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 ib qho qis reactor. 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 tseem ceeb 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 kev tsis pom zoo rau cov khoom siv hluav taws xob loj loj los siv cov txheej txheem Claus + txo kev nqus (sawv cev los ntawm cov txheej txheem SCOT). Lub hauv paus ntsiab lus tseem ceeb ntawm SCOT cov txheej txheem sulfur rov qab yog siv los txo cov pa 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 rau H2S, ces nqus thiab desorb H2S. los ntawm MDEA cov tshuaj, thiab thaum kawg rov qab mus rau lub acid gas combustion rauv ntawm cov sulfur rov qab ntaus ntawv kom rov qab sulfur ntxiv. 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.
