PSR sulfur rov qab catalyst yog tsuas yog siv rau klaus sulfur rov qab tsev, lub cub tawg roj purification system, nroog gas purification system, hluavtaws ammonia cog, barium strontium ntsev kev lag luam, thiab leej faj rov qab tsev nyob rau hauv methanol cog. Nyob rau hauv qhov kev txiav txim ntawm catalyst, Klaus cov tshuaj tiv thaiv yog ua los tsim muaj sulfur.
Cov sulfur rov qab catalyst tuaj yeem siv rau hauv txhua lub reactor qis. Raws li kev ua haujlwm, qhov siab tshaj plaws hloov pauv ntawm H2S tuaj yeem ncav cuag 96.5%, tus nqi hydrolysis ntawm COS thiab CS2 tuaj yeem ncav cuag 99% thiab 70% raws li, qhov kub thiab txias yog 180 ℃ -400 ℃, thiab qhov kub siab tshaj plaws yog 600 ℃. Cov tshuaj tiv thaiv yooj yim ntawm H2S nrog SO2 los tsim cov khoom sulfur (S) thiab H2O:
2H2S + 3O2 = 2SO2 + 2H2O 2H2S + SO2 = 3 / XSX + 2H2O
Nws yog ib qho inevitable qauv rau ib tug loj sulfur rov qab ntaus ntawv siv cov Claus + txo-absorption txheej txheem (sawv cev los ntawm cov txheej txheem SCOT). Lub hauv paus ntsiab lus tseem ceeb ntawm SCOT cov txheej txheem sulfur yog siv los txo cov roj (xws li hydrogen), txo tag nrho cov tsis-H2S sulfur tebchaw xws li S02, COS, CSS nyob rau hauv tus Tsov tus tw roj ntawm cov sulfur rov qab ntaus ntawv mus rau H2S, ces nqus thiab desorb H2S los ntawm MDEA tov, thiab thaum kawg rov qab mus rau lub acid gas combustion cub rau cov sulfur rov qab ntaus ntawv. Cov pa tso pa tawm los ntawm sab saum toj ntawm lub nqus ntauwd tsuas muaj cov kab hluav taws xob sulfide, uas tau tawm mus rau hauv qhov chaw los ntawm qhov cub incinerator ntawm qhov kub siab.
