摘要： Method for hydrogen liquefaction comprising at least one precooling step, wherein a hydrogen feed flow is cooled by a first refrigerant, a cooling step, wherein the hydrogen feed flow is cooled by a second refrigerant, and a step of expanding the hydrogen feed flow. Each of the first and second refrigerants is successively subjected to at least one compression and to at least one expansion in order to cool it, and a liquid phase of the first refrigerant cools the second refrigerant between at least three stages of said compression so that the second refrigerant does not exceed a temperature of 150 K, optionally 113 K, during said compression of the second refrigerant.

摘要： The device (100) for cooling a flow (101) of a target fluid predominantly comprising dihydrogen, comprises:
a first heat exchanger (105) configured to cool an intermediate refrigerant fluid (110) by heat exchange with an expanded dioxygen flow (115),
an intermediate closed circuit (120) for transporting the intermediate refrigerant fluid from the first heat exchanger to a second heat exchanger (125),
a means (130) for compressing the intermediate refrigerant fluid along the intermediate closed circuit,
the intermediate refrigerant fluid, configured to remain in the liquid or supercritical state at least upon passing through the compression means and
the second heat exchanger configured to cool the target fluid flow by heat exchange with the intermediate refrigerant fluid cooled in the first heat exchanger.-

摘要： The device (100) for pre-cooling a flow (101) of a target gas to a temperature of less than or equal to 90 K comprises:
a group (105) of at least two heat exchangers (106, 107, 108, 136) for exchanging heat between the target gas flow, a flow (102) of a first cooling fluid and at least one flow among a flow of a second cooling fluid and a flow of a third cooling fluid,
closed circulation circuit (110) for a flow of a second cooling fluid, said fluid comprising at least methane, said circuit comprising:
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 circulation circuit (125) for a flow of the third cooling fluid through at least one of said heat exchangers.-

摘要： The device (100) for pre-cooling a flow of a gas comprises:
a separator (135) of a coolant flow (125), downstream from a compressor (155), into two flows:
one coolant flow (140) referred to as “medium-pressure”; and
one coolant flow (145) referred to as “low-pressure”;
a first exchanger (105) exchanging heat between the flow (120) of the gas to be pre-cooled and at least the medium-pressure coolant flow (140) comprising at least nitrogen;
an expander (150) of the low-pressure coolant flow;
a second exchanger (110) exchanging heat between the flow of a gas and the expanded low-pressure coolant flow on output from the second expander; and
a third exchanger (115) exchanging heat between the flow of a gas and the low-pressure coolant flow on output from the second heat exchanger.
