10~30 ×10⁴I-Nm³/d Uketshezi Olukhulu lwe-LNG

Isingeniso

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.

Uketshezi luyisisekelo sokukhiqizwa kwe-LNG kanye nesitshalo se-LNG esifakwe kuma-skid. Njengamanje, izinqubo zoketshezi lwegesi yemvelo ezivuthiwe zifaka phakathi inqubo yoketshezi lwe-cascade, inqubo yoketshezi lwe-refrigerant exubile kanye nenqubo yoketshezi nge-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.

Ipharamitha yokuklama

Ukuze siklame i-LNG Plant Skid, sidinga ipharamitha elandelayo.

1) Izimo eziyisisekelo zomklamo wesitshalo:

Ukugeleza kwegesi okuphakelayo

Umfutho wegesi wokudla

Izinga lokushisa legesi lokuphakelayo

Okuqukethwe kwamanzi kwamahhala kwegesi yokudla

2） Ukwakheka kwegesi okuphakelayo okuningiliziwe (i-mole%)

3) Imininingwane yomkhiqizo:

Igesi yemvelo encibilikisiwe:

Ingcindezi yesitolo

Izinga lokushisa elingaphansi kokupholisa ngaphansi kwengcindezi yokuphuma

Okuqukethwe okuphezulu kwe-nitrogen

Okuqukethwe okuphezulu kwe-carbon dioxide
