Khoom Description
Lub kaw lus cryogenic CO₂ capture system (tseem hu ua cryogenic CO₂ cais chav tsev) yog cov cuab yeej siv dav dav tsim kev sib xyaw ua ke roj ua ntej, cua txias, CO₂ condensation, distillation purification, thiab kua CO₂ cia.
Nws lub hauv paus ntsiab lus tseem ceeb yog ua ntej pretreat lub CO₂- muaj roj kom tshem tawm cov impurities uas yuav thaiv lossis corrode cov cuab yeej ntawm qhov kub thiab txias, ces txias cov pa kom ze rau CO₂ lub boiling point los ntawm ib tug multi-theem tub yees system-condensing CO₂ rau hauv cov kua thaum uas tsis muaj oxygen (methanes, methionable) thiab lwm yam) hauv daim ntawv gaseous rau kev sib cais.
Thaum kawg, kua CO₂ yog purified los ntawm distillation kom tau raws li cov qauv kev lag luam lossis kev cia khoom. Nws tuaj yeem txo qis CO₂ cov ntsiab lus hauv cov roj kho kom qis dua 1% (los yog tsawg dua lossis sib npaug li 0.1% rau cov xwm txheej emission nruj) thiab yog cov cuab yeej tseem ceeb rau siab - carbon capture.
Txoj cai ua haujlwm
Cov txheej txheem ua haujlwm ntawm Cryogenic Carbon Capture tuaj yeem raug sau tseg raws li 6 cov kauj ruam tseem ceeb: roj pretreatment → ua ntej - txias → cryogenic txias → CO₂ condensation & sib cais → CO₂ distillation purification → kua CO₂ cia / tso zis
Gas pretreatment:CO₂- muaj roj (piv txwv li, fais fab nroj tsuag flue roj nrog 10-15% CO₂, cov roj ntuj nrog 5-30% CO₂) ua ntej nkag mus rau hauv kev kho mob. Nws dhau los ntawm lub lim kom tshem tawm cov khoom siv (plua plav, tshauv) nrog qhov loj me dua lossis sib npaug li 5 μm, tom qab ntawd nkag mus rau hauv chav dej lub cev (molecular sieve adsorber) kom txo cov ntsiab lus dej kom qis dua 10 ppm (tsis txhob muaj dej khov uas thaiv cov kav dej ntawm qhov kub thiab txias). Rau cov roj nrog sulfur compounds (H₂S Ntau dua lossis sib npaug li 20 ppm), chav tsev desulfurization (activated carbon adsorption los yog amine scrubbing) yog ntxiv kom tshem tawm H₂S-tiv thaiv corrosion ntawm cov cuab yeej cryogenic thiab zam cov sulfur impurities hauv ntes CO₂.
Ua ntej -cooling:Pretreated gas nkag mus rau hauv lub pre-cooler, qhov twg nws pauv cov cua sov nrog tsawg- cua kub tail gases (tsis yog-condensable gases tom qab CO₂ sib cais) thiab dej txias. Cov roj kub yog txo los ntawm ambient kub (20-30 degree) mus rau 0 ~ -10 degree, ua ntej tshem tawm feem ntau ntawm cov dej noo thiab lub teeb hydrocarbons (xws li methane nyob rau hauv natural gas).
Cryogenic cua txias:Ua ntej- roj txias nkag mus rau ntau-theem cryogenic tub yees system (feem ntau yog siv propane ua ntej-cooling + mixed refrigerant cycle). Thawj theem siv propane kom txias cov pa mus rau -40 ~ -50℃; theem thib ob siv cov tub yees sib xyaw (sau ntawm nitrogen, methane, ethane, propane) kom txias cov roj ntxiv rau -55 ~ -60℃- ncav cuag qhov kub thiab txias qhov twg CO₂ condenses.
CO₂ condensation & sib cais:Cov roj cua txias txias nkag mus rau hauv lub tshuab cais. Ntawm -55 ~ -60℃thiab 1.0 ~ 6.0 MPaG, CO₂ condenses rau hauv cov kua (density ~ 1.1 g/cm³), thaum tsis yog -condensable gases (nitrogen, oxygen, residual methane) nyob twj ywm gaseous. Cov kua CO₂ yog sau rau hauv qab ntawm qhov sib cais, thiab cov roj uas tsis yog -condensable gases raug tso tawm los ntawm sab saum toj-tom qab tshav kub rov qab nyob rau hauv lub pre-cooler, lawv yog emissions (raws li ib puag ncig cov qauv) los yog recycled (xws li, natural gas Cheebtsam rov qab mus rau lub raj).
CO₂ distillation purification:Crude kua CO₂ (muaj cov kab uas tsis yog- cov pa roj carbon monoxide thiab impurities) raug xa mus rau lub tshuab distillation. Nyob rau hauv qhov txo qis (0.3 ~ 0.5 MPaG) thiab tswj qhov kub thiab txias (-50 ~ -55 degree), cov pa roj carbon monoxide impurities (nitrogen, oxygen) raug cais tawm ntawm sab saum toj ntawm tus pej thuam, thaum siab -purity kua CO₂ (purity ntau dua lossis sib npaug rau 99.0%). Rau cov xwm txheej uas xav tau ultra{13}} siab purity (xws li cov zaub mov-qib CO₂), chav tsev distillation thib ob yog ntxiv los txhim kho purity kom ntau dua lossis sib npaug li 99.9%.
Liquid CO₂ cia / tso zis:Purified kua CO₂ yog pumped rau insulated cryogenic cia tso tsheb hlau luam (tso tseg ntawm -56.6℃thiab 0.5 ~ 1.0 MPaG) rau ib ntus cia. Nws tuaj yeem raug thauj ncaj qha mus rau cov neeg siv los ntawm cov tsheb thauj khoom cryogenic (rau kev siv hauv kev lag luam xws li zaub mov carbonation, hlau vuam), lossis compressed rau supercritical CO₂ (31 degree, 7.38 MPa) rau kev thauj mus los rau thaj chaw geological los yog txhim kho cov roj rov qab (EOR).
