Kusintha Kutulutsa kwa Carbon: Udindo wa CCUS mu Kukhazikika Kwamafakitale

Kukakamira kwapadziko lonse lapansi kwapangitsa kuti Carbon Capture, Utilization, and Storage (CCUS) ikhale ukadaulo wofunikira kwambiri polimbana ndi kusintha kwanyengo. CCUS imaphatikizapo njira yokwanira yoyendetsera mpweya wa carbon dioxide pogwiritsa ntchito carbon dioxide (CO2) kuchokera ku mafakitale, ndikusintha kukhala zinthu zamtengo wapatali, ndikuzisunga kuti zisatuluke mumlengalenga. Njira yatsopanoyi sikuti imangowonjezera mphamvu ya kagwiritsidwe ntchito ka CO2 komanso imatsegula njira zatsopano zogwiritsira ntchito, kutembenuza zomwe poyamba zinkawoneka ngati zinyalala kukhala zinthu zamtengo wapatali.
Pamtima pa CCUS ndikugwidwa kwa CO2, njira yomwe yasinthidwa ndi makampani monga TCWY ndi njira zawo zapamwamba zogwiritsira ntchito mpweya. TCWY's low-pressure flue gasiKugwidwa kwa CO2teknoloji ndi chitsanzo chabwino, chokhoza kuchotsa CO2 ndi chiyero kuyambira 95% mpaka 99%. Ukadaulowu ndiwosinthasintha, umapezeka m'mafakitale osiyanasiyana monga gasi wa boiler flue, mpweya wamagetsi amagetsi, mpweya wamoto, ndi mpweya wa coke oven flue.
Ukadaulo wowongolera wa MDEA decarbonization wopangidwa ndi TCWY umapititsa patsogolo ntchitoyi, ndikuchepetsa zomwe zili mu CO2 kukhala ≤50ppm yochititsa chidwi. Njirayi ndiyoyenera kuyeretsa LNG, gasi wowuma, ma syngas, ndi gasi wa uvuni wa coke, kuwonetsa kudzipereka kwakampani popereka mayankho oyenerera pazosowa zosiyanasiyana zamafakitale.
Pazofunikira zochepetsera za CO2, TCWY imapereka ukadaulo wochepetsa mphamvu yamagetsi (VPSA) decarbonization. Njira yapamwambayi imatha kuchepetsa zomwe zili mu CO2 mpaka ≤0.2%, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito popanga ammonia, kaphatikizidwe ka methanol, kuyeretsa gasi, ndi kukonza mpweya wotayira.
Zotsatira za CCUS zimapitilira kugwidwa kwa kaboni. Pogwiritsa ntchito CO2 yomwe yagwidwa ngati chakudya cha mapulasitiki osawonongeka, ma biofertilizers, ndi kukonzanso kwa gasi wachilengedwe, matekinoloje a CCUS ngati omwe adapangidwa ndi TCWY akuyendetsa chuma chozungulira. Kuphatikiza apo, kusungidwa kwa geological kwa CO2 kukugwiritsidwa ntchito kuti mafuta abwezeretsedwe bwino, zomwe zikuwonetsa maubwino osiyanasiyana a CCUS.
Pamene kuchuluka kwa ntchito za CCUS kukukulirakulirabe kuchokera ku mphamvu kupita ku mankhwala, mphamvu yamagetsi, simenti, chitsulo, ulimi, ndi magawo ena ofunikira otulutsa mpweya, ntchito yamakampani ngati TCWY imakhala yofunika kwambiri. Mayankho awo atsopano sali umboni chabe wa kuthekera kwa CCUS komanso kuwala kwa chiyembekezo cha tsogolo lokhazikika pomwe mpweya wa carbon si udindo koma gwero.
Pomaliza, kuphatikizika kwa matekinoloje a CCUS munjira zamafakitale kumayimira gawo lalikulu pankhondo yolimbana ndi kusintha kwanyengo. Ndi makampani ngati TCWY akutsogolera, masomphenya a tsogolo lopanda mpweya wa carbon akukhala otheka kwambiri, kutsimikizira kuti ndi luso lamakono ndi zatsopano, kukhazikika ndi kukula kwa mafakitale kungagwirizane.
