High Quality China Small LNG Plant Factory - Natural gasi Liquefaction skid - Rongteng

Kufotokozera

Mpweya wachilengedwe wa Liquefaction, womwe posachedwapa umatchedwa LNG, ukusandutsa gasi wachilengedwe kukhala wamadzimadzi poziziritsa mpweya wachilengedwe womwe umakhala ndi mpweya wabwino kwambiri 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 maziko a kupanga 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 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.

Gasi wachilengedwe yemwe amalowa pamalopo amadutsa kaye pamagetsi owongolera ndi ma metering, omwe amazindikira kuwongolera ndi kuwerengera kwa gasi wobwera; Gasi wachilengedwe amalowa mu gawo loyeretsa gasi, pomwe mpweya wachilengedwe umatha kuchotsedwa CO2, kuchotsedwa kwa H2S ndikuchotsa madzi m'thupi. MDEA ndondomeko akulimbikitsidwa decarbonization ndi H2S kuchotsa, maselo sieve kutaya madzi m'thupi ndi nsanja atatu OR TEG ndondomeko kutaya madzi m'thupi akulimbikitsidwa kuti madzi m'thupi; Ndipo Ndi bwino kugwiritsa ntchito anachira ndi wothinikizidwa BOG kwa kusinthika mpweya;

Gasi woyeretsedwa mu gawo lopangira mafuta achilengedwe, refrigerant wosakanikirana (MRC liquefaction process) akulimbikitsidwa kuti azitulutsa mpweya wachilengedwe; LNG yamadzimadzi imasungidwa mu thanki yosungiramo, ndipo njira yosungiramo mumlengalenga ndi yotsika kutentha imalimbikitsidwa kuti isungidwe LNG. Tanki imodzi yosungiramo kutentha kwamlengalenga imakhala ndi BG compressor, ndipo BOG compressor imagwiritsidwa ntchito kukakamiza BOG musanalowe mu molecular sieve dryer Regeneration, kutengera pampu ya cryogenic kuti ikwaniritse kukhazikitsa.
