I-PSR sulfur recovery catalyst isetshenziswa kakhulu kwiyunithi yokubuyisa i-klaus sulfur, uhlelo lokuhlanza igesi esithandweni, uhlelo lokuhlanza igesi emadolobheni, isitshalo se-ammonia esenziwe ngokwenziwa, imboni kasawoti we-barium strontium, kanye neyunithi yokubuyisa i-sulfur esitshalweni se-methanol. Ngaphansi kwesenzo se-catalyst, i-Klaus reaction yenziwa ukukhiqiza i-sulfur yezimboni.
I-catalyst yokubuyisa i-sulfur ingasetshenziswa kunoma iyiphi i-reactor ephansi. Ngokwezimo zokusebenza, izinga lokuguqulwa eliphezulu le-H2S lingafinyelela ku-96.5%, izinga le-hydrolysis le-COS ne-CS2 lingafinyelela ku-99% kanye no-70% ngokulandelana, ububanzi bokushisa bungu-180℃ -400℃, kanti ukumelana okuphezulu kokushisa kungu-600℃. Ukusabela okuyisisekelo kwe-H2S ne-SO2 ukukhiqiza i-element sulfur (S) kanye ne-H2O:
2H2S+3O2=2SO2+2H2O 2H2S+ SO2=3/XSX+2H2O
Kuyindlela engenakugwenywa ukuthi idivayisi enkulu yokutakula isibabule isebenzise inqubo yokumunca i-Claus + yokunciphisa (emelelwa inqubo ye-SCOT). Umgomo oyinhloko wenqubo yokutakula isibabule se-SCOT ukusebenzisa igesi yokunciphisa (njenge-hydrogen), ukunciphisa zonke izinhlanganisela zesibabule ezingezona i-H2S njenge-S02, i-COS, i-CSS kugesi yomsila wedivayisi yokutakula isibabule iye ku-H2S, bese imunca futhi isuse i-H2S ngesisombululo se-MDEA, bese ekugcineni ibuyela esithandweni sokushisa igesi ye-acid sedivayisi yokutakula isibabule ukuze ithole isibabule ngokwengeziwe. Igesi yokukhipha umoya evela phezulu kombhoshongo wokumunca iqukethe i-trace sulfide kuphela, ekhishwa emoyeni nge-incinerator ekushiseni okuphezulu.
