Klaus sulfur recovery catalyst

I-PSR sulfur recovery catalyst isetyenziswa ikakhulu kwi-klaus sulfur recovery unit, i-furnace gas yokucoca inkqubo, inkqubo yokucoca igesi yasezidolophini, iplanti yokwenziwa kwe-ammonia, ishishini letyuwa ye-barium strontium, kunye neyunithi yokubuyisela isulfure kwiplanti ye-methanol. Ngaphantsi kwesenzo se-catalyst, i-Klaus reaction iqhutyelwa ukuvelisa isulfure ye-industrial.
I-catalyst yokubuyisela isulfure ingasetyenziselwa kuyo nayiphi na i-reactor ephantsi. Ngokweemeko zokusebenza, izinga eliphezulu lokuguqulwa kwe-H2S linokufikelela kwi-96.5%, izinga le-hydrolysis ye-COS kunye ne-CS2 inokufikelela kwi-99% kunye ne-70% ngokulandelanayo, iqondo lobushushu liyi-180 ℃ -400 ℃, kunye nokumelana nokushisa okuphezulu ngu-600. ℃. Ukusabela okusisiseko kwe-H2S nge-SO2 ukuvelisa i-element sulfur (S) kunye ne-H2O:
2H2S+3O2=2SO2+2H2O 2H2S+ SO2=3/XSX+2H2O
Kuyinkqubo engenakuphepheka yesixhobo esikhulu sokubuyisela isulfure ukusebenzisa inkqubo yeClaus + yokunciphisa i-absorption (emelwe yinkqubo ye-SCOT). Umgaqo oyintloko we-SCOT inkqubo yokubuyisela isulfure kukusebenzisa igesi yokunciphisa (efana ne-hydrogen), ukunciphisa zonke iikhompawundi zesulfure ezingekho ze-H2S ezifana ne-S02, i-COS, i-CSS kwigesi yomsila wesixhobo sokubuyisela isulfure kwi-H2S, emva koko ifunxe kwaye idibanise i-H2S. ngokusebenzisa isisombululo se-MDEA, kwaye ekugqibeleni ubuyele kwiziko lokutshisa igesi ye-asidi yesixhobo sokubuyisela isulfure ukubuyisela kwakhona isulfure. Irhasi ephumayo evela phezulu kwinqaba yokufunxa iqulethe kuphela i-sulfide yokulandelela, ekhutshelwa emoyeni nge-incinerator kwiqondo lokushisa eliphezulu.
