Okwu mmalite

Mmiri mmiri mmiri, nke a na-akpọ LNG n'oge na-adịghị anya, na-eme ka gas dị n'ime ya ghọọ mmiri mmiri site na ime ka ikuku gas dị jụụ n'okpuru nrụgide nkịtị ruo -162 ℃. Ngwunye ikuku gas nwere ike ịchekwa ohere nchekwa na njem njem, ma nwee uru nke nnukwu uru calorific, arụmọrụ dị elu, na-eme ka nguzozi nke iwu ibu obodo, na-eme ka nchebe gburugburu ebe obibi, na-ebelata mmetọ obodo na ihe ndị ọzọ.

Liquefaction bụ isi nke mmepụta LNG na osisi skid na-agbanye LNG. Ka ọ dị ugbu a, usoro mmịnye gas nke tozuru okè na-agụnye usoro mmiri mmiri cascade, usoro mmịpụta refrigerant agwakọta yana usoro mmịpụta na expander.

Cascade eke gas liquefaction Usoro na-eji dị iche iche esi esi nke refrigerant n'okpuru nkịtị mgbali iji belata refrigeration okpomọkụ nzọụkwụ site nzọụkwụ iji nweta nzube nke eke gas liquefaction.

Mixed refrigerant cycle (MRC) bụ usoro nke a na-eji ihe karịrị ụdị ise nke multi-component agwakọta refrigerants, dị ka C1 ~ C5 Hydrocarbons na N2, ka mmiri na-arụ ọrụ condense, evaporate na ịgbasa nzọụkwụ site nzọụkwụ iji nweta refrigeration ike dị iche iche okpomọkụ ọkwa, wee jiri nwayọọ nwayọọ na-ajụkwa na liquefy eke gas. Ngwakọta ngwakọta refrigerant liquefaction usoro na-ekewa n'ime ọtụtụ ụdị dị iche iche nke refrigeration okirikiri.

The liquefaction usoro na expander na-ezo aka usoro nke eke gas liquefaction site na iji elu mgbali refrigerant na-aghọta reverse Claude okirikiri refrigeration na adiabatic mgbasawanye nke turbo expander.

Atụmatụ usoro a gụnyere: nri gas nrụgide na-achịkwa na metering unit, eke gas ọcha unit na eke gas liquefaction unit, refrigerant nchekwa usoro, refrigerant ikesa usoro mkpakọ, LNG nchekwa na loading unit.
