Siv tau Deoxidizer

Khoom npe: Efficient deoxidizer (BASF Puristar R3-11G)

Kev ua kom zoo deoxidizer yog qhov ua tau zoo - deoxidizer nrog tooj liab oxide ua lub luag haujlwm tseem ceeb thiab manganese oxide ua tus neeg sawv cev pabcuam.

Hauv cov khoom siv, hluav taws xob, tshuaj lom neeg kev lag luam, thiab lwm yam, muaj cov kab mob oxygen feem ntau muaj teeb meem. Oxygen tuaj yeem ua rau qee cov polymerization catalysts. Lub xub ntiag ntawm cov pa tuaj yeem ua rau qee cov roj hluav taws kub thiab tawg, uas tuaj yeem ua rau muaj teeb meem hauv kev tsim khoom.

Kev sib kis ua rau muaj kev nyab xeeb zoo, thiab lwm yam, nrog rau kev loj hlob sai ntawm kev tshawb fawb, thev naus laus zis thiab kev tsim khoom lag luam, uas tau muab tso rau hauv kev xav tau ntau dua rau cov khoom zoo. Piv txwv li, nyob rau hauv cov pa purification system ntawm cov ntaub ntawv tshiab thiab electronics industrial ntau lawm kab, O₂raug tshem tawm los ntawm kev lag luam electrolytic hydrogen thiab huab cua sib cais nitrogen, thiab lub tshuab hluav taws xob roj yog deoxidized los tsim "enriched gas", uas yog siv los ua cov roj tiv thaiv rau kev tsim thiab ua cov hlau tshwj xeeb. Deoxygenation ntawm cov pa roj siv rau kev kho cua sov thiab siab - cov pa purity xav tau rau kev tshawb fawb tshawb fawb tag nrho muab cov kev xav tau siab ntawm cov pa oxygen hauv cov pa roj nyoos.

Cov deoxidizer zoo tuaj yeem tshem tawm cov pa oxygen los ntawm cov pa roj carbon monoxide thiab kua hydrocarbons ntawm qhov kub thiab txias. Nws yog dav siv hauv ethylene, Sib sib zog nqus tshem tawm cov pa oxygen hauv propylene, nitrogen, hydrogen, CO₂thiab tshem tawm methane. Tom qab deoxidation, cov ntsiab lus oxygen hauv cov roj nyoos tuaj yeem raug txo kom tsawg dua 0.1ppm.

Kev ua tau zoo deoxidizer muaj qee daim ntawv thov:

1) Recycling thiab Siv Cov Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob

Cov pa tso pa tawm los ntawm kev tsim khoom lag luam muaj ntau cov khoom tseem ceeb, tab sis vim muaj O₂.

Tam sim no, nws yooj yim tawg, ua rau muaj teeb meem kev siv dua tshiab. Piv txwv li, nyob rau hauv cov txheej txheem ntawm chlorohydrin ntau lawm ntawm propylene oxide, cov pa pa muaj li 50% propylene thiab propane, thiab lwm yam., nrog rau cov nqi rov qab ntau heev. Deoxidizer tuaj yeem tshem tawm cov pa seem hauv propylene thiab propane zoo.

2) High purity gas thiab tiv thaiv roj npaj

High-purity nitrogen yuav tsum muaj cov pa oxygen hauv cov pa kom tsawg dua 5 ppm, thiab kev tsim cov siab -purity nitrogen los ntawm cov nitrogen ntau yuav tsum tau deoxygenation.

Raws li kev ua ntawm deoxidizer, cov pa oxygen hauv siab -purity nitrogen tuaj yeem tsawg dua 0.1ppm. Nyob rau hauv cov nqe lus ntawm kev tiv thaiv roj, tshwj xeeb tshaj yog nyob rau hauv shipping cheeb tsam xws li loj loj integrated circuits, laser cov ntaub ntawv, optical fibers thiab aerospace cov ntaub ntawv, cov txheej txheem ntau lawm yuav tsum tau nqa tawm nyob rau hauv ib tug ultra- huv si ib puag ncig system. Piv txwv li, cov txheej txheem tsim khoom semiconductor yuav tsum tau txo cov pa oxygen hauv cov pa mus rau 1 ppm lossis qis dua, uas yuav tsum tau siv lub deoxidizer tsim nyog tshem tawm cov pa kom tau raws li qhov xav tau.

3) Syngas deoxygenation

Cov pa oxygen hauv syngas reacts nrog cov khoom carbonylation los tsim cov kua qaub uas inhibits cov tshuaj tiv thaiv carbonylation. Thiab oxidize lub cocatalyst los ua ib qho tsis yog -catalytic complex, txo cov tshuaj tiv thaiv. Ruding Nyob rau hauv cov txheej txheem ntawm octanol ntau lawm, thiaj li yuav tshem tawm carbonyl hlau thiab npib tsib xee carbonyl, yuav tsum tau npaj khoom tsim nyob rau hauv pem hauv ntej seem. Ib qho nyiaj ntawm cov pa oxygen, tab sis cov pa seem seem tuaj yeem yooj yim ua rau propylcarbonylation ntawm cov hlau muaj nuj nqis nyob rau theem tom ntej Catalyst deactivation. Txhawm rau tiv thaiv cov khoom siv hluav taws xob uas muaj txiaj ntsig zoo, cov ntsiab lus ntawm cov pa oxygen hauv cov khoom siv hluav taws xob yuav tsum tau tswj qis dua 1ppm, uas yuav tsum tau siv cov khoom siv deoxidation los nruab rau pem hauv ntej ntawm cov neeg tsim khoom.

4) Propylene deoxygenation thiab refining

Petrochemical polyethylene thiab polypropylene tsim kom muaj cov pa oxygen hauv cov pa kom tsawg dua 0.1ppm.

Vim tias cov kab mob oxygen yuav hnov ​​​​mob nrog cov catalyst, cov haujlwm catalyst yuav txo qis. Nyob rau tib lub sijhawm, nws cuam tshuam nrog cov tshuaj hauv cov tshuaj tiv thaiv los tsim cov tshuaj resinous, uas thaiv cov catalyst pores thiab cov kav dej. Deoxidizers rau olefinrefining xav kom muaj kev cuam tshuam sab xws li olefin hydrogenation thiab oxidation tsis tuaj yeem tshwm sim, uas yuav tsum tau muaj kev ua tau zoo dua deoxidizers tus neeg sawv cev.

1) Catalyst filling thiab ceev faj

Ua ntej sau, ntxuav lub reactor thiab ua qhov ntsuas cua nruj ntawm lub reactor. Raws li kev ua kom ntseeg tau tias qhov siab - txog - txoj kab nruab nrab ntawm cov txheej txheem thauj khoom yog ntau dua lossis sib npaug li 3: 1, nws raug pom zoo tias: Cov neeg ua haujlwm cuam tshuam yuav tsum hnav lub qhov ncauj qhov ntswg tiv thaiv plua plav thaum thauj khoom, thiab lub caij nplooj zeeg dawb qhov siab ntawm cov catalyst yuav tsum tsawg dua 0.5 meters. Yog tias qhov siab tshaj qhov siab tshaj 1 meter, nws raug nquahu kom ua ntej muab cov catalyst rau hauv lub hnab tsis muaj ntaub thiab xa mus rau hauv lub reactor. Lub catalyst filling yuav tsum nruj thiab txawm tias tsis muaj channeling los xyuas kom meej huab cua ntws thiab kub faib. Uniform thiab uniform txaj kuj. Tom qab sau, cov huab cua huv yuav tsum tau siv los ntxuav tawm hauv qab ntawm lub reactor kom tshem tawm cov hmoov txhaws tawm vim muaj kev cuam tshuam thiab kev sib txhuam thaum lub sijhawm ua haujlwm.

2) Catalyst tu thiab khaws cia

Kev pib thiab kaw tsis tu ncua yuav ua rau lub neej ntawm cov catalyst, yog li peb yuav tsum siv zog kom tsis txhob muaj qhov tsis tsim nyog kaw; Txo cov sulfur, chlorine, roj thiab lwm yam impurities hauv cov roj av kom ntau li ntau tau.

3) Hloov cov deoxidizer

Thaum lub deoxidizer mus txog qhov kawg ntawm nws lub neej kev pab, nws yuav tsum tau hloov. Thaum hloov, nitrogen yuav tsum tau siv ua ntej.

Siv cov pa roj los yog cov roj inert los hloov cov khoom siv hauv txaj, thiab tom qab ntawd siv nitrogen ntxiv rau qee qhov huab cua los ntxuav lub txaj, thiab maj mam nce cov pa kom txog thaum tag nrho cov pa ntxiv yog cua, cov deoxidizer tuaj yeem tshem tawm thiab hloov.
