Ukuhlanza Kwamini we-Natural Gas | Ukuphakamisa Nokuvuselela

Indima Ebalulekile Yokuhlanza Kwamini Kwenhlangano Yenatural Gas

U umsebenzi wesweetening esisebenzisa amine yesigas sengempela iyisibonelo esikhulu kakhulu kwemithambo yokuqinisa emindeni yamandla, isebenzisa indlela eyinkulu yokususa izigas ezimnyama—khuskusela i-hydrogen sulfide ne-carbon dioxide—kumaqozi wezinye zezigas zomhlaba. Le ndlela yokuchaphaza, oyisebenzisa izilimi zezibhalo zezinkulungwane zokubhala (alkanolamines) zokugcina lezi zinto ezingavumelekileyo ngokuchemicali, iyikwenza umkhakha wokuphatha igas elingumnyama ukuba yigas elingumthwasa, okuyifundisa imithambo yezihlalo nezinhlelo zokuhlinzekileyo zemvelo. Ubukhulu bekukhakha kwegas kwe-amine akhange kufunda kuphela; kuyilinda amathambekile asebheke phansi ukuthi angahloniphi, kuyivimba izigas ezingavumelekileyo zokuphatha ngokuphatha, futhi kuyenhance i-value yokuqinisa kwegas ngokususa izinto ezingaqinisi. Kumaqozi wezinye zezigas nezabhekayo, i-unit yokukhakha kwegas kwe-amine ibonakala njengendlela yokufika kumathuba okuthengiswa, ekwenza ukuthi iziqoqo zegas elingumnyama ezingazisekelwa zibe yizinto ezingavumelekileyo zokuthengiswa.

Izindawo zokusebenzisa ubuchwepheshe bokuthambisa ama-amine zihlanganisa lonke uchungechunge lwenani legesi yemvelo, kusukela emthonjeni kuya kumsebenzisi wokugcina. Ezimweni ezingaphambili, amasistimu okuthambisa ama-amine asetshenziswa ezikhungweni eziyinhloko zokuqoqa ukuze kusetshenziswe igesi eluhlaza evela emithonjeni eminingi ngaphambi kokuba ingene emigqonyeni yokudlulisela. Izitshalo zokucubungula igesi zisebenzisa i-amine sweetening njengesinyathelo esiyisisekelo esimisweni sazo sokuhlanza, okuqinisekisa ukuthi izinqubo ezalandela zokomiswa kwamanzi nokubuyiselwa kwe-NGL zisebenza kahle ngaphandle kokungcola. Izindawo zokuhlanza kanye nezindawo zokwenza izinto zamakhemikhali zisebenzisa i-amine sweetening ukuze zilungise igesi yokushisa kanye nemithombo yokucubungula, zivikele ama-catalyst nemishini ebucayi kuyilapho zihlangabezana nezindinganiso eziqinile zemvelo. Ngaphezu kwalokho, izakhiwo zokukhiqiza i-LNG zincike ekutholeni i-amine sweetening ukuze kufinyelelwe emazingeni aphansi kakhulu e-CO2 adingekayo ukuvimbela ukuqina ngesikhathi sokukhipha amanzi. Lokhu kusebenza kahle kwenza ubuchwepheshe bokuthambisa ama-amine bube yinto ebalulekile ekukhiqizeni igesi evamile, imisebenzi ethuthukisiwe yokubuyisa uwoyela, kanye nezinhlelo zokusebenza zokuhlanza igesi yezimboni.

Ngaphezu kwezindlela zokusebenzisa ngokodwa, ukuchitha kwe-amine kusenza kuzoba kubalulekile kwezinsizakwane ezintsha zomnotho. Izikhulisi zokuphutha kwe-biogas manje zisebenzisa izindlela zokuchitha kwe-amine eziyisikhiwe ukuqondisa i-CO2 kumaqhina ayo wezomnotho ozinconyelwe, okunikeza indlela yokufaka kumaqhina amanji wokusebenza. Amaphrojekthi okugcina nokugcina i-carbon ayisebenzisa ukuthatha kwe-amine njengotechinoloji efanele ekusunguleni i-CO2 kumaqhina amanji wokusebenza kwezindustria nezomaqhina amanji wokusebenza. Ngokuphazimula kwezinhlangano zomhlaba nokuba izinkundla zomnotho ozingavamile ziyabuyela kubalulekile kwezinkundla eziphatha, isicelo sezinkundla zokuchitha kwe-amine ezenzekile kusiza kubalulekile. Jianyang Greenfir New Energy Equipment kunikeza izinkundla zokuchitha kwe-amine ezenzekile kakhulu, izinkundla zokuvula kabusha, izinkundla zokuhlanganisa imizimba, nezinkundla zokugcina i-pressure ezenzekile kakhulu kubona izimo ezihlukene zokususa izinkundla zomnotho. Ngokwenza izinkundla ezingatholi kuphela ukuthi zihlukene ngezinkundla zokuchitha kwe-amine kodwa futhi ziqondise ukusebenza kahle, Jianyang Greenfir New Energy Equipment kusiza amaprocesa ukufikilela kwezimali zokuphatha ngokuphelele, ukuvikela izinto ezisemva kwezimali, nokwenza ukuthi umkhawulo wamagasi onke owaproceswayo uyisilinganiso esiphelele.
