- thermosiphon 48A of the pre-cooling fluid has at least one inlet and one outlet connected to a loop of the pre-cooling fluid circuit 18 in heat exchange with at least one first cycle heat exchanger 15, 16.
- the first heat exchanger(s) 15, 16 of the cycle comprise at least one heat exchanger in thermal exchange with a flow of pre-cooling fluid of the circuit 18 leaving a thermosiphon 48A.
- thermosiphon 48A connected to at least one exchanger 16 makes it possible to effectively regulate the temperature of the cycle fluid of the refrigerator 9.
- the pre-cooling liquid is produced by the pre-cooling device 8.
- the liquid pre-cooling fluid can be expanded in a turbine 38 or a valve before being sent to the thermosiphons 48, 48A.
- the pressures within the thermosiphons 48, 48A can be different.
- the low-pressure pre-cooling fluids produced by the thermosiphons 48, 48A and by the expansion device 38 can be put into heat exchange with all or part of the heat exchangers (pre-cooling heat exchangers 5, 6 of the circuit 2 on the one hand and the heat exchangers 15, 16 of the refrigerator circuit 9 on the other hand).
- This or these relatively cold cooling fluid flows release(s) frigories respectively to the exchangers concerned to cool the gas 2 to be cooled and the cycle gas.
- the refrigerant thus heated is returned to the inlet of the same compressor(s) 28 of the pre-cooling device 8 and a new cycle can begin.
- thermosyphon 48A for the pre-cooling of the cycle gas of the refrigerator 9 makes it possible to pre-cool the cycle gas of the refrigerator 9 to a lower temperature. This makes it possible to reduce the energy consumption for the liquefaction of the gas to be cooled from the circuit 2 in the cold box 4.
- the temperature can be lower because the temperature of the liquid pre-cooling fluid is controlled by the pressure within the thermosyphons 48, 48A.
- the heat exchange can be greater in the dedicated exchangers 6, 16.
- thermosiphon 48 and/or 48A operates at a pressure between 1.5 and 3.5 bara and at a corresponding temperature between 80.8K and 89.6K.
- thermosiphon 48A operates at a lower pressure than the thermosiphon 48.
- a valve upstream of at least one thermosiphon 48, 48A allows the pressures to be adjusted independently.
- the heat exchanger(s) 5, 6 configured for pre-cooling the circuit 2 of gas to be cooled, and only a part 38, 48 of the pre-cooling device (8) (cold elements: turbine(s), thermosiphon, cold pipes, cold valve(s), etc.) are arranged in the same first cold pre-cooling box 3.
- This first cold box 3 is preferably thermally insulated under vacuum and/or thermally insulated via perlite (or other insulation) and swept with a gas such as nitrogen for example.
- the first cycle heat exchanger(s) 15, 16, the second thermosiphon 48A and only a part 38 of the pre-cooling device 8 are arranged in a second cold pre-cooling box 3A.
- This second cold box 3A is preferably thermally insulated under vacuum or thermally insulated via perlite (or other insulation) and swept with a gas such as nitrogen for example.
- the second cycle heat exchanger(s) 7 which are provided for liquefying the gas of the gas circuit 2 to be cooled are preferably located in a third cold box 4 separate from the first cold box 3 and the second cold box 3A (thermally insulated under vacuum or otherwise).
- This third cold box 4 also preferably contains the associated cryogenic components (turbine, valve(s)).
- the last second cycle heat exchanger 7 is in heat exchange with a first portion of the working circuit 19 of the device 9 conveying cycle gas before passage through an expansion member 39 (turbine(s) 39) and with a second portion of the working circuit 19 of the device 9 conveying cycle gas after passage through said expansion member 39. That is to say that the cycle exchanger 7 can comprise multiple passages of the working circuit 19 of the refrigerator 9.
- the installation preferably comprises means for purifying the cooled hydrogen, these means being located in the second cold box 3A. These means serve to remove the water and/or carbon dioxide and/or nitrogen contained in the cooled hydrogen.
- the hydrogen cools in the first cold box 3 and then goes to the second cold box 3A to be purified by the purification means P.
- the purified hydrogen is then cooled again in a heat exchanger of the first box.
- the first cold box 3 may contain at least one catalyst in the first cold box, the hydrogen purified in the second cold box 3A being sent to the catalyst of the first cold box.
- the first cold box 3 preferably does not contain means for purifying hydrogen.
- the first cold box 3 can have standardized dimensions while the second cold box 3A contains all the equipment whose dimensions change according to the composition of the feed flow to be liquefied.
- the installation may only include cold boxes 3, 3A, with cold box 4 being added at a later stage in the manufacture of the installation.
- the hydrogen flow 21 containing impurities likely to liquefy or even solidify in the cold box 4 must be purified downstream of the cold box 4.
- hydrogen 21 is cooled in exchanger 5 in cold box 3 and then sent to cold box 3A to be purified in adsorption purification unit P, the purified flow then returning to cold box 3 for a catalysis step in catalyst C1, followed by cooling in exchanger 6, again a catalysis step in catalyst C2 and cooling in exchanger 6 before leaving cold box 3 as flow 22 to join cold box 4 for final cooling.
- Catalysis is used for the ortho-para conversion of hydrogen, in a conventional manner. .
- Purification unit P can only accept a fairly pure gas feed, because a high impurity level leads to larger catalysts, increasing the dimensions of the module. Placing the P purification in the cold box 3A will be a preferred solution when the gas load 21 requires a lot of purification and therefore adsorbent beds of a significant size.
- the cold box 3A also contains the thermosiphon 48A whose liquid 50 is heated in the exchanger 16 and returned to the thermosiphon 48A.
- a gas 32 coming from the thermosiphon is heated in the exchanger 15 with the gas 19 by heat exchange with the gas 30 which cools before being sent to the exchanger 16.
- the purification unit P is located in the cold box 3, the cold box 3A mainly containing the thermosiphon 48A and the exchangers 15, 16.
- the invention allows the flexibility of having a less pure charge 21 and coming from any source, for example an ATR or SMR type reformer, an electrolyser, a pipeline, a hydrogen deposit, etc.
