PSA thiab VPSA ob leeg ncav cuag 90 mus rau 95 vol.% band, daim nyias nyias tsis, thiab tsis muaj dab tsi luv luv ntawm lub purifier downstream lov 95% qab nthab.
Cov ntaub ntawv tseem ceeb ntawm cov ntaub ntawv oxygen purity
Oxygen purity tsis yog cov cuab yeej ruaj khov ntawm PSA, VSA lossis membrane system. Qhov tseeb purity nyob ntawm pub- huab cua, ntws tus nqi, kev khiav hauj lwm siab, lub voj voog chaw, adsorbent los yog daim nyias nyias cov yam ntxwv thiab kev teeb tsa.
Cov kab hauv kab ntawv yog vim li no rau kev siv thev naus laus zis- theem kev sib piv, tsis yog ib qho kev lees paub cov khoom siv rau txhua qhov system.
PSA purity yog xaiv tau es tsis kho. Ib qho kev tshaj tawm PSA cov ntsiab lus muaj cov qib ntawm 90, 92, 93, 94 thiab 95%, thiab ntws poob raws li qib nce: 197.4 Nm³ / h ntawm 90% nqis mus rau 179.4 Nm³ / h ntawm 95% (PSA purity qib thiab cov dej ntws, 2025). VPSA khiav mus rau lub qab nthab zoo sib xws,mus 94vol.% ntawm cov ntaub ntawv siv GASGEN luam tawm (hloov kho lub Yim Hli 2026).
Lub qab nthab yog qhov tseeb molecular, thiab nws belongs rau zeolite mechanism. Nyob rau hauv lub siab lub sieve lub zeolite nyiam adsorbs nitrogen, thiab oxygen tshuav nyob rau hauv cov khoom gas (lub molecular - loj hauv paus ntawm sieve sib cais, hloov tshiab 7 Lub Xya hli ntuj 2026). Argon yog ze txaus rau oxygen hauv qhov loj thiab adsorption tus cwj pwm uas lub sieve tsis tuaj yeem cais ob qho kev lag luam.
Vim li cas 95% yog phab ntsa, tsis yog qhov chaw:thawb yav dhau los 95% txhais tau hais tias ntxiv ib qho dej purifier, tsis tig lub tsev.
Membrane oxygen cais purity coj txawv. Ib leeg-theem O2/N2 selectivity yog me me, yog li cov khoom lag luam yog ib qho kev txhawb nqa ntau dua li qhov chaw koj hu rau hauv, thiab pub siab, ntsuas kub thiab theem suav txav qhov tshwm sim ntau dua li qhov kev tswj hwm. Qhov ntawd tsis yog qhov teeb meem uas daim ntawv thov xav tau kev txhawb nqa; nws yog qhov tsis tsim nyog uas daim ntawv thov xav tau qib.
Daim ntawv thov teev cov lim dej muaj txiaj ntsig. Cov dej khib nyiab aeration thiab aquaculture khiav ntawm 90 mus rau 93%, iav oxy- roj thiab hlau EAF enrichment ntawm 90 mus rau 95%, thiab ozone tiam ntawm 90 mus rau 95% (tsawg kawg oxygen purity los ntawm daim ntawv thov, hloov kho lub Yim Hli 2026).
Kev kho mob oxygen daws cov lus nug ntawm daim nyias nyias. LEEJ TWG hais tias PSA kev kho mob oxygen yog 93% ntxiv lossis rho tawm 3%, thaum oxygen tsim los ntawm huab cua liquefaction rau kev siv kho mob yuav tsum tsis pub tsawg dua 99.5% (WHO txoj kev kho mob oxygen purity yuav tsum tau, 2020, qauv nplooj ntawv tseem tam sim no). Rau daim ntawv thov kev kho mob oxygen, cov neeg siv yuav tsum nco ntsoov ua raws li cov cai hauv zos thiab cov qauv siv ua ntej xaiv cov khoom siv. Oxygen generator specifications ib leeg tsis txiav txim siab txog kev pom zoo.A membrane system enrichment band nyob deb tshaj 93% thiab yog li ntawd tsis tsim nyog los ntawm kev siv kho mob, thiab ib lub PSA unit tsis tuaj yeem tsuas yog thawb mus rau 99.5% yam tsis muaj downstream purifier.
Tus nqi ntawm purity yog txhua yam, tsis yog kev lag luam. Ntev adsorption theem yield ntau dua ntws ntawm qis purity; purity siab dua xav tau cua compressed ntau dua thiab hneev taw loj dua los ua nws.
Flow thiab scale: qhov twg txhua lub tshuab tsis ua lag luam?
Lub crossover zaum ntawm kwv yees li 100 Nm³ / h. Saum toj no, lub tshuab nqus tsev vacuum adsorption oxygen txuag 30 mus rau 50% ntawm lub zog PSA chav tsev yuav hlawv rau tib qhov tso zis; hauv qab no, PSA qhov kev yooj yim ntawm kev siv tshuab yeej muaj tseeb (GASGEN oxygen generator zog ntsuas, hloov kho Lub Yim Hli 2026).
Daim ntawv qhia lub hnab ntawv uas tau muab faib kom huv si. PSA generators khiav ntawm 1.5 txog 197.4 Nm³ / h (OXYBERG), thaum VPSA units hauv 80 txog 400 Nm³ / h band npog 47 txog 235 scfm, lossis 2.5 txog 12.6 tons hauv ib hnub (Atlas Copco OGV+). Loj - nplai VPSA tsob nroj muaj peev xwm ncav cuag 700 txog 10,000 Nm³ / h hauv ib lub tsheb ciav hlau, sib npaug li 25 txog 345 tons hauv ib hnub ntawm 100% O₂ (Linde Engineering).
Vim li cas PSA nres scaling smoothly? Txhua tus pej thuam ua tiav ib lub voj voog txhua txhua 60 mus rau 120 vib nas this, thiab cov dej ntws tsis txaus hloov pauv uas hloov pauv lub txaj tso tawm mus rau qhov tsis tu ncua (OXYBERG). Turndown yog li ntawd bounded los ntawm lub voj voog sij hawm thiab tsis ntim, tsis yog los ntawm kev thov ib leeg.
Lub hnab ntawv piav qhia txog daim ntawv qhia kev xav tau tom qab VPSA cov nroj tsuag loj: cov ntu kev lag luam uas lawv ua haujlwm suav nrog hlau thiab tsis yog-ferrous hlau, iav, pulp thiab ntawv, mining, combustion thiab tshuaj, lithium roj teeb cathode roasting, dej khib nyiab thiab cement oxyfuel (Linde Engineering).
Ob tug ncaj ncees caveats. Hauv qab qhov kev sib tw, VPSA me me nqa cov txheej txheem hauv daim ntawv thov tsis xav tau. Nyob rau sab saum toj ntawm ntau yam, kev sib cais cryogenic tseem yog qhov tseem ceeb.
Zog thiab tag nrho cov nqi ntawm cov tswv cuab: uas yog pheej yig dua los khiav?
VPSA yog qhov qis tshaj - kev xaiv lub zog ntawm qhov ntsuas thiab PSA qis tshaj plaws ntawm qhov ntsuas me me, yog li ntawm - qhov chaw tsim cov pa oxygen nyob ntawm qhov chaw koj zaum ntawm qhov ntws axis.
