1. ASU Basic Principles thiab Applicable Scenarios
Ua ntej, cia peb luv luv xyuas cov hauv paus ntsiab lus ua haujlwm ntawm cryogenic ASU. Lub cryogenic ASU ua haujlwm los ntawm compressing, purifying (tawm cov dej noo, CO₂, thiab impurities) cua, txias nws mus rau qhov kub tsis tshua muaj siab (kwv yees li -180℃rau -200 degree), thiab tom qab ntawd sib cais cov khoom raws li lawv qhov sib txawv ntawm qhov kub thiab txias nyob rau hauv ib qho fractionation. Nitrogen (N₂), oxygen (O₂), thiab argon (Ar) tuaj yeem tso tawm raws li cov khoom siv roj (lossis kua), feem. Nyob ntawm qhov ntsuas thiab kev teeb tsa ntawm chav tsev (ib zaug-kem, ob npaug-kem, lossis triple-kem nrog argon rov qab), ASUs tau siv dav hauv steelmaking (blast furnace oxygen enrichment, converter blowing), petrochemical / gasification (yuav tsum muaj cov tshuaj tiv thaiv oxidation ntau ntawm cov iav. (oxy-}roj), chemical synthesis, electronics/semiconductors (ultra{12}}high purity nitrogen/argon), kev kho cua sov loj, thiab inert cua rauv. Yog li ntawd, ASUs feem ntau yog cov txheej txheem tseem ceeb hauv kev lag luam loj thiab nruab nrab, thiab lawv cov qauv tsim yuav tsum tau kho kom haum raws li cov kev xav tau hauv qab dej (ntau ntim ntim, purity, siab) thiab hauv zos.
2. Peev Xwm: Txiav txim siab ASU Raws li qhov xav tau.
Thawj qhov kev txiav txim siab thaum xaiv ASU yog nws lub peev xwm (piv txwv li, pes tsawg tons / tus qauv cubic meters ntawm O₂ / N₂ / Ar nws tuaj yeem tsim tau ib hnub). Lub peev xwm no yuav tsum ua kom sib haum rau qhov siab tshaj plaws kev siv roj thiab kev cia siab ntawm kev loj hlob ntawm cov txheej txheem hauv qab.
Lub peev xwm ntau ntawm cryogenic ASUs yog dav heev. Raws li kev lag luam cov ntaub ntawv, ib qho me me -Kem units tuaj yeem tsim tau kaum rau ntau pua tons ntawm oxygen ib hnub; ob -kem / nruab nrab- cov tshuab loj tuaj yeem ncav cuag ntau pua mus rau ob txhiab tons hauv ib hnub; thaum loj ntau-Kem units (nrog rau argon rov qab) tuaj yeem ua tiav ntau txhiab mus rau ntau txhiab tons ntawm O₂ ntau lawm ib hnub. Tshwj xeeb, cov ntaub ntawv qhia tau hais tias lub peev xwm ntau ntawm cov kev lag luam loj loj ASU tuaj yeem them kwv yees li 100 txog 5,000 tons / hnub ntawm O₂. Thaum xaiv qhov muaj peev xwm, qhov siab tshaj plaws (lub tshuab hluav taws xob tawg, lub tshuab hloov pauv, lub tshuab hluav taws xob, thiab lub tshuab hluav taws xob yuav xav tau cov pa oxygen ntau thaum lub sijhawm ua haujlwm siab), kev ua haujlwm tsis tu ncua (24/7), thiab kev nthuav dav yav tom ntej yuav tsum raug txiav txim siab (xws li, ntxiv cov kab ntau lawm, nce peev xwm, thiab kev ruaj ntseg backup / redundancy).
Yog li ntawd, rau loj - nplai metallurgical, petrochemical, lossis iav tej yaam num, nws yog feem ntau pom zoo kom teeb tsa nruab nrab mus rau loj ASUs (ntau pua mus rau txhiab tons / hnub O₂) kom ruaj khov thiab txo cov fwj. Rau me me - nplai lossis cov khoom siv roj (xws li, cov chaw kho cua sov, cov cua sov hauv cheeb tsam, qhov muaj peev xwm seem), cov chav me me / modular kuj tuaj yeem txiav txim siab.
3. Kev siv hluav taws xob & OPEX: Cov tsav tsheb tseem ceeb
Thaum muaj peev xwm txiav txim siab, suav cov nqi khiav lag luam (tshwj xeeb yog kev siv hluav taws xob) yog kauj ruam tseem ceeb tom ntej hauv cov txheej txheem xaiv, raws li OPEX feem ntau txiav txim siab ntev -lub sij hawm kev lag luam.

Cov kev siv hluav taws xob tshwj xeeb ntawm cov khoom siv cryogenic ASU feem ntau poob hauv thaj tsam li ntawm 250-500 kWh / tuj O₂ (los yog kwv yees li 0.3-0.6 kWh / Nm³ O₂).
Qee qhov qauv qub lossis me me tuaj yeem muaj kev siv hluav taws xob ntau dua (thiab phem dua), thaum lub zog niaj hnub no -txuag cov qauv siv kev siv cov cua sov siab, turbo-expander, thiab superior tshav kub pauv tshuab tuaj yeem txo cov kev siv hluav taws xob ntau.
Kev siv hluav taws xob tiag tiag kuj cuam tshuam los ntawm cov khoom xws li cov zis siab, cov khoom purity, thiab cov qauv tsim cov roj (txawm tias argon / N₂ rov qab los). Piv txwv li, nce tus me nyuam lub siab / compression piv los yog xav tau ntau dua purity yuav ua rau kom lub zog noj.
- Tus nqi khiav lag luam
Nyob ntawm qhov chaw, cov nqi hluav taws xob feem ntau suav rau ≈70–80% ntawm tus nqi khiav haujlwm (OPEX). Lwm cov nqi suav nrog cov neeg ua haujlwm (tus neeg ua haujlwm, kev tswj hwm), kev saib xyuas (compressor overhaul, txias lub thawv tu, lub tais / ntim hloov), catalyst / adsorbent / refrigerant (yog tias tsim nyog) hloov, nrog rau lubrication, consumables, insurance / se, thiab lwm yam. Zuag qhia tag nrho, cov khoom lag luam no suav txog kwv yees li 10-20% ntawm OPEX. Yog li ntawd, nyob rau hauv cov cheeb tsam uas muaj cov nqi hluav taws xob siab (los yog cov nqi hluav taws xob hauv zos siab), ASU cov nqi khiav lag luam tuaj yeem ua rau lub nra hnyav. Hloov pauv, yog tias qhov project nyob hauv thaj chaw uas tsis tshua muaj nqi hluav taws xob thiab pheej yig / mob siab rau lub zog (xws li, qhov ze rau cov chaw tsim hluav taws xob, kev siv hluav taws xob pov tseg / tus kheej lub zog), kev lag luam kev lag luam ntawm ASU yuav zoo dua.
Kev Lag Luam Tus Nqi Los Ntawm - cov khoom Gases (N₂/Ar/Argon)
Ntau ASUs tsis tsuas yog tsim cov pa oxygen (O₂) tab sis kuj muaj nitrogen (N₂) thiab (xaiv tau) argon (Ar). Los ntawm kev rov qab thiab muag (lossis siv hauv cov nroj tsuag) los ntawm - cov khoom siv roj, cov nqi khiav hauj lwm / nqi hluav taws xob ntawm ASU tuaj yeem raug them ib nrab. Siv argon ua piv txwv, txij li cov ntsiab lus argon hauv huab cua yog kwv yees li 0.93%, tus nqi nyiaj txiag ntawm argon zoo (los yog kua argon) tuaj yeem txo cov nqi O₂ yog tias muaj kev lag luam rau nws (xws li hauv hlau casting, electronics, inert tiv thaiv gases, thiab lwm yam). Yog li ntawd, thaum xaiv thiab txiav txim siab peev, kev tsim cov pa oxygen, ib txhij nitrogen / argon ntau lawm thiab kev siv (sab hauv lossis kev lag luam muag) yuav tsum tau txiav txim siab kom ua tiav kev lag luam tag nrho.
