Klaus sulfure kuchira chothandizira

PSR sulfur recovery catalyst imagwiritsidwa ntchito makamaka pa klaus sulfure recovery unit, ng'anjo yoyeretsera mpweya wa ng'anjo, makina oyeretsera gasi m'tauni, chomera chopangidwa ndi ammonia, mafakitale amchere a barium strontium, ndi gawo lobwezeretsa sulfure mufakitale ya methanol.Pansi pa chothandizira, Klaus anachita ikuchitika kupanga mafakitale sulfure.
The sulfure kuchira chothandizira angagwiritsidwe ntchito iliyonse m'munsi riyakitala.Malinga ndi zikhalidwe ntchito, pazipita kutembenuka mlingo wa H2S akhoza kufika 96.5%, ndi hydrolysis mlingo wa COS ndi CS2 kufika 99% ndi 70% motero, kutentha osiyanasiyana 180 ℃ -400 ℃, ndi pazipita kutentha kukana ndi 600 ℃.Zomwe zimachitikira H2S ndi SO2 kupanga zinthu za sulfure (S) ndi H2O:
2H2S+3O2=2SO2+2H2O 2H2S+ SO2=3/XSX+2H2O
Ndizosapeŵeka kuti chipangizo chachikulu chobwezeretsa sulfure chigwiritse ntchito njira yochepetsera ya Claus + kuchepetsa (yoyimiridwa ndi ndondomeko ya SCOT).Mfundo yaikulu ya SCOT sulfure kuchira ndondomeko ndi ntchito kuchepetsa mpweya (monga haidrojeni), kuchepetsa onse sanali H2S sulfure mankhwala monga S02, COS, CSS mu mchira mpweya wa sulfure kuchira chipangizo kuti H2S, ndiye kuyamwa ndi desorb H2S. kudzera mu njira ya MDEA, ndipo potsirizira pake kubwerera ku ng'anjo yoyaka mpweya wa asidi ya chipangizo cha sulfure kuti apezenso sulfure.Mpweya wotuluka pamwamba pa nsanjayo umangokhala ndi trace sulfide, yomwe imatulutsidwa mumlengalenga kudzera mu chotenthetsera kutentha kwambiri.
