High Quality China Mini LNG Plant Factory - 10~30 × 104Nm3/d Large LNG Liquefaction - Rongteng

Mawu Oyamba

Mpweya wachilengedwe wa Liquefaction, womwe umadziwika kuti LNG, ukusandutsa mpweya wachilengedwe kukhala wamadzimadzi poziziritsa mpweya wachilengedwe womwe umakhala ndi mpweya wabwino mpaka - 162 ℃. Kuphatikizika kwa gasi wachilengedwe kumatha kupulumutsa kwambiri malo osungira ndi oyendetsa, ndipo kumakhala ndi ubwino wamtengo wapatali wa calorific, ntchito yapamwamba, yogwirizana ndi kayendetsedwe ka katundu wa m'tawuni, kuthandizira kuteteza chilengedwe, kuchepetsa kuipitsidwa kwa mizinda ndi zina zotero.

Liquefaction ndiye pachimake pakupanga LNG komanso skid wokwera LNG chomera. Pakali pano, okhwima gasi liquefaction njira makamaka monga cascade liquefaction ndondomeko, osakaniza refrigerant liquefaction ndondomeko ndi liquefaction ndondomeko ndi expander.

Cascade gasi liquefaction ndondomeko amagwiritsa osiyana otentha mfundo refrigerant pansi kuthamanga yachibadwa kuchepetsa firiji kutentha sitepe ndi sitepe kukwaniritsa cholinga cha liquefaction gasi.

Mixed refrigerant cycle (MRC) ndi ndondomeko imene mitundu yoposa isanu ya mafiriji osakanikirana ndi zigawo zambiri, monga C1 ~ C5 Hydrocarbons ndi N2, amagwiritsidwa ntchito ngati madzi ogwirira ntchito kuti aphimbe, asungunuke ndi kukulitsa sitepe ndi sitepe kuti apeze mphamvu ya firiji pazigawo zosiyanasiyana za kutentha, kenako pang'onopang'ono kuziziritsa ndi kusungunula gasi wachilengedwe. Wosakaniza refrigerant liquefaction ndondomeko lagawidwa mitundu yosiyanasiyana ya refrigeration mkombero.

Njira yopangira liquefaction yokhala ndi expander imatanthawuza njira yowonongeka kwa gasi pogwiritsa ntchito firiji yothamanga kwambiri kuti izindikire reverse Claude cycle refrigeration ndi adiabatic kukula kwa turbo expander.

Ndondomekoyi imaphatikizapo: magetsi oyendetsa gasi ndi metering unit, gawo loyeretsera gasi ndi gasi wachilengedwe, makina osungiramo refrigerant, refrigerant circulating compression system, LNG yosungirako ndi katundu wonyamula.

Design parameter

Kupanga aLNG Plant Skid, tikufuna zotsatirazi.

1) Zinthu zoyambira pamapangidwe a mbewu:

Kudyetsa gasi kuyenda

Dyetsani kuthamanga kwa gasi

Dyetsani kutentha kwa gasi

Madzi aulere a gasi wamafuta

2) Zambiri zamafuta amafuta (mole%)

3) Product specifications:

Gasi wachilengedwe wosungunuka:

Outlet pressure

Kutentha kwa subcooling pansi pa kukakamiza kotuluka

Kuchuluka kwa nayitrogeni

Kuchuluka kwa carbon dioxide
