10~30 ×10⁴Nm³/d Kuchuluka kwa LNG Liquefaction

Chiyambi

Mpweya wachilengedwe wothira madzi, womwe umatchedwa LNG posachedwa, umasungunula mpweya wachilengedwe kukhala madzi mwa kuziziritsa mpweya wachilengedwe wothira madzi pansi pa mphamvu yachibadwa kufika pa -162 ℃. Mpweya wachilengedwe wothira madzi umatha kusunga malo osungiramo zinthu ndi mayendedwe, ndipo uli ndi ubwino wa kukhala ndi mphamvu zambiri, kugwira ntchito bwino, kulimbikitsa malamulo a katundu m'mizinda, kulimbikitsa kuteteza chilengedwe, kuchepetsa kuipitsa kwa mizinda ndi zina zotero.

Kutulutsa madzi ndiye maziko a kupanga LNG ndi fakitale ya LNG yokwezedwa pa skid. Pakadali pano, njira zopumira zamadzimadzi za gasi wachilengedwe zimaphatikizapo njira yotulutsira madzi, njira yosakaniza yotulutsira madzi mufiriji komanso njira yotulutsira madzi ndi expander.

Njira yothira madzi a gasi lachilengedwe pogwiritsa ntchito mpweya wachilengedwe imagwiritsa ntchito malo osiyanasiyana owira a refrigerant pansi pa mphamvu yachibadwa kuti ichepetse kutentha kwa firiji pang'onopang'ono kuti ikwaniritse cholinga cha kuthira madzi a gasi lachilengedwe.

Mzunguliro wosakaniza wa refrigerant (MRC) ndi njira yomwe mitundu yoposa isanu ya mafiriji osakaniza amitundu yosiyanasiyana, monga C1 ~ C5 Hydrocarbons ndi N2, amagwiritsidwa ntchito ngati madzi ogwirira ntchito kuti asungunuke, asungunuke ndikukula pang'onopang'ono kuti apeze mphamvu yoziziritsira pamlingo wosiyanasiyana wa kutentha, kenako pang'onopang'ono kuziziritsa ndi kusungunula mpweya wachilengedwe. Njira yosakaniza ya refrigerant liquefaction imagawidwa m'mitundu yosiyanasiyana ya mafiriji.

Njira yothira madzi pogwiritsa ntchito expander imatanthauza njira yothira madzi pogwiritsa ntchito refrigerant yamphamvu kwambiri kuti ipange reverse Claude cycle refrigerant ndi adiabatic expander expander.

Ndondomeko ya ndondomekoyi ikuphatikizapo: chipangizo chowongolera kuthamanga kwa mpweya wa chakudya, chipangizo choyeretsera mpweya wachilengedwe ndi chipangizo choyeretsera mpweya wachilengedwe, chipangizo chosungiramo zinthu zoziziritsa kukhosi, chipangizo chochepetsera mpweya wa m'firiji, chipangizo chosungiramo zinthu zoziziritsa kukhosi ndi chipangizo chokweza mpweya wa LNG.

Gawo la kapangidwe

Kuti tipange LNG Plant Skid, tikufunika njira yotsatirayi.

1) Mikhalidwe yoyambira ya kapangidwe ka chomera:

Kuyenda kwa mpweya wodyetsa

Kupanikizika kwa mpweya wodyetsa

Kutentha kwa mpweya wodyetsa

Mpweya wopatsa chakudya wopanda madzi

2） Kuphatikizika kwa mpweya wothira mwatsatanetsatane (mole%)

3) Mafotokozedwe a Zamalonda:

Mpweya wachilengedwe wosungunuka:

Kupanikizika kwa malo otulutsira

Kutentha kwa subcooling pansi pa kukakamizidwa kwa soketi

Kuchuluka kwa nayitrogeni

Kuchuluka kwa mpweya woipa m'thupi
