Liquefaction na iskar gas, wanda ake kira da ɗan gajeren lokaci LNG, yana tattara iskar gas zuwa ruwa ta hanyar sanyaya iskar gas ɗin ƙarƙashin matsi na al'ada zuwa - 162 ℃. Ruwan iskar iskar gas na iya adana sararin ajiya da sufuri, kuma yana da fa'idodi na babban darajar calorific, babban aiki, mai dacewa da daidaiton ka'idojin ɗaukar kaya na birni, mai dacewa da kariyar muhalli, rage gurɓataccen birni da sauransu.

Liquefaction shine jigon samar da LNG. A halin yanzu, manyan hanyoyin sarrafa iskar iskar gas sun haɗa da tsarin sarrafa ruwan sha, gaurayewar ruwan sha mai sanyi da kuma tsarin sarrafa ruwa tare da faɗaɗa.

Cascade na iskar gas na ruwa yana amfani da wuraren tafasa daban-daban na refrigerant a ƙarƙashin matsi na al'ada don rage yawan zafin jiki na firiji mataki-mataki don cimma manufar gurɓataccen iskar gas.

Cycle Catur (Mista) tsari ne wanda fiye da nau'i biyu na kayan maye, sannan a hankali yana fadada mataki-daban-daban, sannan sannu-sannu da gaske sanyi da gas na halitta. Ganyayyakin aikin shayarwar firji ya kasu zuwa nau'ikan sake zagayowar firji.

A liquefaction tsari tare da expander yana nufin aiwatar da iskar gas liquefaction ta amfani da babban matsa lamba refrigerant gane Reverse Claude sake zagayowar refrigeration tare da adiabatic fadada turbo expander.

Tsarin tsari ya ƙunshi: ciyar da matsi na iskar gas mai daidaitawa da na'ura mai aunawa, sashin tsabtace iskar gas da naúrar ruwan iskar gas, tsarin ajiya mai sanyi, tsarin matsawa refrigerant, ajiya na LNG da naúrar lodi.

Iskar iskar gas da ke shiga tashar ta farko ta wuce ta hanyar sarrafa matsa lamba da na'ura mai aunawa, wanda ke gane ka'idojin matsa lamba da ma'aunin iskar gas mai shigowa; Gas ɗin yana shiga sashin tsabtace iskar gas, inda iskar gas ɗin ke ƙarƙashin cirewar CO2, cirewar H2S da jiyya na bushewa. Ana ba da shawarar tsarin MDEA don lalatawa da cirewar H2S, tsarin cire ruwa na kwayoyin halitta tare da hasumiya uku KO TEG tsarin bushewa ana ba da shawarar don bushewa; Kuma ana ba da shawarar yin amfani da BOG da aka gano da kuma matsawa don sabunta iskar gas;

Tsaftataccen iskar gas a cikin sashin sarrafa iskar gas, gauraye refrigerant (Tsarin liquefaction MRC) ana ba da shawarar don ruwan iskar gas; LNG mai liquefied ana adana shi a cikin tankin ajiya, kuma ana ba da shawarar yanayin yanayi da tsarin ajiya mai ƙarancin zafi don ajiyar LNG. Ɗaya daga cikin tankin ajiya mai ƙarancin yanayi yana sanye da compressor BG, kuma ana amfani da kwampreso na BOG don matsawa BOG kafin shigar da busarwar kwayoyin halitta Regeneration, dangane da famfon cryogenic don cimma shigarwa.
