Hauv kev ua tiav kev lag luam sulfur rov qab, cov txheej txheem Claus tuaj yeem paub qhov kev rov qab los ntawm feem ntau cov sulfur Cheebtsam, tab sis txwv los ntawm cov tshuaj sib npaug thiab cov tshuaj tiv thaiv, ib qho me me ntawm Hydrogen Sulfide, sulfur dioxide thiab residual Organic-sulfur Compound tseem yuav nyob twj ywm hauv cov roj av. Yog tias tsis kho kom tob, cov pa phem no yuav tsis tsuas yog ua rau cov khoom siv sulfur pov tseg, tab sis kuj ua rau cov pa hluav taws xob ntau dhau. Yog li ntawd, tiav Claus Tail Gas Treatment system tau dhau los ua ib feem tseem ceeb ntawm kev lag luam ib puag ncig kev tiv thaiv kev tsim khoom, thiab Hydrogenation Catalyst, tshwj xeeb tshaj yog cov kws tshaj lij Tail Gas Hydrogenation Catalyst, tau dhau los ua tus yuam sij rau kev ua kom huv ntawm tus Tsov tus tw thiab tag nrho cov qauv tawm ntawm SRU (Sulfur Recovery Unit). Kev koom tes nrog siab -kev ua tau zoo Sulfur Recovery Catalyst thiab lwm yam kev lag luam catalysts, nws tsim kom muaj tag nrho - txheej txheem sulfur rov qab thiab tus Tsov tus tw Gas purification system kom ua tiav cov peev txheej rov qab los thiab kev tiv thaiv ib puag ncig.
Sib txawv ntawm Claus Process Catalyst siv rau cov txheej txheem tseem ceeb hloov dua siab tshiab, lub luag haujlwm tseem ceeb ntawm Tail Gas Hydrogenation Catalyst yog kom paub txog kev txo qis thiab sib sib zog nqus hloov pauv ntawm cov seem sulfur hauv Claus tail gas. Cov roj av uas tsim los ntawm lub ntsiab chav tsev ntawm SRU (Sulfur Recovery Unit) muaj ntau yam ntawm cov tshuaj sulfur uas tsis tuaj yeem hloov pauv los ntawm Claus txheej txheem, suav nrog cov seem sulfur dioxide, tsis muaj tshuaj hydrogen sulfide, thiab ruaj khov Organic-sulfur Compound xws li COS thiab CS₂. Cov tshuaj no muaj cov qauv molecular ruaj khov thiab nyuaj rau cov pa decomposition, uas yog lub ntsiab yog vim li cas rau qhov tsis txaus tag nrho cov sulfur rov qab tus nqi ntawm cov cuab yeej thiab cov roj emissions ntau dhau. Lub siab -Kev ua tau zoo Hydrogenation Catalyst tuaj yeem ua kom muaj txiaj ntsig zoo rau cov tshuaj tiv thaiv hydrogenation txo nyob rau hauv lub Tail Gas kho reactor, hloov txhua hom sulfur- muaj cov khoom xyaw rau hauv Hydrogen Sulfide dua, thiab tom qab ntawd xa lawv rov qab mus rau lub ntsiab Claus chav tsev rau lub voj voog thib ob rov qab, daws cov teeb meem ntawm cov pa roj hauv seem.
Cov qauv tsim thiab kev ua tau zoo ntawm cov kws tshaj lij tail gas hydrogenation catalytic cov ntaub ntawv tau txais txiaj ntsig zoo rau qhov chaw ua haujlwm hnyav ntawm kev kho tus nplaig roj. Lub txaj Catalyst uas muaj Tail Gas Hydrogenation Catalyst yuav tsum ua haujlwm ruaj khov rau lub sijhawm ntev hauv siab -kub, siab - av noo thiab plua plav- muaj cov roj av nyuaj, thiab tiv thaiv qhov cuam tshuam ntawm cov kab tsis huv xws li hnyav hydrocarbons thiab sulfides. Lub upgradedHydrogenation Catalyst txais siab - lub zog inert carrier thiab multi-element composite active Cheebtsam, nrog high hydrogenation kev ua si, muaj zog tiv thaiv - toxicity thiab zoo heev thermal stability. Nws tuaj yeem tswj tau cov peev xwm txo qis hauv catalytic hauv qhov sib txawv ntawm qhov sib txawv thiab hloov pauv cov roj muaj pes tsawg leeg, xyuas kom meej hydrogenation hloov dua siab tshiab ntawm tag nrho cov seem sulfur, thiab nteg lub hauv paus rau kev rov qab los ntawm Elemental Sulfur.
Kev sib koom ua haujlwm ntawm Sulfur Recovery Catalyst nyob rau hauv cov txheej txheem tseem ceeb thiab Hydrogenation Catalyst nyob rau hauv tus Tsov tus tw gas seem tsim ib tug kaw - voj puv - voj voog kev kho mob hom ntawm SRU (Sulfur Recovery Unit). Nyob rau hauv lub ntsiab cov tshuaj tiv thaiv theem, Claus txheej txheem Catalyst zoo converts feem ntau Hydrogen Sulfide rau hauv cov khoom sulfur elemental; Nyob rau hauv lub Tail Gas purification theem, Tail Gas Hydrogenation Catalyst ua qhov sib sib zog nqus hydrogenation txo nyob rau hauv residual sulfur tebchaw kom paub qhov thib ob recycling. Qhov ob -theem catalytic linkage hom no ua rau tag nrho cov kev txwv hloov pauv ntawm ib txoj kev Claus, txhim kho tag nrho cov khoom siv sulfur rov qab los ntawm cov cuab yeej, thiab ua rau cov purity ntawm recycled Elemental Sulfur siab dua thiab kev siv cov nqi ntau dua.
Hais txog cov txiaj ntsig kev tiv thaiv ib puag ncig, qhov zoo sib xws ntawm ob hom kev ua haujlwm siab -kev ua haujlwm catalysts paub txog ultra- qis qis ntawm Claus Tail Gas Treatment. Tom qab sib sib zog nqus hydrogenation thiab cyclic rov qab kho, cov ntsiab lus ntawm leej faj nyob rau hauv lub kawg tso tawm flue roj yog deb tshaj li nruj tshaj thoob ntiaj teb ib puag ncig tiv thaiv qauv, pab tshuaj lag luam daws cov teeb meem ntawm flue gas emission ua raws. Nyob rau tib lub sijhawm, kev siv hluav taws xob zoo rov ua kom txo tau cov khoom pov tseg ntawm cov khoom siv sulfur, paub txog kev rov qab siv cov khoom siv khib nyiab, ua raws li lub ntiaj teb ntsuab tshuaj lom neeg txoj kev loj hlob lub tswv yim ntawm kev txuag hluav taws xob, txo qis emissions thiab cov peev txheej rov ua dua tshiab, thiab txo cov kev tiv thaiv ib puag ncig thiab kev siv peev txheej ntawm cov lag luam.
Daim ntawv thov kev lag luam tawm tswv yim qhia tau hais tias kev sib koom ua ke catalytic tswv yim tsim los ntawm Sulfur Recovery Catalyst thiab Tail Gas Hydrogenation Catalyst tau ua tiav hauv ntau qhov loj -scale petrochemical thiab natural gas purification project. Piv nrog rau cov txheej txheem kev kho ib zaug ib zaug, tag nrho cov tshuaj sulfur rov ua haujlwm ntawm cov cuab yeej tau zoo dua qub, qhov ua tsis tiav ntawm Catalyst txaj yog txo, thiab kev pabcuam kev pabcuam ntawm cov khoom siv catalytic tau ntev. Qhov ruaj khov thiab muaj txiaj ntsig catalytic kev ua tau zoo txo qhov zaus ntawm kev hloov pauv catalyst thiab cov khoom siv tu, thiab txuag tau lub sijhawm ntev - cov nqi ua haujlwm ntawm kev lag luam SRU (Sulfur Recovery Unit).
Cov neeg sab hauv kev lag luam tau hais tias tag nrho - lub voj voog qhov tseeb catalysis thiab tag nrho - cov peev txheej rov qab los yuav yog qhov kev txhim kho tsis pom kev ntawm kev lag luam sulfur rov qab thev naus laus zis yav tom ntej. Cov txiaj ntsig ntxiv ntawm Claus Process Catalyst thiab Hydrogenation Catalyst yuav txuas ntxiv txhawb kev txhim kho Claus Tail Gas Treatment thev naus laus zis. Kev ua kom zoo tsis tu ncua ntawm kev ua haujlwm siab -kev ua tau zoo, tiv thaiv- tshuaj lom thiab ntev- lub neej catalysts yuav ntxiv dag zog rau kev siv cov khoom siv hluav taws xob ntawm kev lag luam sulfur- muaj cov roj khib nyiab, pab kev lag luam tshuaj lom neeg thoob ntiaj teb ua tiav siab dua - theem ntsuab thiab qis - carbon txoj kev loj hlob, thiab tsim kom muaj kev tiv thaiv ib puag ncig zoo dua rau kev lag luam.
