Thaum xaiv cov khoom siv oxygen, cov tuam txhab lag luam feem ntau ntsib cov lus nug zoo: Puas yog nws yooj yim dua rau nruab rau ntawm -site cryogenic cua cais chav tsev (ASU), lossis tsuas yog yuav cov pa oxygen (LOX) thiab khaws cia rau hauv lub tank? Tsis muaj cov lus teb thoob ntiaj teb, raws li kev siv cov pa oxygen, cov qauv siv, thiab cov hluav taws xob sib txawv ntawm ib qho chaw mus rau lwm qhov. Hauv kev xyaum, ntau tus neeg tsis nkag siab tus qauv nqi ntawm ob txoj hauv kev no -xws li kev kwv yees qhov rov qab los ntawm kev nqis peev ntawm ASU lossis underestimating lub sij hawm ntev - cov nqi ntawm cov pa oxygen mov.
Txoj Kev Logic Tom Qab Ob Txoj Kev Muab Oxygen
Cryogenic huab cua sib cais tseem ceeb siv cua ua khoom noj. Los ntawm compression, purification, tshav kub pauv, thiab distillation, oxygen yog cais tawm ntawm huab cua. Txoj hauv kev no yuav tsum muaj peev txheej ua ntej kev nqis peev, tab sis cov nuj nqis tom qab raug txwv rau hluav taws xob thiab kev saib xyuas - oxygen yog "tsim" zoo ntawm qhov chaw.
Cov kua oxygen tank muab tau yooj yim dua. Cov khoom siv muaj lub tank cia cryogenic thiab vaporizer. Oxygen tau yuav ua kua, thiab lub tsheb thauj khoom thauj khoom rov qab rau lub tank cia raws li lub sijhawm teem tseg.
Hauv qhov tseeb, ib txoj hauv kev yog cov cuab yeej cuab tam - hnyav, thaum lwm qhov yog kev ua haujlwm - hnyav. Cov cuab yeej cuab tam- hnyav txhais tau tias ua qhov peev txheej pib loj thiab rov qab los ntawm lub sijhawm. Kev ua haujlwm- hnyav txhais tau tias them tsis tu ncua- txhua tuj ntawm cov pa oxygen siv yuav raug nqi ncaj qha. Nkag siab qhov sib txawv ntawm qhov tseem ceeb no yog qhov tseem ceeb ua ntej sib piv cov nqi.
Yuav ua li cas xam tag nrho cov nqi kom raug
Txhawm rau txiav txim siab seb qhov kev xaiv twg yuav txuag tau nyiaj ntau dua, yuav tsum tau saib ntev -. Tsis yog kev cia siab rau cov qauv nruj, cov kev tshuaj ntsuam hauv qab no tsom mus rau ntau qhov tiag - tus nqi tsav tsheb hauv ntiaj teb.
Khoom siv peev txheej
Ib qho ua tiav cryogenic ASU tuaj yeem nyob ntawm ntau pua txhiab mus rau kaum lab ntawm US las, nyob ntawm seb muaj peev xwm tsim cov pa oxygen. Hauv qhov sib piv, lub kaw lus ua kua oxygen tank - suav nrog lub tank cia (txij li kaum mus rau pua pua cubic meters), vaporizer, thiab cov khoom siv tswj lub siab- feem ntau raug nqi ntawm ntau kaum txhiab thiab ob puas txhiab daus las. Nyob rau hauv cov nqe lus ntawm kev nqis peev thawj zaug, cov kua oxygen tank yeej yeej.
Cov nqi hluav taws xob rau kev ua haujlwm
Qhov no yog tus nqi tseem ceeb tshaj plaws rau ASUs. Cov compressors, expanders, thiab boosters nyob rau hauv ib tug ASU yog lub hwj chim -intensive. Kev siv hluav taws xob ib lub cubic meter ntawm gaseous oxygen txawv heev nyob ntawm tus nqi zog hauv zos. Rau kev sib cuam tshuam lossis hloov pauv cov pa oxygen xav tau, ASU tuaj yeem ua haujlwm ntawm cov khoom qis rau lub sijhawm ntev, ua kom lub zog siv zog ntau ntxiv. Lub tshuab ua kua oxygen lub tank siv yuav luag tsis muaj hluav taws xob- tsuas yog me me rau vaporization thiab kev tswj siab, uas yog qhov tsis txaus ntseeg.
Kua Oxygen Purchase Nqi
LOX tus nqi hloov pauv nrog kev ua lag luam thiab muaj kev cuam tshuam loj heev los ntawm kev thauj mus los. Rau cov neeg siv nyob deb ntawm LOX cov chaw tsim khoom, cov nqi thauj khoom nce ntxiv. Tsis tas li ntawd, LOX muaj tus nqi evaporation ntawm ntuj tsim - txawm tias lub tank insulated zoo npaum li cas, ob peb feem pua ntawm cov kua oxygen evaporates txhua hnub. Qhov kev poob no yog tus nqi tiag tiag, tsis tu ncua.
Kev Ua Haujlwm thiab Kev Kho
Lub cryogenic ASU xav kom cov neeg ua haujlwm tau kawm paub txog cov txheej txheem. Nws tsis yog txoj haujlwm rau cov neeg ua haujlwm saib xyuas dav dav. Kev khiav hauj lwm ntawm cov kab distillation, molecular sieve regeneration cycles, thiab expander txij nkawm tag nrho xav tau kev txawj ntse. Lub kaw lus ua kua oxygen tank muaj ntau qhov kev tswj hwm qis dua - tsuas yog saib xyuas cov kua dej ib ntus thiab teem caij thauj lub tank rov qab. Cov nqi kho mob kuj tseem qis dua rau cov tshuab tank, vim ASUs muaj cov cuab yeej sib hloov ntau dua thiab ntau dua kev kho ntau zaus thiab cov nqi.
Oxygen Consumption Scale Determines cost-Effectiveness
Raws li cov ntaub ntawv kev ua haujlwm tiag tiag, muaj qhov pib nyuaj. Thaum qhov nruab nrab txhua hnub noj cov pa oxygen qis dua ib theem, lub tshuab ua kua oxygen tank muab cov nqi qis dua. Qhov no yog vim qhov kev nqis peev ruaj khov thiab kev siv hluav taws xob hauv paus ntawm ASU ua rau ib qho - cubic - meter tus nqi siab heev thaum siv tsawg.
Hloov pauv, ib zaug oxygen noj ntau dua ib qho kev ntsuas, tus nqi qis tshaj ntawm ASU yuav tshwm sim. Tus nqi ntawm tus kheej - tsim cov pa oxygen maj mam poob qis dua qhov uas tau yuav cov pa oxygen.
Qhov chaw pib no tsis kho. Nws nyob ntawm tus nqi hluav taws xob, tus nqi LOX hauv zos, thiab lub sijhawm txo cov khoom siv. Hauv cov cheeb tsam uas muaj cov nqi hluav taws xob tsawg thiab cov nqi LOX siab, qhov pib hloov mus rau sab laug- txhais tau tias qhov ntsuas me me ntawm kev siv ua kom pom tseeb ASU. Qhov twg hluav taws xob kim thiab LOX pheej yig thiab yooj yim muaj, qhov pib hloov txoj cai.
Overlooked Tus Nqi Nkaus
Ntau lub tuam txhab sib piv tsuas yog cov nqi hluav taws xob thiab LOX cov nqi tsev, tsis muaj peb yam tseem ceeb.
1. Oxygen Demand fluctuation
Qee qhov chaw siv cov pa me me feem ntau ntawm lub sijhawm tab sis xav tau lub ntim loj thaum lub sijhawm tsim khoom tshwj xeeb. ASU tawm tsam nrog tus qauv no-xws li yuav tsum tau ntxiv cov tso tsheb hlau luam thiab cov tshuab surge lossis khiav lub tsev ntawm qhov ua tau zoo. Lub tshuab ua kua oxygen tank yog ib txwm haum rau cov xwm txheej zoo li no, vim tias lub tank cia nws tus kheej ua raws li qhov tsis zoo.
2. Cov kev xav tau txuas ntxiv
Yog hais tias ib tug cryogenic ASU kaw, restarting thiab ncav cuag 合格 oxygen purity feem ntau yuav siv sij hawm ob peb teev -qee zaum tshaj kaum teev. Rau cov txheej txheem uas tsis tuaj yeem zam qhov kev cuam tshuam cov pa oxygen, ASU xav tau kev daws teeb meem, uas ua rau cov nqi nce. Lub tshuab ua kua oxygen lub tank muab cov pa oxygen tam sim ntawd - tsuas yog qhib lub valve - tsuav yog khaws cia qib tank.
3. Site thiab Utilities
Cryogenic ASUs xav tau thaj av tseem ceeb thiab muaj cov kev cai nruj rau cov hauv paus, kev tiv thaiv hluav taws, thiab cov tshuab hluav taws xob. Qee qhov chaw cog qoob loo uas twb muaj lawm tsuas tuaj yeem tsis tuaj yeem ua raws li ASU yam tsis muaj nqi ua haujlwm hauv pej xeem. Lub tshuab ua kua oxygen tank muaj qhov taw qhia me me, cov kev xaiv yooj yim layout, thiab ntau qhov chaw qis dua.
Kev txiav txim siab pom zoo- Ua cov kauj ruam
Kauj Ruam 1: Sau cov ntaub ntawv siv oxygen tiag tiag.
Tsis txhob cia siab rau kev tsim lossis theoretical qhov tseem ceeb. Saib cov ntaub ntawv tiag tiag los ntawm 6 txog rau kaum ob lub hlis dhau los, suav nrog kev siv nruab nrab txhua hnub, qhov siab tshaj plaws thiab qhov xav tau tsawg kawg nkaus, thiab lub sijhawm faib khoom siv.
Kauj Ruam 2: Tshawb xyuas cov nqi hluav taws xob hauv zos thiab xa cov nqi LOX.
Ob daim duab no txiav txim siab seb qhov nyiaj tshuav nyiaj li cas nyob.
Kauj Ruam 3: Khiav kaum- xyoo tag nrho cov nqi suav.
Xws li cov cuab yeej siv peev, cov nqi teeb tsa, cov nqi hluav taws xob txhua xyoo, cov nqi yuav khoom LOX txhua xyoo, kev ua haujlwm, kev saib xyuas, thiab cov khoom seem seem. Tsis txhob saib tsuas yog thawj peb lub xyoos xwb- cov cuab yeej siv hauv kev lag luam feem ntau muaj kev pabcuam lub neej ntawm kaum xyoo lossis ntau dua.
Kauj Ruam 4: Xav txog kev xav tau cov pa oxygen nyob rau peb mus rau tsib xyoos tom ntej.
Yog tias koj cov nroj tsuag nthuav dav thiab kev xav tau oxygen tuaj yeem ua ob npaug, txhim kho ASU loj dua me ntsis tam sim no yuav raug nqi ntau dua - zoo dua li siv LOX tso tsheb hlau luam tam sim no thiab hloov mus rau ASU hauv ob peb xyoos.
