Mawu Oyamba
Mpweya wachilengedwe wa Liquefaction, womwe umadziwika kuti LNG, ukusandutsa gasi wachilengedwe kukhala wamadzimadzi poziziritsa mpweya wachilengedwe womwe uli 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 chomera chokwera cha LNG. 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 njira imene mitundu yoposa isanu ya mafiriji osakanikirana ndi zigawo zambiri, monga C1 ~ C5 Hydrocarbons ndi N2, amagwiritsidwa ntchito ngati madzi ogwirira ntchito kuti apangike, asungunuke ndi kukulitsa pang'onopang'ono kuti apeze mphamvu ya firiji. osiyanasiyana kutentha, ndiyeno pang'onopang'ono kuziziritsa ndi liquefy gasi. Wosakaniza refrigerant liquefaction ndondomeko lagawidwa mitundu yosiyanasiyana ya refrigeration mkombero.
Njira yopangira liquefaction yokhala ndi expander imatanthawuza njira yowonongeka kwa gasi pogwiritsa ntchito refrigerant yothamanga kwambiri kuti izindikire reverse Claude cycle refrigeration ndi adiabatic expansion of 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
Kuti mupange LNG Plant Skid, tifunika 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
