Abstract (en)
[origin: WO2022253847A1] The device (100) for pre-cooling a stream (101) of a target gas to a temperature less than or equal to 90 K has: - a group (105) of at least two heat exchangers (106, 107, 108, 136) for exchanging heat between the stream of target gas, a stream (102) of a first cooling fluid and at least one stream chosen from a stream of a second cooling fluid and a stream of a third cooling fluid, - a closed circuit (110) for circulation of a stream of a second cooling fluid, said fluid comprising at least methane, said circuit having: - at least one compression stage (111, 112), - at least one liquid-gas separation stage (115, 116), and - at least one expansion stage (120, 121, 122), and - a circuit (125) for circulation of a stream of the third cooling fluid through at least one of the heat exchangers.
