Installation and process for production of a cryogenic fluid

An installation for production of a cryogenic fluid, wherein the cryogenic fluid comprises liquefied hydrogen, the installation comprising:

• a hydrogen circuit configured to cool hydrogen gas having an upstream end that is configured to connect to a source of hydrogen gas, and a downstream end which is configured to connect to at least one receiver system;
• a set of heat exchangers positioned, in at least one cold box, in thermal exchange with the hydrogen circuit;
• a pre-cooling device configured to pre-cool the hydrogen circuit to a first determined temperature, wherein the pre-cooling device is in thermal exchange with a first part of the set of heat exchangers;
• and
• a cryogenic cooling device in thermal exchange with a second part of the set of heat exchangers, wherein the cryogenic cooling device is configured to cool the hydrogen circuit to a second determined temperature that is lower than the first temperature,
• wherein the pre-cooling device comprises a pre-cooling fluid closed-circuit refrigerator,
• wherein the pre-cooling fluid closed-circuit refrigerator further comprises:
• a device compressor configured to compress the pre-cooling fluid,
• an expansion turbine configured to expand the pre-cooling fluid,
• wherein said pre-cooling fluid closed-circuit refrigerator further comprises one or a plurality of passages configured for thermal exchange with at least one heat exchanger of the first part of the set of heat exchangers,
• wherein the cryogenic cooling device comprises a refrigerator with a cycle for refrigeration of a cycle gas in a work circuit, the cycle gas comprising at least one from out of:
• hydrogen, helium, and neon,
• wherein the work circuit of the refrigerator comprises:
• a cycle gas compressor configured to compress the cycle gas,
• a cooling heat exchanger configured to cool the compressed cycle gas,
• an cycle gas expansion turbine configured to expand the compressed and cooled cycle gas, and
• a heating heat exchanger configured to heat the expanded cycle gas,
• wherein the cooling heat exchanger and/or the heating heat exchanger comprise(s) at least one first cycle heat exchangers distinct from the first part of the pre-cooling heat exchangers of the circuit, wherein the first cycle heat exchangers are configured to be cooled by thermal exchange with the pre-cooling fluid circuit of the pre-cooling device,
• wherein the pre-cooling device further comprises:
• a first thermosiphon having a first input and a first output connected to a first loop of the pre-cooling fluid circuit, the first loop being in thermal exchange with at least one heat exchanger of the first part of the set of heat exchangers;
• and
• a second thermosiphon, distinct from the first thermosiphon, having a second input and a second output connected to a second loop of the pre-cooling fluid circuit, the second loop being in thermal exchange with the at least one first cycle heat exchanger,
• wherein the first thermosiphon and the second thermosiphon are positioned in parallel within the pre-cooling fluid circuit.
