Abstract (en)
[origin: WO2022106260A1] A method for producing LNG (12) from natural gas (14), comprising the following steps: - liquefying at a least first portion (19) of the natural gas (14) in a first heat exchanger (18) by heat exchange with a mixed first refrigerant (44) in a closed cycle (42), - subcooling the liquefied natural gas (22) in a second heat exchanger (20) by heat exchange with a second refrigerant (62) of a second refrigerant cycle (60), - expanding the stream of subcooled liquefied natural gas (26) and entering into a flash gas separator (32), - withdrawing liquefied natural gas at the bottom of the separator, and withdrawing, at the top, a gas flow (34), and supplying the second refrigerant cycle (60) with at least one portion of said gas flow.
