Introduction to Air Separation Units (ASU)
Air Separation Units (ASUs) yog qhov tseem ceeb hauv kev lag luam tsim los cais cov huab cua nyob rau hauv siab -purity oxygen, nitrogen, thiab argon los ntawm cryogenic distillation technology. Hauv kev lag luam hnyav niaj hnub, tshwj xeeb tshaj yog kev tsim cov hlau, cov khoom siv roj txhim khu kev qha ncaj qha cuam tshuam rau kev tsim khoom, cov khoom zoo, thiab kev ua haujlwm ruaj khov.
Cryogenic huab cua sib cais tseem yog cov thev naus laus zis siab tshaj plaws thiab muaj peev xwm ua kom muaj peev xwm xa cov khoom lag luam loj loj - ntim cov pa hluav taws xob xav tau los ntawm cov nroj tsuag sib xyaw ua ke.
Vim li cas cov nroj tsuag steel nyob ntawm kev siv roj av
Kev tsim cov hlau yog lub zog- cov txheej txheem hnyav uas yuav tsum muaj cov tshuaj lom neeg cov tshuaj tiv thaiv thiab tswj cov huab cua. Kev lag luam gases tsim los ntawm ASUs ua lub luag haujlwm tseem ceeb thoob plaws hauv tag nrho cov txheej txheem steelmaking:
Oxygen txhim kho combustion efficiency nyob rau hauv blast furnaces
Nitrogen muab kev tiv thaiv huab cua thaum kho cua sov
Argon txhim kho steel purity thaum lub sij hawm theem nrab refining
Yog tias tsis muaj cov khoom siv roj ruaj khov, cov hlau niaj hnub tsim tsis tuaj yeem ua tiav cov khoom lag luam siab lossis kev ua haujlwm zoo sib xws.
Cryogenic ASU Technology ua haujlwm li cas
Cryogenic ASU systems ua haujlwm los ntawm compressing thiab purifying ambient cua ua ntej txias nws mus rau qhov tsis tshua muaj kub. Los ntawm ntau-theem kev sib pauv cua sov thiab cov kab distillation, cov khoom cua sib cais raws li lawv cov ntsiab lus kub.
Cov txheej txheem tseem ceeb muaj xws li:
Cua compression thiab purification
Cryogenic cua txias los ntawm cov cua kub exchangers
Turbo expansion rau qhov kub thiab txias
Fractional distillation hauv cov thawv txias
Kev sau thiab kev faib tawm tsis tu ncua
Cov txheej txheem no ua rau cov pa purity mus txog 99.7% thiab nitrogen purity ncav cuag 99.999%, ua cryogenic ASU zoo tagnrho rau kev thov kev lag luam steel.
Cov ntawv thov tseem ceeb ntawm ASU hauv Steel Manufacturing
Blast Rauv Oxygen Enrichment
High -purity oxygen tsub kom kub combustion, txo coke noj, thiab txhim kho tag nrho cov khoom siv hluav taws xob.
Basic Oxygen Rauv (BOF) Steelmaking
Cov ntim loj ntawm cov pa oxygen yog txhaj kom tshem tawm cov impurities los ntawm cov hlau molten, ua kom cov tshuaj ua kom zoo dua qub thiab txhim kho cov hlau zoo.
Secondary Metallurgy thiab Nruam Casting
Argon roj tiv thaiv oxidation, tshem tawm cov kev suav nrog, thiab ua kom huv huv cov qauv hlau.
Kev tiv thaiv tshav kub
Nitrogen tsim inert cua uas tiv thaiv oxidation thiab decarburization thaum thermal ua.
Cov txiaj ntsig ntawm Niaj hnub ASU Systems rau Steel Producers
Niaj hnub nimno cryogenic ASU nroj tsuag muab ntau yam kev ua haujlwm zoo:
Nruam thiab ruaj khov gas mov
High purity rau advanced metallurgy
Tsawg dua - lub sij hawm tsim cov nqi
Txhim kho zog efficiency
Kev them nyiaj yug rau loj -tej kev lag luam
Raws li cov tuam txhab steel nrhiav kev ua kom zoo zog thiab qis - carbon ntau lawm, kev sib koom ua ke ntawm ASU tau dhau los ua kev nqis peev zoo.
NEWTEK's Vision for Efficient Gas Solutions
NEWTEK tsom mus rau kev xa cov kev daws teeb meem huab cua sib cais kom haum rau cov nroj tsuag niaj hnub steel. Los ntawm kev sib koom ua ke kev tsim qauv tsim kho kom zoo, lub zog- ua haujlwm tau zoo, thiab kev tswj xyuas ntse, NEWTEK txhawb nqa cov neeg tsim khoom steel kom ua tiav cov khoom siv roj ruaj khov thiab kev ua haujlwm ruaj khov.
Nrog rau kev loj hlob thoob ntiaj teb kev thov rau kev huv thiab kev tsim steel ntau dua, cov thev naus laus zis ASU yuav txuas ntxiv mus ua lub luag haujlwm tseem ceeb hauv kev tsim lub neej yav tom ntej ntawm kev lag luam roj.
