I-Revolutionizing Carbon Emissions: Iqhaza Le-CCUS Ekuqhubekeni Kwezimboni

Ukucindezela komhlaba wonke kokusimama kuholele ekuqhamukeni kweCarbon Capture, Utilization, and Storage (CCUS) njengobuchwepheshe obubalulekile ekulweni nokushintsha kwesimo sezulu. I-CCUS ihlanganisa indlela ebanzi yokulawula ukukhishwa kwekhabhoni ngokubamba i-carbon dioxide (CO2) ezinqubweni zezimboni, iguqule ibe yimithombo ebalulekile, futhi iyigcine ukuze ivimbele ukukhululwa komoya. Le nqubo emisha ayigcini nje ngokuthuthukisa ukusebenza kahle kokusetshenziswa kwe-CO2 kodwa futhi ivula izindlela ezintsha zokusetshenziswa kwayo, iguqule lokho okwake kwabhekwa njengodoti kube yimpahla ebalulekile.
Enhliziyweni ye-CCUS ukuthunjwa kwe-CO2, inqubo eye yashintshwa yizinkampani ezifana ne-TCWY ngezixazululo zazo ezithuthukisiwe zokuthwebula ikhabhoni. I-TCWY's low-pressure flue gasUkuthwebula kwe-CO2ubuchwepheshe buyisibonelo esihle, esikwazi ukukhipha i-CO2 ngobumsulwa obusuka ku-95% kuya ku-99%. Lobu buchwepheshe buyashintshashintsha, buthola izinhlelo zokusebenza kuzilungiselelo ezihlukene zezimboni ezifana negesi eboiler flue, ukukhishwa kwesikhungo samandla, i-kiln gas, negesi ye-coke oven flue.
Ubuchwepheshe obuthuthukisiwe be-MDEA bokukhipha ikhabhoni okwenziwa yi-TCWY buthathela inqubo igxathu elingaphezulu, lehlisa okuqukethwe kwe-CO2 kube ku-≤50ppm okuhlaba umxhwele. Lesi sixazululo sifaneleka kakhulu ukuhlanzwa kwe-LNG, igesi eyomile yokuhlanza, i-syngas, negesi ye-coke oven, okubonisa ukuzibophezela kwenkampani ekuhlinzekeni izixazululo ezihambisanayo zezidingo zezimboni ezahlukene.
Ngezidingo eziqine nakakhulu zokunciphisa i-CO2, i-TCWY ihlinzeka ngobuchwepheshe be-press swing adsorption (VPSA) decarbonization. Le ndlela ethuthukisiwe inganciphisa okuqukethwe kwe-CO2 kuze kufike ku-≤0.2%, ikwenze ilungele ukusetshenziswa ekukhiqizeni i-ammonia yokwenziwa, ukuhlanganiswa kwe-methanol, ukuhlanzwa kwe-biogas, kanye nokucutshungulwa kwegesi yokulahla umhlabathi.
Umthelela we-CCUS udlulela ngale kokuthwebula nje ikhabhoni. Ngokusebenzisa i-CO2 ethathiwe njengesitokwe sokuphakelayo samapulasitiki angaboli, izivundisi zemvelo, kanye nokutholakala kwegesi yemvelo okuthuthukisiwe, ubuchwepheshe be-CCUS obufana nalolo obuthuthukiswe i-TCWY buqhuba umnotho oyindilinga. Ngaphezu kwalokho, indawo yokugcina uwoyela ye-CO2 isetshenziswa ukuze kuthuthukiswe ukutholakala kukawoyela, okubonisa izinzuzo eziningi ze-CCUS.
Njengoba insizakalo ye-CCUS iqhubeka nokukhula isuka emandleni iye kumakhemikhali, amandla kagesi, usimende, insimbi, ezolimo, kanye neminye imikhakha ebalulekile ekhipha ikhabhoni, indima yezinkampani ezifana ne-TCWY iya ngokuya ibaluleke kakhulu. Izixazululo zabo ezintsha azizona nje ubufakazi bamandla e-CCUS kodwa futhi ziwukukhanya kwethemba lekusasa elisimeme lapho ukukhishwa kwekhabhoni kungeyona isikweletu kodwa kuwumthombo.
Sengiphetha, ukuhlanganiswa kobuchwepheshe be-CCUS ezinqubweni zezimboni kumelela igxathu elibalulekile eliya phambili ekulweni nokushintsha kwesimo sezulu. Njengoba izinkampani ezifana ne-TCWY zihola phambili, umbono wekusasa elingathathi hlangothi uya ngokuya ufinyeleleka, okufakazela ukuthi ngobuchwepheshe obufanele kanye nokusha, ukusimama nokukhula kwezimboni kungahambisana.
