Kufotokozera kwa njira iliyonse ya chomera chosinthira madzi cha BOG

BOG ya thanki yosungiramo LNG imalowa m'bokosi lozizira la liquefaction pambuyo popanikizika ndi kuyeza, imaziziritsidwa, kusungunuka, ndikuzizira kwambiri mu chosinthira kutentha cha plate-fin, ndikubwerera ku thanki yosungiramo LNG ngati chinthu cha LNG pambuyo poyimitsa.

Njira yayikulu yaukadaulo ya chipangizochi ndi:

Njira yoziziritsira ya MRC (mixed refrigerant) imagwiritsidwa ntchito kusungunula mpweya wonse wa BOG woyeretsedwa;

Dongosolo la ndondomekoyi limaphatikizapo:

Kupatukana kwa mpweya wothira chakudya ndi kupanikizika;

dongosolo la LNG lothira madzi;

Chipinda choziziritsira chosakanikirana;

1) Gawo lolekanitsa mpweya ndi kupanikizika kwa chakudya

1) Kufotokozera njira

Mpweya wa BOG umalowa mu chosinthira kutentha cha gasi chotenthetsera mpweya ndi mpweya wodyetsa, ndipo pambuyo popondereza, kulekanitsa, ndi kuyeza, umalowa mu dongosolo la liquefaction lotsikira pansi.

Zipangizo zazikulu zogwiritsira ntchito ndi gasifier yotenthetsera mpweya, chosinthira kutentha kwa mpweya wodyetsa, choyezera kuyenda, chipangizo cholimbikitsira compressor, ndi zina zotero.

2) Chigawo chothira madzi

1) Kufotokozera njira

Musanalowe mu chipangizo choyeretsera madzi, mpweya woyeretsera uyenera kufufuzidwa kuti zitsimikizire kuti madzi, zonunkhira zonse, ndi kuchuluka kwa mercury zikukwaniritsa zofunikira zolowera mu chipangizocho. chipangizo choyeretsera madzi.

BOG yoyeretsedwa  Gasi limalowa koyamba mu chosinthira kutentha cha liquefaction mu bokosi lozizira, kenako limaziziritsidwa pang'onopang'ono ndi refrigerant yosakanikirana yotsika kutentha, kenako limaziziritsidwa kwambiri kufika pa -162 °C , kenako imalowa mu LNG separator kuti ipeze zinthu za LNG.

Zipangizo zazikulu ndi bokosi lozizira, lomwe makamaka limaphatikizapo zosinthira kutentha kwa mbale, zolekanitsa zosiyanasiyana, ndi zina zotero.

3) Kukanikiza ndi kugawa chiŵerengero cha zinthu zosakaniza mufiriji

1) Kufotokozera njira

Firiji yosakanikirana ya chipangizochi idzapangidwa ndi mafiriji oyeretsedwa a methane, nayitrogeni ndi hydrocarbon.

Kukanikiza kwa refrigerant kumakhala ndi compressor yoziziritsa kutentha ndi compressor yoziziritsa yozizira. Compressor yoziziritsa kutentha imapereka mphamvu yoziziritsira kutentha kwapamwamba, ndipo compressor yoziziritsa yozizira imapereka mphamvu yoziziritsira kutentha kwa gawo lozizira.

Zipangizo zazikulu ndi refrigerant cycle compressor, refrigerant proportional tank, ndi zina zotero.

2) Magawo a kapangidwe

Kuchuluka kwa madzi: matani 224.7/tsiku

Mtundu wa kompresa: Kokaniza kompresa

Ma compressor awiri (compressor imodzi yoziziritsira kutentha kwambiri komanso kotsika)

Kuthamanga kwa kuyamwa 0.3MPa.G

Kutentha kwa kuyamwa 40.0 ℃

Kuthamanga kwa utsi 1.9MPa.G (kutanthauza flange yotulutsira mpweya ya choziziritsira chomaliza)

Kutentha kwa utsi 40 °C (ponena za flange yotulutsira madzi ya choziziritsira chomaliza)

3) Mtundu wa kusintha

50% ~ 110%.

4) Chipinda chotenthetsera cha bokosi lozizira

1) Ntchito ya dongosolo

Musanayambe ntchito koyamba, ndikofunikira kuumitsa BOG yonse  njira yoyendera mpweya ndi njira yosungira mpweya mufiriji.

Pambuyo pa kugwira ntchito kwa nthawi yayitali kwa bokosi lozizira la liquefaction, mpweya wotsala wa carbon dioxide ndi chinyezi mu mpweya wa BOG woyeretsedwa zidzasonkhanitsidwa m'malo otentha kwambiri a bokosi lozizira la liquefaction, zomwe zimapangitsa kuti mphamvu zichuluke komanso kuti ligwiritsidwe ntchito kwambiri, komanso zingayambitse kuti bokosi lozizira la liquefaction lilephere kugwira ntchito bwino. Chifukwa chake, mu nthawi yogwira ntchito, bokosi lozizira la liquefaction lidzatenthedwa ndikusungunuka ndi nayitrogeni wotentha kapena mpweya wa BOG.

2) Kufotokozera njira

Mpweya wa BOG wochokera ku netiweki ya mapaipi a nayitrogeni umatenthedwa ndi magetsi kufika pa madigiri 60 mpaka 70. ℃ , kenako imalowa m'njira zoyendera kutsogolo ndi kumbuyo za mpweya wodyetsa ndi njira zoyendera kutsogolo ndi kumbuyo za firiji mu bokosi lozizira la liquefaction kuti litenthetse, kenako imatenthedwa kuchokera ku kutuluka kwa bokosi lozizira.

Rongteng imagwira ntchito yokonza zitsime za gasi, kuyeretsa gasi lachilengedwe, kubwezeretsa LPG, fakitale ya LNG ndi seti ya jenereta ya gasi lachilengedwe.
