Khase ea tlhaho ea Liquefaction, eo haufinyane e bitsoang LNG, e fetola khase ea tlhaho hore e be mokelikeli ka ho pholisa khase ea tlhaho tlas'a khatello e tloaelehileng ho - 162 ℃. Liquefaction ea khase ea tlhaho e ka boloka haholo sebaka sa polokelo le lipalangoang, 'me e na le melemo ea boleng bo phahameng ba lik'halori, ts'ebetso e phahameng, e loketseng ho leka-lekana ha taolo ea mojaro oa litoropo, e loketseng ts'ireletso ea tikoloho, ho fokotsa tšilafalo ea litoropo joalo-joalo.

Liquefaction ke setsi sa tlhahiso ea LNG le semela sa LNG se kentsoeng ka skid. Hajoale, lits'ebetso tse holileng tsa ho qoelisoa ha khase ea tlhaho haholo-holo li kenyelletsa ts'ebetso ea "cascade liquefaction", ts'ebetso e tsoakiloeng ea sehatsetsing le ts'ebetso ea ho qhibiliha ka metsi.

Cascade khase ea tlhaho liquefaction process e sebelisa lintlha tse fapaneng tse belang tsa sehatsetsi tlas'a khatello e tloaelehileng ho fokotsa mocheso oa sehatsetsi mohato ka mohato ho fihlela sepheo sa ho qhibiliha ha khase ea tlhaho.

Mixed refrigerant cycle (MRC) ke ts'ebetso eo ho eona mefuta e fetang e mehlano ea lihatsetsi tse tsoakiloeng tse nang le likarolo tse ngata, joalo ka C1 ~ C5 Hydrocarbons le N2, e sebelisoang e le maro a sebetsang ho condense, mouoane le ho holisa mohato ka mohato ho fumana matla a sehatsetsi maemong a fapaneng a mocheso, ebe butle-butle ho pholile le ho qhibilisa khase ea tlhaho. Ts'ebetso e tsoakiloeng ea liquefaction ea refrigerant e arotsoe ka mefuta e mengata e fapaneng ea potoloho ea sehatsetsi.

Ts'ebetso ea liquefaction e nang le expander e bua ka mokhoa oa ho qhibiliha ha khase ea tlhaho ka ho sebelisa sehatsetsi se phahameng sa khatello ho hlokomela sehatsetsing sa Claude cycle sehatsetsing se nang le katoloso ea adiabatic ea turbo expander.

Lenaneo la ts'ebetso haholo-holo le kenyelletsa: yuniti ea taolo ea khatello ea khase ea phepelo le metering, yuniti ea tlhoekiso ea khase ea tlhaho le yuniti ea liquefaction ea khase ea tlhaho, sistimi ea polokelo ea sehatsetsing, sistimi e potolohang ea sehatsetsing, polokelo ea LNG le yuniti ea ho kenya.

Paramethara ea moralo

Ho qapa aLNG Plant Skid, re hloka parameter e latelang.

1) Maemo a mantlha a moralo oa semela:

Fepa phallo ea khase

Fepa khatello ea khase

Fepa mocheso oa khase

Metsi a mahala a khase ea phepelo

2) Sebopeho sa khase ea phepelo e felletseng (mole%)

3) Litlhaloso tsa sehlahisoa:

Liquefied natural gas:

Khatello ea ho tsoa

Subcooling mocheso tlas'a khatello ea outlet
