I-PSR sulfur recovery catalyst isetyenziswa kakhulu kwiyunithi yokubuyisa i-klaus sulfur, inkqubo yokucoca igesi yesithando somlilo, inkqubo yokucoca igesi yasezidolophini, isityalo se-ammonia esenziwe ngokwenziwa, imboni yetyuwa ye-barium strontium, kunye neyunithi yokubuyisa i-sulfur kwisityalo se-methanol. Phantsi kwesenzo se-catalyst, i-Klaus reaction yenziwa ukuvelisa i-industrial sulfur.
I-catalyst yokubuyisela i-sulfur ingasetyenziswa kuyo nayiphi na i-reactor esezantsi. Ngokweemeko zokusebenza, izinga eliphezulu lokuguqulwa kwe-H2S linokufikelela kwi-96.5%, izinga le-hydrolysis le-COS kunye ne-CS2 linokufikelela kwi-99% kunye ne-70% ngokulandelanayo, uluhlu lobushushu yi-180℃ -400℃, kwaye ukumelana okuphezulu kobushushu yi-600℃. Impendulo esisiseko ye-H2S kunye ne-SO2 ukuvelisa i-element sulfur (S) kunye ne-H2O:
2H2S+3O2=2SO2+2H2O 2H2S+ SO2=3/XSX+2H2O
Yindlela engenakuphepheka ukuba isixhobo esikhulu sokubuyisa isalfure sisebenzise inkqubo yokunciphisa iClaus + (emelwe yinkqubo ye-SCOT). Umgaqo ophambili wenkqubo yokubuyisa isalfure ye-SCOT kukusebenzisa igesi yokunciphisa (efana ne-hydrogen), ukunciphisa zonke iikhompawundi zesalfure ezingezizo ze-H2S ezifana ne-S02, i-COS, i-CSS kwigesi yomsila wesixhobo sokubuyisa isalfure ukuya kwi-H2S, emva koko zifunxe kwaye zisuse i-H2S ngesisombululo se-MDEA, kwaye ekugqibeleni zibuyisele kwisithando somlilo segesi ye-asidi yesixhobo sokubuyisa isalfure ukuze ziphinde zibuyisele isalfure. Igesi yokukhupha umoya evela phezulu kwinqaba yokufunxa iqulethe i-trace sulfide kuphela, ekhutshwa emoyeni nge-incinerator kubushushu obuphezulu.
