I-Klaus sulfur recovery catalyst

I-PSR sulfur recovery catalyst isetshenziselwa ikakhulukazi iyunithi yokutakula isulfure ye-klaus, isistimu yokuhlanza igesi yesithando somlilo, isistimu yokuhlanza igesi yasemadolobheni, imboni yokwenziwa ye-ammonia, imboni kasawoti ye-barium strontium, kanye neyunithi yokubuyisela isulfure embonini ye-methanol. Ngaphansi kwesenzo se-catalyst, ukusabela kukaKlaus kwenziwa ukukhiqiza isulfure yezimboni.
I-catalyst yokubuyisela isulfure ingasetshenziswa kunoma iyiphi i-reactor ephansi. Ngokwezimo zokusebenza, izinga eliphezulu lokuguqulwa kwe-H2S lingafinyelela ku-96.5%, izinga le-hydrolysis le-COS ne-CS2 lingafinyelela ku-99% no-70% ngokulandelana, izinga lokushisa liyi-180 ℃ -400 ℃, futhi izinga lokushisa eliphakeme lokumelana ngu-600 ℃. Ukusabela okuyisisekelo kwe-H2S nge-SO2 ukukhiqiza izakhi zesulfure (S) ne-H2O:
2H2S+3O2=2SO2+2H2O 2H2S+ SO2=3/XSX+2H2O
Kuwumkhuba ongenakugwemeka womshini omkhulu wokubuyisela isibabule ukusebenzisa inqubo ye-Claus + yokunciphisa ukumuncwa (emelwe inqubo ye-SCOT). Umgomo oyinhloko wenqubo yokutakula isulfure ye-SCOT ukusebenzisa igesi yokunciphisa (njenge-hydrogen), ukunciphisa zonke izinhlanganisela zesulfure ezingezona i-H2S ezifana ne-S02, i-COS, i-CSS kugesi lomsila wedivayisi yokutakula isulfure kuya ku-H2S, bese udonsa futhi ukhiphe i-H2S ngesisombululo se-MDEA, futhi ekugcineni ubuyele ku-acid gas combusation idivayisi yokuvuselela isibabule esivuthayo. Igesi yokukhipha ephumayo evela phezulu kombhoshongo wokumuncwa iqukethe i-trace sulfide, ekhishelwa emkhathini ngomshini wokushisisa ukushisa okuphezulu.
