Qhov sib txawv tseem ceeb ntawm carbon capture thiab cia thiab carbon sequestration yog carbon capture thiab cia koom nrog ntes, thauj, thiab khaws cia carbon dioxide, thaum carbon sequestration tsuas yog khaws cia carbon dioxide rau lub sij hawm ntev.
Carbon yog cov khoom siv tshuaj lom neeg thiab yog lub hauv paus tsim thaiv ntawm biomolecules. Nws muaj xws li cov khoom khib nyiab, kua, thiab cov ntawv gaseous hauv ntiaj teb. Cov pa roj carbon dioxide yog cov pa roj carbon monoxide. Thaum cov pa roj carbon sib xyaw nrog oxygen molecules, nws tsim cov pa roj carbon dioxide. Cov pa roj carbon dioxide hu ua lub tsev cog khoom roj, vim nws ntxiab cua sov thiab ua rau muaj kev hloov pauv huab cua. Kev tsim cov pa roj carbon dioxide yog qhov tshwm sim ntawm ob qho tib si xwm thiab tib neeg kev ua ub no. Lawm, carbon dioxide yog tsim los ntawm decomposing organic teeb meem, hluav taws kub hav zoov, thiab lwm yam. Cov neeg tsim carbon dioxide yog tsim los ntawm hlawv thee, roj, thiab natural gas los tsim lub zog. Yog li ntawd, cov kws tshawb fawb tau tsim ntau yam txheej txheem los ntes thiab khaws cov pa roj carbon dioxide los tiv thaiv lub ntiaj teb huab cua sov.
Carbon Capture thiab Cia yog dab tsi?
Carbon capture and storage (CCS) yog cov txheej txheem uas ntes cov pa roj carbon dioxide, thauj nws mus rau qhov chaw cia, thiab tso rau hauv qhov chaw uas nws tsis nkag mus rau hauv qhov chaw. Nws suav nrog kev ntes, thauj, thiab tso cov pa tawm hauv tsev cog khoom los ntawm cov chaw siv roj hluav taws xob thiab kev lag luam. Feem ntau, carbon dioxide raug ntes los ntawm cov ntsiab lus loj xws li cov nroj tsuag hluav taws xob thiab khaws cia hauv av. Lub hom phiaj tseem ceeb ntawm CCS yog los tiv thaiv kev tso tawm cov pa roj carbon dioxide los ntawm kev lag luam loj thiab hnyav txhawm rau txo qis emissions ntawm tsev cog khoom gases rau hauv cov huab cua. Cov pa roj carbon dioxide cia tau hais tias yog nyob rau hauv qhov sib sib zog nqus geological tsim los yog hauv cov ntaub ntawv ntxhia carbonate.

CCS Technology
Txoj hauv kev zoo tshaj plaws los ntes cov pa roj carbon dioxide yog los ntawm cov ntsiab lus. Cov ntsiab lus no yog kev lag luam uas tso tawm cov pa roj carbon dioxide siab, cov nroj tsuag roj hluavtaws, cov chaw siv hluav taws xob biomass, thiab cov nroj tsuag fossil roj-based hydrogen. Muaj ntau cov txheej txheem tam sim no los ntes cov pa roj carbon dioxide. Qhov no poob rau hauv peb pawg: post-combustion carbon capture, pre-combustion carbon capture, thiab oxy-fuel combustion systems. Tom qab combustion carbon capture yog thaum cov pa roj carbon dioxide yog sib cais los ntawm lub tso pa nyob rau hauv ib tug combustion txheej txheem. Pre-combustion carbon capture gasifies cov roj thiab cais cov pa roj carbon dioxide. Oxy-roj combustion carbon capture tso cai rau cov roj hlawv nyob rau hauv ib tug ntshiab oxygen ib puag ncig uas ua rau ib tug ntau concentrated kwj ntawm carbon dioxide emission. Thaum cov pa roj carbon dioxide raug ntes, nws yog compressed rau hauv cov kua. Tom qab ntawd nws raug thauj los ntawm cov kav dej, nkoj, lossis lwm lub tsheb mus rau qhov chaw cia khoom tsim nyog. Thaum kawg, cov pa roj carbon dioxide yog txhaj rau hauv qhov tob geological tsim los yog hauv av. Nws yog khaws cia rau lub sijhawm ntev, tiv thaiv kev tso tawm carbon dioxide rau hauv qhov chaw. Cov chaw khaws cia no suav nrog cov qub roj thiab roj reservoirs, coal beds, thiab sib sib zog nqus saline formations.
Kev Sequestration Carbon yog dab tsi?
Carbon sequestration yog tus txheej txheem ntawm kev ntes mus ntev thiab khaws cia cov pa roj carbon dioxide txhawm rau tiv thaiv kom tsis txhob nkag mus rau qhov chaw. Qhov no tso cai rau kom ruaj khov ntawm cov pa roj carbon monoxide hauv cov khoom thiab cov ntaub ntawv yaj kom tsis txhob muaj qhov kub thiab txias. Carbon sequestrations yuav ua tau lom thiab geological.

Txoj Kev Sequestration Carbon
Kev cais cov pa roj carbon monoxide yog cov txheej txheem khaws cov pa roj carbon dioxide hauv cov nroj tsuag xws li cov nyom thiab hav zoov, av, thiab dej hiav txwv. Geological carbon sequestration yog khaws cia cov pa roj carbon dioxide nyob rau hauv underground geologic formations. Feem ntau, cov pa roj carbon dioxide raug ntes los ntawm cov hlau lossis cov cement kev lag luam lossis cov khoom siv hluav taws xob xws li cov chaw tsim hluav taws xob. Cov pa roj carbon dioxide ntes tau no ces txhaj rau hauv cov pob zeb ntxeem tau rau lub sijhawm ntev. Carbon sequestration tseem cuam tshuam rau lwm lub tsev cog khoom xws li methane thiab nitrous oxide. Cov pa roj no tseem raug ntes thiab khaws cia thaum ua liaj ua teb xws li kev ua liaj ua teb thiab qoob loo loj hlob. Nitrous oxide feem ntau yog tso tawm ntawm cov chiv, thiab methane tso tawm los ntawm cov tsiaj nyeg. Cov pa roj carbon sequestration kuj ua rau cov av, huab cua, dej, thiab cov tsiaj qus thaj chaw zoo.
Dab tsi yog qhov zoo sib xws ntawm Carbon Capture thiab Storage thiab Carbon Sequestration?
- Cov no koom nrog kev ntes thiab khaws cov pa roj carbon dioxide.
- Ob leeg muaj lub hom phiaj tib yam - tiv thaiv cov pa roj carbon dioxide kom nkag mus rau hauv huab cua.
Qhov txawv ntawm Carbon Capture thiab Cia thiab Carbon Sequestration yog dab tsi?
Carbon capture thiab cia koom nrog ntes, thauj, thiab tso pa tawm carbon dioxide, thaum carbon sequestration yuav ntes thiab khaws cia carbon dioxide. Qhov no yog qhov sib txawv tseem ceeb ntawm carbon capture thiab cia thiab carbon sequestration.
Cov lus qhia hauv qab no qhia txog qhov sib txawv ntawm kev ntes carbon thiab khaws cia thiab carbon sequestration hauv daim ntawv teev npe.
Summary – Carbon Capture vs Storage and Carbon Sequestration
Cov pa roj carbon yog cov tshuaj lom neeg, thiab cov pa roj carbon dioxide yog cov pa roj carbon monoxide. Cov pa roj carbon dioxide nce qhov kub thiab txias hauv qhov chaw. Carbon capture thiab cia los yog CCS yog cov txheej txheem uas ntes cov pa roj carbon dioxide emissions, thauj mus rau qhov chaw cia, thiab tso nws nyob rau hauv ib txoj kev uas nws tsis nkag mus rau hauv cov huab cua. Nws tiv thaiv kev tso tawm cov pa roj carbon dioxide los ntawm kev lag luam loj thiab hnyav txhawm rau txo cov emissions ntawm tsev xog paj gases nkag mus rau hauv cov huab cua. Carbon sequestration yog cov txheej txheem ntawm kev ntes thiab khaws cov pa roj carbon dioxide mus ntev kom tsis txhob nkag mus rau qhov chaw. Qhov no tso cai rau kev ruaj khov ntawm cov pa roj carbon monoxide hauv cov khoom thiab cov ntaub ntawv yaj kom tsis txhob muaj huab cua nce qhov kub thiab txias. Ob leeg muaj tib lub hauv paus ntsiab lus, kom tsis txhob muaj cov pa roj carbon dioxide nkag mus rau hauv qhov chaw. Yog li, qhov no qhia txog qhov sib txawv ntawm kev ntes carbon thiab khaws cia thiab carbon sequestration.
