulfure yochepa yokha, yomwe imatulutsidwa mumlengalenga kudzera mu incinerator pa kutentha kwakukulu.
