Isitshalo se-LNG esingu-3.5~7 MMSCFD kanye nesitshalo se-LNG esifakwe e-Skid

Incazelo:

Igesi yemvelo ewuketshezi, ebizwa ngokuthi i-LNG, ifaka igesi yemvelo ibe uketshezi ngokupholisa igesi yemvelo ewuketshezi ngaphansi kwengcindezi evamile ku-162 ℃. Uketshezi lwegesi yemvelo lungasindisa kakhulu indawo yokugcina kanye neyokuthutha, futhi lunezinzuzo zenani elikhulu lama-calorie, ukusebenza okuphezulu, okuhambisana nokulinganisela kokulawulwa kwemithwalo yasemadolobheni, okuhambisana nokuvikelwa kwemvelo, ukunciphisa ukungcola kwasemadolobheni nokunye.

Ukukhiqizwa kwegesi yemvelo okuvuthiwe kuyisisekelo sokukhiqizwa kwe-LNG. Njengamanje, izinqubo zokukhiqizwa kwegesi yemvelo ezivuthiwe zifaka phakathi inqubo yokukhiqizwa kwegesi ephuma emkhathini, inqubo yokukhiqizwa kwegesi ephuma efrijini exubile kanye nenqubo yokukhiqizwa kwegesi ephuma emkhathini ene-expander.

Inqubo yokuncibilikisa igesi yemvelo ye-Cascade isebenzisa amazinga ahlukene okubilisa esiqandisini ngaphansi kwengcindezi evamile ukunciphisa izinga lokushisa lesiqandisi isinyathelo ngesinyathelo ukuze kufezwe injongo yokuncibilikisa igesi yemvelo.

Umjikelezo we-refrigerant oxubile (i-MRC) inqubo lapho izinhlobo ezingaphezu kwezinhlanu ze-refrigerant ezixubile ezinezingxenye eziningi, njenge-C1 ~ C5 Hydrocarbons kanye ne-N2, zisetshenziswa njengoketshezi olusebenzayo ukuze ziqine, ziphele futhi zande kancane kancane ukuze kutholakale umthamo we-friji emazingeni okushisa ahlukene, bese zipholisa kancane kancane futhi zenze igesi yemvelo ibe uketshezi. Inqubo yokuncibilikisa i-refrigerant exubile ihlukaniswe ngezinhlobo eziningi ezahlukene zomjikelezo we-friji.

Inqubo yokuncibilikisa uketshezi nge-expander ibhekisela enqubweni yokuncibilikisa uketshezi ngegesi yemvelo ngokusebenzisa i-refrigerant enomfutho ophezulu ukuze kufezwe ukuqandisa umjikelezo we-Claude obuyela emuva ngokwandiswa kwe-turbo expander nge-adiabatic.

Uhlelo lwenqubo luhlanganisa ikakhulukazi: iyunithi yokulawula nokulinganisa ingcindezi yegesi yokuphakelayo, iyunithi yokuhlanza igesi yemvelo kanye neyunithi yokuncibilikisa igesi yemvelo, uhlelo lokugcina isiqandisi, uhlelo lokucindezela olujikelezayo lwesiqandisi, iyunithi yokugcina kanye nokulayisha i-LNG.

Igesi yemvelo engena esiteshini idlula kuqala kuyunithi yokulawula ingcindezi kanye neyokulinganisa, eqaphela ukulawulwa kwengcindezi kanye nokulinganisa kwegesi yemvelo engenayo; Igesi yemvelo ingena kuyunithi yokuhlanza igesi yemvelo, lapho igesi yemvelo isuswa khona i-CO2, isuswe i-H2S kanye nokwelashwa kokuphelelwa amanzi emzimbeni. Inqubo ye-MDEA inconywa ukuze kususwe i-carbonization kanye nokususwa kwe-H2S, inqubo yokuphelelwa amanzi emzimbeni ngesihlungo sama-molecular enemibhoshongo emithathu NOMA inqubo yokuphelelwa amanzi emzimbeni ye-TEG inconywa ukuze kusetshenziswe ukuphelelwa amanzi emzimbeni; Futhi Kunconywa ukuthi kusetshenziswe i-BOG etholakele futhi ecindezelwe ukuze kutholakale igesi yokuvuselela;

Igesi yemvelo ehlanziwe ibe yiyunithi yokuncibilikisa igesi yemvelo, i-mixed refrigerant (inqubo yokuncibilikisa i-MRC) inconywa ekuncibilikiseni igesi yemvelo; i-LNG encibilikisiwe igcinwa ethangini lokugcina, kanti inqubo yokugcina yomoya kanye neyokushisa okuphansi inconywa ekugcineni i-LNG. Ithangi elilodwa lokugcina lomoya elinezinga lokushisa eliphansi lifakwe i-BG compressor, kanti i-BOG compressor isetshenziselwa ukucindezela i-BOG ngaphambi kokungena ku-molecular sieve dryer Regeneration, kuye ngephampu ye-cryogenic ukuze kufezwe ukufakwa.
