Popanda kuchitapo kanthu motsimikiza, IEA ikuyerekeza kuti mpweya wokhudzana ndi carbon dioxide udzakwera 130% mu 2050 kuchokera ku 2005.Carbon dioxide Capture and storage (CCS) ndiyo yotsika mtengo kwambiri ndipo, kwa mafakitale ena, njira yokhayo yopezera kuchepetsa mpweya.Ndipo ndi imodzi mwa njira zodalirika zochepetsera mpweya wa carbon pamlingo waukulu komanso kuchepetsa kutentha kwa dziko.
Mu 2021, European Commission inachititsa msonkhano wapamwamba wa CCUS, womwe unatsindika kufunika kopititsa patsogolo chitukuko ndi kutumizidwa kwa ntchito zamakono za CCUS pazaka khumi zikubwerazi ngati zolinga za 2030 ndi 2050 decarbonisation zikwaniritsidwe.
CCUS imaphatikizapo ukadaulo wonse wa ukadaulo wa kugwidwa kwa kaboni, kugwiritsa ntchito kaboni ndi kusungirako kaboni, ndiko kuti, mpweya woipa womwe umatulutsidwa m'makampani opanga mafakitale umatengedwa kuzinthu zomwe zitha kugwiritsidwanso ntchito podalira matekinoloje apamwamba komanso otsogola, ndikubwezeretsanso kupanga.
Izi zimawonjezera mphamvu yogwiritsira ntchito mpweya woipa wa carbon dioxide, ndipo mpweya woyeretsedwa kwambiri ukhoza "kusinthidwa" kukhala chakudya choyenera cha mapulasitiki owonongeka, biofertilizers, ndi kuwonjezereka kwa gasi wachilengedwe.Kuonjezera apo, mpweya woipa womwe umagwidwa mu geology udzakhalanso ndi gawo latsopano, monga kugwiritsa ntchito luso la kusefukira kwa carbon dioxide, kukonzanso mafuta, etc. Mwachidule, CCUS ndi njira yogwiritsira ntchito sayansi ndi luso la "mphamvu" carbon. dioksidi, kusandutsa zinyalala kukhala chuma ndikuchigwiritsa ntchito mokwanira.Malo ogwirira ntchito awonjezeka pang'onopang'ono kuchokera ku mphamvu kupita ku mafakitale a mankhwala, mphamvu yamagetsi, simenti, zitsulo, ulimi ndi madera ena ofunika kwambiri a carbon.
Low pressure flue gas CO2ukadaulo wojambula
• CO2chiyero: 95% - 99%
• Ntchito: Boiler flue mpweya, mphamvu zomera flue mpweya, uvuni mpweya, coke uvuni flue mpweya etc.
Tekinoloje yaukadaulo ya MDEA decarbonization
• CO2Zomwe zili: ≤50ppm
• Ntchito: LNG, refinery youma gasi, syngas, coke uvuni mpweya etc.
Pressure swing adsorption (VPSA) decarbonization technology
• CO2Zomwe zili: ≤0.2%
• Ntchito: Synthetic ammonia, methanol, biogas, mpweya wotayira kutayira etc.
