Kufotokozera kwamtundu uliwonse wa BOG reliquefying plant

BOG ya tanki yosungiramo LNG imalowa m'bokosi lozizira la liquefaction pambuyo pa kukakamizidwa ndi metering, itakhazikika, kusungunuka, ndi kutenthedwa bwino mu mbale-fin heat exchanger, ndikubwerera ku tanki yosungiramo LNG monga LNG mankhwala pambuyo pogwedeza.

Njira yayikulu yaukadaulo ya chipangizochi ndi:

MRC (mixed refrigerant) ndondomeko ya firiji yozungulira imagwiritsidwa ntchito kukhetsa mpweya wonse wa BOG woyeretsedwa;

Ndondomekoyi ikuphatikiza:

Kudyetsa gasi kusefera kulekana ndi pressurization unit;

LNG liquefaction dongosolo;

Chigawo cha refrigerant chosakanizidwa;

1) Kudyetsa gasi kupatukana ndi pressurization unit

1) Kufotokozera ndondomeko

BOG mpweya amalowa mpweya mkangano gasifier ndi chakudya mpweya kutentha exchanger, ndipo pambuyo psinjika, kulekana, ndi metering, akulowa kunsi mtsinje liquefaction dongosolo.

Zida zazikuluzikulu zogwirira ntchito ndi mpweya wotenthetsera mpweya, chowotcha kutentha kwa gasi, mita yothamanga, gawo lowonjezera la compressor, ndi zina zambiri.

2)Liquefaction unit

1) Kufotokozera ndondomeko

Musanalowe mu gawo la liquefaction, mpweya woyeretsa uyenera kuwunikiridwa kuti muwonetsetse kuti zomwe zili m'madzi, zonunkhira zonse ndi mercury zimakwaniritsa zofunikira kuti mulowemo.liquefaction unit.

Oyeretsedwa BOG mpweya umayamba kulowa mu liquefaction kutentha exchanger mu bokosi ozizira, pang'onopang'ono utakhazikika ndi kubwerera otsika kutentha osakaniza refrigerant, ndiyeno supercooled kuti -162°C, kenako lowetsani cholekanitsa cha LNG kuti mupeze zinthu za LNG.

Zida zazikulu ndi bokosi lozizira, lomwe makamaka limaphatikizapo osinthanitsa kutentha kwa mbale, olekanitsa osiyanasiyana, ndi zina zotero.

3) Kuphatikizika kwa refrigerant ndi gawo lofananira

1) Kufotokozera ndondomeko

Refrigerant yosakanikirana ya chipangizochi idzapangidwa ndi methane yoyeretsedwa, nitrogen ndi hydrocarbon refrigerants.

Kuponderezedwa kwa refrigerant kumakhala ndi chopondera cha refrigerant chotentha komanso chozizira chozizira. Kutentha kotentha kwa refrigerant compressor makamaka kumapereka mphamvu yoziziritsira kumapeto kwa kutentha kwapamwamba, ndipo mpweya wozizira wa refrigerant compressor makamaka umapereka mphamvu yoziziritsa ya gawo lotsika.

Zida zazikulu ndi refrigerant cycle kompresa, refrigerant proportioning tank, etc.

2) Mapangidwe a magawo

Mphamvu yamadzimadzi: 224.7 matani / d

Mtundu wa Compressor: Screw Compressor

2 kompresa (1 mkulu ndi otsika kutentha refrigerant kompresa aliyense)

Kuthamanga kwa 0.3MPa.G

Kutentha kwa mpweya 40.0℃

Kuthamanga kwa mpweya 1.9MPa.G (kutanthauza kutulutsa kozizira komaliza)

Kutentha kwa mpweya 40°C(ponena za kutulutsa kozizira komaliza)

3) Zosintha zosiyanasiyana

50% ~ 110%.

4) Cold box kutentha unit

1) System ntchito

Musanayambe kwa nthawi yoyamba, m'pofunika kuyanika BOG yonse gasi otaya njira ndi refrigerant refrigeration otaya njira chipangizo.

Pambuyo pa nthawi yaitali ntchito ya liquefaction ozizira bokosi, yotsalira mpweya woipa ndi chinyezi mu oyeretsedwa BOG mpweya adzaunjikana mu otsika-kutentha mbali ya liquefaction ozizira bokosi , kuchititsa kuwonjezeka kukana ndi kumwa mphamvu, komanso kungayambitse liquefaction ozizira bokosi kulephera kugwira ntchito bwino. Chifukwa chake, pakatha ntchito, bokosi lozizira la liquefaction limatenthedwa ndikusungunuka ndi nayitrogeni kapena mpweya wa BOG.

2) Kufotokozera ndondomeko

Mpweya wa BOG wochokera ku netiweki wapaipi ya nayitrogeni umatenthedwa ndi magetsi mpaka 60-70℃ , ndiyeno amalowa kutsogolo ndi kumbuyo otaya ngalande za chakudya mpweya ndi kutsogolo ndi n'zosiyana otaya ngalande za refrigerant mu liquefaction ozizira bokosi kwa Kutentha, ndiyeno ndi usavutike mtima kuchokera ozizira bokosi kumaliseche.

Rongteng amagwira ntchito pazamankhwala amtundu wa gasi, kuyeretsa gasi, kuchira kwa LPG, chomera cha LNG ndijenereta ya gasi wachilengedwe.
