Incazelo yenqubo yeyunithi ngayinye yesitshalo sokuphinda sincibilike se-BOG

I-BOG yethangi lokugcina i-LNG ingena ebhokisini elibandayo loketshezi ngemva kokucindezelwa kanye nokulinganisa, ipholiswe, incibilikiswe, futhi ipholiswe kakhulu ku-plate-fin heat exchanger, bese ibuyela ethangini lokugcina i-LNG njengomkhiqizo we-LNG ngemva kokubhoboza.

Indlela eyinhloko yobuchwepheshe yale divayisi yile:

Inqubo yokuqandisa umjikelezo we-MRC (mixed refrigerant) isetshenziselwa ukuhlanza yonke igesi ye-BOG ehlanziwe;

Lolu hlelo lwenqubo luhlanganisa:

Iyunithi yokuhlukanisa ukuhlunga igesi okuphakelayo kanye nokucindezela;

uhlelo lokuncibilikisa uketshezi lwe-LNG;

Iyunithi yokuqandisa ehlanganisiwe yesiqandisi;

1) Iyunithi yokuhlukaniswa kwegesi yokuphakelayo kanye neyokucindezela

1) Incazelo yenqubo

Igesi le-BOG lingena ku-gasifier efudumalayo yomoya kanye ne-feed gas heat exchanger, futhi ngemva kokucindezelwa, ukuhlukaniswa, kanye nokulinganisa, lingena ohlelweni loketshezi olungezansi komfula.

Imishini eyinhloko yenqubo iyi-gasifier efudumalayo emoyeni, i-feed gas heat exchanger, i-flow meter, i-booster compressor unit, njll.

2) Iyunithi yoketshezi

1) Incazelo yenqubo

Ngaphambi kokungena eyunithi yokuncibilikisa uketshezi, igesi yokuhlanza kumele ihlaziywe ukuqinisekisa ukuthi okuqukethwe kwamanzi, i-aromatics iyonke kanye nokuqukethwe kwe-mercury kuyahlangabezana nezidingo zokungena eyunithi yokuncibilikisa uketshezi. iyunithi yokwenza uketshezi.

I-BOG ehlanziwe  Igesi ingena kuqala ku-liquefaction heat exchanger ebhokisini elibandayo, ipholiswa kancane kancane yi-refrigerant ehlanganisiwe ebuyayo enokushisa okuphansi, bese ipholiswa kakhulu ibe yi--162 °C , bese ingena kusihlukanisi se-LNG ukuthola imikhiqizo ye-LNG.

Imishini eyinhloko ibhokisi elibandayo, elihlanganisa ikakhulukazi ama-plate heat exchangers, ama-separator ahlukahlukene, njll.

3) Iyunithi yokucindezela kanye nokulinganisa okuhlanganisiwe kwefriji

1) Incazelo yenqubo

Isiqandisi esihlanganisiwe sale divayisi sizokwakhiwa yiziqandisi ze-methane, i-nitrogen kanye ne-hydrocarbon ezihlanziwe.

Ukucindezela kwe-refrigerant kuqukethe i-compressor yesiqandisi esishisayo kanye ne-compressor yesiqandisi esibandayo. I-compressor yesiqandisi esishisayo ihlinzeka kakhulu ngomthamo wokupholisa wengxenye yokushisa okuphezulu, kanti i-compressor yesiqandisi esibandayo ihlinzeka kakhulu ngomthamo wokupholisa wengxenye yokushisa okuphansi.

Imishini eyinhloko i-refrigerant cycle compressor, ithangi lokulinganisa i-refrigerant, njll.

2) Amapharamitha okuklama

Umthamo wokwenza uketshezi: amathani angu-224.7/ngosuku

Uhlobo lweCompressor: I-Screw Compressor

Ama-compressor amabili (i-compressor eyodwa yesiqandisi esinokushisa okuphezulu nokuphansi ngayinye)

Ingcindezi yokumunca 0.3MPa.G

Izinga lokushisa lokumunca 40.0 ℃

Ingcindezi yokukhipha ugesi ingu-1.9MPa.G (ebhekisela ku-flange yokuphuma kwe-cooler yokugcina)

Izinga lokushisa lokukhipha ugesi 40 °C (kubhekiselwa ku-flange yokuphuma kwe-cooler yokugcina)

3) Uhla lokuzivumelanisa nezimo

50% ~ 110%.

4) Iyunithi yokushisa yebhokisi elibandayo

1) Umsebenzi wesistimu

Ngaphambi kokuqala, kubalulekile ukomisa yonke i-BOG  indlela yokugeleza kwegesi kanye nendlela yokugeleza kwefriji yedivayisi.

Ngemva kokusebenza isikhathi eside kwebhokisi elibandayo lokuncibilikisa uketshezi, i-carbon dioxide esele kanye nomswakama kugesi we-BOG ohlanziwe kuzoqongelela engxenyeni ephansi yokushisa kwebhokisi elibandayo lokuncibilikisa uketshezi, okubangela ukumelana okukhulu nokusetshenziswa kwamandla, futhi kungabangela ukuthi ibhokisi elibandayo lokuncibilikisa uketshezi lihluleke ukusebenza ngokujwayelekile. Ngakho-ke, ngemuva komjikelezo womsebenzi, ibhokisi elibandayo lokuncibilikisa uketshezi lizofudunyezwa futhi lincibilikiswe nge-nitrogen efudumele noma igesi ye-BOG.

2) Incazelo yenqubo

Igesi ye-BOG evela kunethiwekhi yamapayipi e-nitrogen ishiswa ngogesi ibe ngama-degrees angu-60-70 ℃ , bese ingena eziteshini zokugeleza ezihamba phambili nezibuyela emuva zegesi yokuphakelayo kanye neziteshi zokugeleza ezihamba phambili nezibuyela emuva zefriji ebhokisini elibandayo loketshezi ukuze kufudunyezwe, bese ishiswa kusukela ekukhishweni kwebhokisi elibandayo.

URongteng ugxile ekwelapheni izinsiza zemithombo yegesi, ukuhlanzwa kwegesi yemvelo, ukubuyiswa kwe-LPG, isitshalo se-LNG kanye isethi yejeneretha yegesi yemvelo.
