Incazelo yenqubo yeyunithi ngayinye ye-BOG reliquefying plant

I-BOG yethangi lokugcina le-LNG ingena ebhokisini elibandayo le-liquefaction ngemva kokucindezelwa kanye ne-metering, ipholiswe, ifakwe uketshezi, futhi ipholile kakhulu ku-plate-fin heat exchanger, bese ibuyela ethangini lokugcina le-LNG njengomkhiqizo we-LNG ngemva kokudonsa.

Indlela yobuchwepheshe eyinhloko yalo mshini yile:

Inqubo yesiqandisi yomjikelezo we-MRC (isiqandisi esixubile) isetshenziselwa ukucwilisa yonke igesi ye-BOG ehlanziwe;

Lolu hlelo lokusebenza luhlanganisa:

Ukuhlukaniswa kokuhlunga kwegesi okuphakelayo kanye neyunithi yokucindezela;

Uhlelo lwe-LNG liquefaction;

Iyunithi yesiqandisi ehlanganisiwe;

1) Okuphakelayo kokuhlukaniswa kwegesi kanye neyunithi yokucindezela

1) Incazelo yenqubo

I-BOG gas ingena ku-gasifier eshisayo yomoya kanye ne-feed gas heat exchanger, futhi ngemva kokucindezelwa, ukuhlukaniswa, kanye ne-metering, ingena ohlelweni lwe-liquefaction engezansi.

Imishini yenqubo eyinhloko i-gasifier eshisisa umoya, i-feed gas heat exchanger, imitha yokugeleza, i-booster compressor unit, njll.

2)Iyunithi ye-Liquefaction

1) Incazelo yenqubo

Ngaphambi kokungena kuyunithi yoketshezi, igesi yokuhlanza kufanele ihlaziywe ukuze kuqinisekiswe ukuthi okuqukethwe kwamanzi, ingqikithi ye-aromatics kanye ne-mercury kuhlangabezana nezidingo zokungenaiyunithi ye-liquefaction.

I-BOG ehlanziwe Igesi iqala ingena ku-liquefaction heat exchanger ebhokisini elibandayo, ipholiswa kancane kancane isiqandisi esihlanganisiwe sezinga lokushisa eliphansi esibuyayo, bese sipholile kakhulu siye ku -162°C, bese ingena kusihlukanisi se-LNG ukuze uthole imikhiqizo ye-LNG.

Imishini eyinhloko yibhokisi elibandayo, elihlanganisa ikakhulukazi ama-plate heat exchangers, ama-separators ahlukahlukene, njll.

3) I-Mixed refrigerant compression and proportioning unit

1) Incazelo yenqubo

Isiqandisi esixubile salolu cingo sizokwakhiwa nge-methane ehlanzekile, i-nitrogen ne-hydrocarbon refrigerants.

Ukucindezelwa kwesiqandisi kuqukethe i-compressor yesiqandisi esishisayo kanye ne-compressor yokugcina epholile. I-compressor yesiqandisi esishisayo ihlinzeka ngokuyinhloko amandla okupholisa okuphela kwezinga lokushisa eliphezulu, futhi i-compressor yesiqandisi yokugcina ebandayo inikeza ngokuyinhloko umthamo wokupholisa wengxenye yezinga lokushisa eliphansi.

Imishini eyinhloko yi-compressor yomjikelezo wesiqandisi, ithangi le-refrigerant proportioning tank, njll.

2) Design nemingcele

Amandla okuncibilika: 224.7 amathani/d

Uhlobo lwe-Compressor: I-Screw Compressor

Ama-compressor ama-2 (i-compressor yesiqandisi engu-1 ephezulu naphansi ngayinye)

Ingcindezi yokudonsa 0.3MPa.G

Izinga lokushisa lokumunca 40. 0℃

Ingcindezi ye-exhaust engu-1.9MPa.G (ibhekisela ekuphumeni kwe-flange yesipholile sokugcina)

Exhaust lokushisa 40°C(ebhekisela ekuphumeni kwe-flange ye-cooler yokugcina)

3) Ibanga lokuzivumelanisa nezimo

50% ~ 110%.

4) Iyunithi yokushisa yebhokisi elibandayo

1) Umsebenzi wesistimu

Ngaphambi kokuqala kokuqala, kuyadingeka ukomisa yonke i-BOG indlela yokugeleza kwegesi kanye nendlela yokugeleza kwesiqandisi sedivayisi.

Ngemuva kokusebenza isikhathi eside kwebhokisi elibandayo le-liquefaction, i-carbon dioxide esele kanye nomswakama ku-BOG gas ehlanzekile izoqoqa engxenyeni ephansi yokushisa yebhokisi elibandayo le-liquefaction, okubangela ukumelana nokwanda nokusetshenziswa kwamandla, futhi kungase kubangele ukubanda kwe-liquefaction. ibhokisi ukwehluleka ukusebenza ngokujwayelekile. Ngakho-ke, Emjikelezweni Womsebenzi, ibhokisi elibandayo le-liquefaction lizofudunyezwa futhi lincibilikiswe nge-nitrogen efudumele noma igesi ye-BOG.

2) Incazelo yenqubo

Igesi ye-BOG evela kunethiwekhi yamapayipi e-nitrogen ifudunyezwa ngogesi ibe ngu-60~70℃ , bese ingena kumashaneli okugeleza aya phambili nangemuva egesi ephakelayo kanye namashaneli okugeleza okuya phambili nangemuva kwesiqandisi ebhokisini elibandayo le-liquefaction ukuze lishise, bese lishiswa ngokuphuma kwebhokisi elibandayo.

I-Rongteng igxile ekwelapheni i-wellhead field yegesi, ukuhlanzwa kwegesi yemvelo, ukutakula kwe-LPG, imboni ye-LNG kanyeisethi yejeneretha yegesi yemvelo.
