    [0001] The present invention relates to a station for supplying a flammable fuel fluid and a method of storage. The invention relates more particularly to a station for supplying a flammable fuel fluid, the station comprising a first cryogenic tank for storing flammable fuel in the form of a cryogenic liquid, a second cryogenic storage tank for an inert gas stored in the form of a cryogenic liquid, a cooling circuit in heat exchange with the first tank, the cooling circuit comprising an upstream end connected to the second cryogenic tank for withdrawing cryogenic fluid in the second cryogenic tank in order to transfer the frigories of the fluid from the second cryogenic reservoir to the first reservoir, the station comprising a fluid withdrawal circuit of the second reservoir. The storage of a cryogenic liquid in a vacuum insulated tank is subject to a rise in its internal pressure. Indeed, in the absence of regular liquid withdrawal, the heat inputs by the tank supports, pipes and insulation warm the inter-wall void. Liquid vaporizes in the tank and therefore the pressure will increase until a safety valve is opened. The degassing of gases such as nitrogen, oxygen and argon is not too problematic however, when the stored gas is flammable (natural gas, hydrogen ...) such degassing may create an explosive cloud therefore an "ATEX zone". A known solution is to condense part of the gas phase in the tank or to cool the liquid to prevent its vaporization (see DE19903214). This solution, however, does not allow precise control of the pressure or temperature in the fuel tank. An object of the present invention is to overcome all or part of the disadvantages of the prior art noted above. To this end, the station according to the invention, moreover in accordance with the generic definition given in the preamble above, is essentially characterized in that the cooling circuit comprises two pipes comprising an upstream end connected to the second reservoir. , the two pipes being each provided with a respective exchanger housed in the first reservoir, the two exchangers being located respectively in the upper and lower part of the first reservoir. Furthermore, embodiments of the invention may include one or more of the following features: the fluid withdrawal circuit of the second reservoir is fluidly connected to the cooling circuit and supplied with fluid from the latter; first and second tanks are double-walled cryogenic tanks with inter-wall void, the first and second tanks are housed in a common external vacuum envelope, the second tank is placed above the first tank, the first tank; contains a fuel among: natural gas, hydrogen, - the second tank contains one of: nitrogen, argon, - the draw-off circuit comprises a chimney provided with a valve forming a vent in determined overpressure within said circuit, the station comprises at least one fuel leakage detector of the first reservoir and at least one controlled component for opening a tion of the draw-off circuit, the at least one opening member being automatically controlled in response to a leak detection by the at least one detector for releasing fluid from the second cryogenic tank so as to inert a volume within the station, the leak detector comprises at least one of: a fuel sensor, a catalytic probe, a chemical sensor, an optical type sensor, the at least one opening member comprises at least one of: a valve, a valve, a spray nozzle. the at least one opening member is spaced from the first reservoir by a distance of between zero meters and five meters and preferably between zero and two meters; the station contains a control cabinet comprising functional control members of the station, the at least one opening member having an end which opens at least partially in said cabinet, the station comprises two spaced apart separate opening members, the station comprises two opening members located respectively on two distinct portions of the extraction circuit connected respectively to the two separate pipes of the cooling circuit provided with the exchangers. The invention also relates to a method of storing a flammable fuel fluid in a filling station comprising a first cryogenic tank storing flammable fuel in the form of a cryogenic liquid, a second cryogenic tank storing an inert gas at a lower temperature at the temperature of the fluid contained in the first reservoir, the station comprising a cooling circuit in heat exchange with the first reservoir, the cooling circuit comprising an upstream end connected to the second cryogenic reservoir, the process comprising a cryogenic fluid withdrawal step of the second cryogenic tank, a step of heat exchange between the withdrawn fluid and the fluid contained in the second cryogenic tank to reduce or eliminate the vaporization of the fluid in the first tank, the method comprising a pressure control step and / or da temperature ns the first tank by distributing the fluid drawn into the second tank in exchangers disposed respectively in the upper and lower parts of the first tank. According to other possible particularities: the fluids withdrawn from the second reservoir and distributed in the two exchangers located at the top and bottom are distinct, that is to say that the fluid flowing in one of the two exchangers comes directly from the second tank without first going into the other exchanger. The invention may also relate to any alternative device or method comprising any combination of the above or below features.
    [0002] Other features and advantages will appear on reading the following description, with reference to the figures in which: - Figure 1 shows a sectional view, schematic and partial illustrating a first embodiment of a supply station of fuel according to the invention, - Figure 2 shows a sectional view, schematic and partial, illustrating a second embodiment of a fuel supply station according to the invention. The station 1 illustrated in FIG. 1 is a station for supplying a flammable fuel fluid, for example natural gas, from a first cryogenic tank 2 storing the flammable fuel in the form of a cryogenic liquid (for example -140 ° C). More precisely, the first reservoir 2 contains a diphasic liquid / gas mixture. Station 1 comprises a second cryogenic tank 3 for storing a non-flammable gas and in particular an inert gas such as nitrogen stored at a temperature of -196 ° C.
    [0003] The inert gas is also stored as a cryogenic liquid (two-phase liquid / gas mixture). The first 2 and second 3 tanks are preferably double-walled cryogenic tanks with inter-wall void. The station 1 comprises a fluid withdrawal circuit 15 for the first tank 3. This circuit 15 comprises, for example, a pipe for supplying liquid fuel to a user, for example to fill tanks or tanks of vehicles. Alternatively or in combination, the withdrawn liquid can be supplied to a vaporization unit to supply a user with gas. The station 1 comprises a cooling circuit 4 in heat exchange with the first tank 2 and in particular with the fluid inside the first tank 2. The cooling circuit 4 comprises two pipes having an upstream end connected to the second cryogenic tank 3 for withdrawing cryogenic fluid in the second cryogenic tank 3. In the illustrated example the two lines 4, 14 have upstream ends (connected to the second tank 3) separate. Of course, it is possible to envisage a common for connection to the second tank 3. The two lines 4, 14 of the cooling circuit 4 each comprise, downstream, a portion 9, 10 in heat exchange with the interior of the first reservoir 1 for the purpose of transferring frigories of the fluid from the second cryogenic reservoir 3 to the first reservoir 2. These heat exchange portions 9 comprise, for example, a coil, a condenser or any type of suitable exchanger.
    [0004] In addition, the two exchangers 9, 10 housed inside the first tank 2 are respectively located in the upper and lower part of the first tank 2 for cooling respectively the gaseous and liquid parts of the fuel. This arrangement distributes the cooling fluid from the second reservoir 3 into the first 9 and / or the second exchanger 10 to selectively cool the gas portion and / or the liquid portion of the first reservoir fluid 2. Pressure control and cooling of this fuel fluid is thus improved. Downstream of each heat exchanger 9, 10, each cooling pipe 4, 14 may comprise a pipe 7 for supplying cooling fluid to a user (in gaseous and / or liquid form). Thus, the downstream portion 7 of the cooling circuit can form a fluid withdrawal circuit of the second reservoir 3. That is to say that the withdrawal circuit 7 is connected to the cooling circuit 4 and supplied with inert fluid from this last.
    [0005] This withdrawal circuit 7 may comprise a chimney 16 provided with a valve forming a vent in case of determined overpressure. FIG. 2 illustrates a possible variant embodiment of the invention that differs from that of FIG. 1 only in that the station comprises a leak detection and fire protection system.
    [0006] The elements identical to those described above are designated by the same reference numerals and are not described a second time. Thus, in the embodiment of FIG. 2, the station 1 comprises a fuel leak detector 5 of the first tank 2. The leak detector 5 comprises for example at least one of: a fuel sensor (in particular a natural gas sensor), a catalytic probe, a chemical sensor, an optical type sensor, or any other suitable system. In addition, the station comprises two bodies 6, 11 controlled opening a portion of the circuit 4, 7 cooling / racking. The two members 6, 11 of distinct openings are preferably spaced and fed respectively by the two lines 4, 14. The two opening members 6 are automatically controlled in response to leak detection by the detector 5 to release fluid from the second cryogenic tank 3 so as to inert a volume within the station. The opening members 6, 11 may comprise at least one of: a valve, a valve, a spray nozzle or any other suitable device for releasing inert gas in a given zone in response to a leak detection of fuel.
    [0007] For example, at least one of the opening members 6, 11 is spaced from the first reservoir 2 by a distance of between zero meters and five meters and preferably between zero and two meters, to inert the zone directly adjacent to the first reservoir. 2. Alternatively, one of the opening members 6, 11 is located at a distance, to inerter an area further away, for example between two and ten meters if the leak is likely to occur there and constitutes a zone to risk. The two opening members 6, 11 can thus open in separate or common areas of the station. In the case where the station comprises a control cabinet 8 grouping functional control members of the station (valves, control electronics, displays ...) at least one of the opening members 6, 11 may comprise one end which opens at least partially into said cabinet 8 to protect it from a fire. As illustrated in the figures and without this being limiting, advantageously but not imperatively, the envelopes delimiting the storage volumes of the first 2 and second 3 tanks can be housed in a common outer envelope 12 under vacuum. That is, the first 2 and second 3 vacuum insulated tanks containing respective fluids at different temperatures share the same outer shell and the same inter-wall void.
    [0008] Of course, the invention is not limited to the above examples, for example, the station may have only one or three or more opening members.
    [0009] It is therefore easy to understand that while being of simple and inexpensive structure, the station 1 makes it possible to effectively use the cooling fluid of the fuel tank to secure the station in the event of fuel leakage. The station can be stationary or mobile (mounted on a trailer or a vehicle).
