- this gas used as the motor flow of the ejector 8 is taken at the outlet of the last turbine (if several turbines are in series in the working circuit) and / or from the coldest outlet of the circuit (if several turbines 7 are arranged in parallel in the circuit).
- the pressure of this driving gas is for example between 5 and 10 bara, and preferably between 6 and 7 bara.
- the temperature of this motive gas can be for example between 28 and 35K and, preferably between 29.3 and 30K.
- the gas flow at the outlet of the ejector 8 depends on the performance of the ejector and on the characteristics of the suction flow and of the motor flow.
- a refrigerator using a refrigeration cycle conventionally subjects a cycle gas (working gas) to a thermodynamic cycle in which the temperature and pressure conditions are determined according to the positions in the cycle.
- the cycle fluid reaches at a so-called coldest end of the cycle a relatively lowest temperature in the cycle and at determined corresponding pressure conditions.
- the pressure of the ejector outlet gas stream is at least equal to the pressure of the low pressure working fluid stream of the cooling cycle at its coldest point (of the working circuit), in order to d '' be recycled (injected).
- This pressure can be for example between 1.25 bara and 2 bara, and preferably between 1.3 and 1.45 bara.
- the flow has a pressure greater than this pressure of the cycle gas at the coldest end of the cycle.
- the engine flow rate coming from the outlet of the turbine 7 which passes through the ejector 8 can be controlled as a function of the pressure conditions of the output flow of the ejector 8.
- the flow rate can in particular be adjusted from so that the pressure set point is constant and slightly higher than the pressure of the low pressure flow of the working fluid in the cooling cycle.
- the flow rate of the ejector or ejectors 8 depends on the number of tanks 13 (trailers) used and filled at the downstream end 22 of the cooled hydrogen circuit of the installation.
- the output stream of the ejector 8 must enter the cold box of the liquefier of the installation and be mixed with the low pressure stream of the working fluid of the liquefier cooling cycle. As illustrated, this output stream from the ejector 8 is preferably injected into the working circuit before the return of the working fluid to the compression member 6 (before passing through the exchangers 4, 3 providing heating up to the inlet of the low pressure compressor 6).
- the mixing (injection) is therefore preferably carried out at the cold end of the last exchanger 4 of the working circuit (above the thermosiphon exchanger if there is one and in the last exchanger 4 in series s' there is no thermosyphon). That is to say that the vaporization gas recovered in the tank 13 is mixed at this point of the working circuit with the possible vaporization gas coming from a fixed storage 16 (if any) and with the gas coming from from the outlet of a thermosyphon (if applicable).
- the vaporization gas supplied by mobile tanks 13 to be filled with liquid is intermittent because it is linked to the presence of filled trailers 13. Consequently, as illustrated, the ejector (s) 8 should preferably be able to be isolated from the liquefier 8 and from the loading pipes of the trailers 13 by means of a set of isolation valves 10, 12, 17. These valves should be closed when no vaporization gas is to be recovered.
- ejectors 8 can therefore be arranged and connected in parallel in the installation 1 with respective valves.
- the recommended number of ejectors 8 is preferably the maximum number of reservoirs 13 that can simultaneously generate vaporization gas at low pressure (which takes place when this or these reservoirs 13 receive liquid from storage 16 through the line 22.
- a truck can be accommodated in installation 1 without generating these low pressure gases: it may be in the process of being connected, or in the depressurization phase (by generating high pressure vaporization gases which do not require to use the ejector).
- two or four ejectors can be provided or any other number depending on the installation.
- valve sets For each ejector 8, the corresponding valve sets must be able to be put into the open or closed position independently, depending on the number of tanks 13 which generate vaporization gas at a given time.
- This solution makes it possible to recycle a large quantity of vaporization gas streams and to enhance their cold temperature. Compared to current solutions which use the hydrogen flow from circuit 2 to be cooled as the driving gas, this solution makes it possible to save the expansion of this hydrogen flow for a more advantageous use (expansion in a liquid turbine for example) .
- the invention also makes it possible to reduce the risk of sending impurities to storage 13, because the recovered vaporization gas will be purified again by joining the supply to the installation 1.
