Malangizo aukadaulo okhudza kuchotsa mpweya wachilengedwe m'magesi (2)

Chidule cha kuyamwa ndi kubwezeretsedwa kwa thupi

Mpweya wodyetsa ukalowa mu malire a batri, zinyalala ndi madontho a mpweyawo amachotsedwa ndi cholekanitsa chosefera, ndipo chimalowa mu nsanja yoyamwitsa kuchokera pansi. Mu nsanjayo, chimalumikizidwa ndi yankho la MDEA lopopera kuchokera pamwamba. Yankho lamadzi la MDEA (amine lean solution) limayamwa hydrogen sulfide ndi carbon dioxide mu mpweya wachilengedwe, kotero kuti hydrogen sulfide ndi carbon dioxide mu mpweya wodyetsa zichotsedwe kuti zikwaniritse zofunikira zaukadaulo za mwiniwake. Mpweya woyeretsedwa umatumizidwa kunja kwa malire kudzera mu cholekanitsa mpweya wazinthu pambuyo pochoka pamwamba pa nsanja yoyamwitsa.

Motsogozedwa ndi valavu yowongolera mulingo wamadzimadzi, mulingo wamadzimadzi pansi pa nsanja yoyamwitsa umatumiza amine wolemera ku thanki ya flash. Amine wolemera wochokera pansi pa nsanja yoyamwitsa umalowa mu thanki ya flash. Ma hydrocarbon ambiri omwe amalowa mu amine wolemera amachotsedwa ku gawo la mpweya wa flash. Motsogozedwa ndi valavu yowongolera kuthamanga, nthunzi ya flash imabwezeretsedwa ku dongosolo la mpweya wamafuta. Madzi olemera a amine amatumizidwa ku chosinthira kutentha cha amine chopanda mafuta/chopanda mafuta. Amine wotentha wopanda mafuta wochokera ku nsanja yoyamwitsa umatentha amine wolemera kuchokera ku thanki ya flash, kenako amine wolemera amalowa mu nsanja yoyamwitsa amine.

Nthunzi yopangidwa ndi reboiler yomwe ili pansi pa nsanja yokonzanso amine imalumikizana ndi yankho la amine wolemera, ndikuchotsa mpweya wa asidi kuchokera pamenepo, motero kumaliza kukonzanso kwa amine wolemera. Motsogozedwa ndi valavu yowongolera mulingo wamadzimadzi pansi pa nsanja yokonzanso amine, yankho la amine wotentha limasefukira ku chosinthira kutentha cha amine wolemera/wolemera. Pampu yolimbikitsira amine wolemera imakakamiza amine yomwe ili mu thanki ya amine buffer ndi 1.0mpa ndikuitumiza ku nsanja yoyamwitsa. Valavu yowongolera kuyenda imayikidwa pa payipi ya amine wolemera kupita ku nsanja yoyamwitsa, yomwe kudzera mwa iyo amine wolemera amalowa mu nsanja yoyamwitsa amayendetsedwa.

Pambuyo pochotsa CO2 mu mpweya wodyetsa, mpweya wodyetsa mpweya udzalowa mu mpweya wodyetsa mpweya. nsanja ya madzi m'thupi pogwiritsa ntchito mpweya wachilengedwe kuchotsa madzi.

Chipangizo chokwezedwa ndi skid-mounted decarbonization

Hengzhong imadziwika bwino pa kuchiza mitu ya gasi, kuyeretsa gasi lachilengedwe, kubwezeretsa LPG, Chomera cha LNG ndi seti ya jenereta ya gasi lachilengedwe.
