1) Incazelo yenqubo
Isiqandisi esihlanganisiwe sale yunithi sizoba neziqandisi ze-methane, i-nitrogen kanye ne-hydrocarbon ezihlanziwe.
Ukusuka phezulu kwebhokisi elibandayo kungena ethangini le-buffer endaweni yokungena ye-compressor ehlanganisiwe yesiqandisi, bese iya kwi-compressor yesiqandisi. Ngemva kokucindezelwa esigabeni sokuqala, ingena esiqandisini esiphakathi kwesiteji ukuze iphole futhi ifinyezwe ngokwengxenye, bese ifakwa igesi esihlukanisweni soketshezi esiphakathi kwesigaba. Igesi ingena kwi-compressor ukuze icindezelwe okwesibili, i-refrigerant enomfutho ophezulu endaweni yokuphuma ye-compressor yesibili ingena esiqandisini sokugcina ukuze iphole futhi ifinyezwe ngokwengxenye, bese ingxube yegesi noketshezi ingena esihlukanisi sesigaba sokugcina ukuze ihlukaniswe.
Uketshezi lwesiqandisi olunomfutho ophakathi oluhlukaniswe yisihlukanisi esiphakathi kwesiteji lucindezelwa yiphampu bese lungena kwisihlukanisi ngemva kwesipholile sokugcina. Le nqubo ayibalulekile kakhulu esitshalweni esincane se-LNG.
Igesi yesiqandisi esinomfutho ophezulu kanye noketshezi lwesiqandisi oluhlukaniswe yisihlukanisi sokugcina kuthuthwa kufakwe ebhokisini elibandayo ngepayipi. Uketshezi lwesiqandisi esinomfutho ophezulu lupholiswa ku--65 ℃ ku-heat exchanger, luphothwe futhi lucindezelwe bese lubuyiselwa endleleni yokubuya ye-heat exchanger. Igesi yesiqandisi esinomfutho ophezulu iyaqhubeka ipholiswa futhi icindezelwe ku--162°C ku-heat exchanger, iphothwe futhi icindezelwe bese ibuyiselwa ku-reflux channel ye-cold end ye-heat exchanger, iphothwe phezulu, bese ihlanganiswa ne-throttle ne-depressurized liquid phase maphakathi. Igeleza phezulu futhi imunce ukushisa okuvela kugesi ehlanziwe kanye ne-high-pressure refrigerant. I-reflux refrigerant yonke iphothwe ibe yigesi futhi iphuma ekugcineni okushisayo kwe-heat exchanger. Izinga lokushisa licishe libe ngu-~36 ℃, kanti ingcindezi icishe ibe ngu-0.31MPa.A.
Ukusuka ebhokisini elibandayo kungena ithangi lokulinganisela endaweni yokungena ye-compressor yesiqandisi, bese ijikeleza futhi icindezele ukuze ifrijiwe. Izinga lokushisa le-refrigerant enomfutho ophansi ephuma ebhokisini elibandayo ngokuvamile liphakeme kunephuzu lamazolo, futhi akukho ketshezi oluzokhiqizwa. Inhloso yokusetha ithangi lokulinganisela lokungena ukuqinisekisa ukuthi uketshezi alungeni kwi-compressor ngesikhathi sokusebenza okungajwayelekile, ngesikhathi sokuqala kanye nangesikhathi sokugcwalisa kabusha i-refrigerant. Uketshezi oluqoqwe ethangini lokulinganisela lokungena alukhishwa, kodwa luphehlwa ngokwemvelo bese lubuyiselwa emjikelezweni wokufrijiwa, okungagwema ukulahlekelwa yi-refrigerant lapho uhlelo lungajwayelekile.
2) Amapharamitha okuklama
Uhlobo lwe-compressor I-Centrifugal, epholile emoyeni (igesi yenqubo)
Ingcindezi yokumunca: 0.31 MPa.A
Izinga lokushisa lokumunca: ~36 ℃
Ukucindezela kokukhipha ugesi: 3.4 MPa.A (ebhekisela ku-flange yokuphuma kwe-cooler yokugcina)
Izinga lokushisa lokukhipha ugesi: ~ 40℃ (kubhekiselwa ku-flange yokuphuma kwe-cooler yokugcina)
3) Ububanzi besicelo
I-vane yomhlahlandlela wokungena kwe-compressor kanye nokulungiswa kokungena kwe-compressor kanye nokubuyiselwa kokuphuma kusetshenziswa ukulungisa ububanzi bokulungiswa komthwalo obungu-30 ~ 110%.
