Ikhwalithi Ephezulu YaseChina Imboni Enkulu Yokuxutshwa Kwe-LNG - 10~30 ×104Nm3/d I-LNG Liquefaction Enkulu – Rongteng

Isingeniso

I-Liquefaction gas yemvelo, maduze ebizwa nge-LNG, ijiya igesi yemvelo ibe uketshezi ngokupholisa igesi yemvelo eyigesi ngaphansi kwengcindezi evamile ukuya ku-162 ℃. I-liquefaction yegesi yemvelo ingasindisa kakhulu indawo yokugcina neyokuthutha, futhi inezinzuzo zenani elikhulu le-calorific, ukusebenza okuphezulu, okuhambisana nokulinganisela kokulawulwa kwemithwalo yasemadolobheni, okuhambisana nokuvikelwa kwemvelo, ukunciphisa ukungcoliswa kwedolobha nokunye.

I-Liquefaction iwumgogodla wokukhiqizwa kwe-LNG kanye nesitshalo se-LNG esifakwe ngokushushuluza. Njengamanje, izinqubo ezivuthiwe zegesi yemvelo zokuncibilika ikakhulukazi zifaka inqubo yokuncibilika kwe-cascade, inqubo yokuxutshwa kwesiqandisi esiqandisini kanye nenqubo yokuncibilika nge-expander.

Inqubo ye-Cascade ye-liquefaction yegesi yemvelo isebenzisa amaphuzu ahlukene abilayo esiqandisini ngaphansi kwengcindezi evamile ukuze kuncishiswe izinga lokushisa lesiqandisi isinyathelo ngesinyathelo ukuze kufezwe injongo yokuncibilika kwegesi yemvelo.

Umjikelezo wesiqandisi oxubile (MRC) inqubo lapho izinhlobo ezingaphezu kwezinhlanu zeziqandisi ezixube izingxenye eziningi, ezifana ne-C1 ~ C5 Hydrocarbons kanye ne-N2, zisetshenziswa njengoketshezi olusebenzayo ukuze kufinyaniswe, kuhwamuke futhi kunwetshwe isinyathelo ngesinyathelo ukuze kutholwe umthamo wesiqandisi emazingeni okushisa ahlukene, bese kuthi kancane kancane kuphole futhi kuncibilike igesi yemvelo. I-Mixed refrigerant liquefaction process ihlukaniswe yaba izinhlobo eziningi ezahlukene zomjikelezo wesiqandisi.

Inqubo ye-liquefaction ene-expander isho inqubo yokuncibilika kwegesi yemvelo ngokusebenzisa isiqandisi esinengcindezi ephezulu ukuze sibone ukuhlehla kwesiqandisi somjikelezo we-Claude esinokunwetshwa kwe-adiabatic kwe-turbo expander.

Uhlelo lwenqubo ikakhulukazi luhlanganisa: iyunithi yokulawula ingcindezi yegesi ephakelayo kanye neyunithi yokulinganisa, iyunithi yokuhlanza igesi yemvelo kanye neyunithi yegesi yemvelo, isistimu yokugcina isiqandisi, uhlelo lokucindezelwa okujikelezayo kwesiqandisi, ukugcinwa kwe-LNG kanye neyunithi yokulayisha.

Ipharamitha yokuklama

Ukuklama aI-LNG Plant Skid, sidinga ipharamitha elandelayo.

1) Izimo eziyisisekelo zokuklama izitshalo:

Ukugeleza kwegesi okuphakelayo

Okuphakelayo umfutho wegesi

Izinga lokushisa legesi lokuphakelayo

Okuqukethwe kwamanzi mahhala kwegesi yokudla

2）Ukwakheka okuningiliziwe kwegesi yokuphakelayo (imvukuzane%)

3) Imininingwane yomkhiqizo:

Igesi yemvelo ewuketshezi:

Ingcindezi yokuphuma

Izinga lokushisa elipholile ngaphansi kwengcindezi yokuphuma
