Babban ingancin China Ƙananan Sikelin Liquefied Natural Gas Exporters - 10~30 ×104Nm3/d Manyan LNG Liquefaction - Rongteng

Gabatarwa

Liquefaction na iskar gas, ba da jimawa ba ana kiransa 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 tushen samar da LNG da shukar LNG mai skid. 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.
