Dual mixed refrigerant natural gas liquefaction with staged compression
Patent
·
OSTI ID:6502396
An apparatus and process for liquefying natural gas using two closed-cycle, multicomponent refrigerants; a low level refrigerant which cools the natural gas and a high level refrigerant which cools the low level refrigerant wherein the improvement comprises phase separating the high level refrigerant after compression and fully liquefying the vapor phase stream against external cooling fluid after additional compression.
