    [0001] FIELD OF THE INVENTION The present invention relates to a method of managing a hydrogen dispensing station comprising at least one reservoir containing liquid hydrogen in which any evaporation gas may accumulate. minus one cryogenic pump for compressing the hydrogen at the desired delivery pressure, at least one dispenser for delivering the compressed hydrogen and conduits connecting the components. In the remainder of the description, the term "hydrogen distribution station" designates means for distributing gaseous hydrogen, compressed at the pressure of the tanks equipping mobile or fixed installations and serving to store hydrogen. compressed. STATE OF THE ART In hydrogen dispensing stations, hydrogen in the liquid state inevitably develops evaporation gases which are usually vented to atmosphere without being used or supplied to a gas management system. 'evaporation. For example, such a system consists of a compressor that com- pensates for evaporation to fill an accumulator tank or a small cogeneration plant that burns hydrogen. However, the gases released to the atmosphere are a disadvantage both ecological and economic. Compression of the evaporation gases according to the state of the art is a relatively complicated and expensive operation in terms of installation so that this solution is not economical. Such a solution can not be envisaged for commercial applications at hydrogen distribution stations. OBJECT OF THE INVENTION The object of the present invention is to develop a process for managing a hydrogen distribution station avoiding the drawbacks of known solutions. DESCRIPTION AND ADVANTAGES OF THE INVENTION For this purpose, the subject of the invention is a method of managing a hydrogen distribution station of the type defined above, characterized in that at least part of the evaporation gas accumulated in the storage tank for cooling at least one component and / or a pipe of the hydrogen distribution station and / or this gas is at least partially catalytically burned.
    [0002] According to the invention, the heat capacity of the evaporation gas is used to cool the components and / or the pipes of the hydrogen distribution station. Previously electrical energy has been used to cool and heat such components and ducts.
    [0003] The evaporation gas is advantageously used at least partially to cool the pipe connecting the cryogenic pump and the distributor. The imposed conditions require that the pipe be maintained in a temperature range between -40 ° and -33 ° C.
    [0004] Alternatively or additionally, the evaporation gas is catalytically burned. After the addition of oxygen or a mixture of oxygen-rich gases, for example air, the flameless evaporation gas can be burned in a suitable catalyst. The heat generated by the catalytic combustion of the evaporation gas is advantageously used at least in part to heat the compressed hydrogen by the cryogenic pump which supplies the distributor. According to another development of the process of the invention, the evaporation gas is catalytically burned in a heat accumulator, preferably an aluminum block through which the hydrogen stream flows for heating. The result of this process is that the cryogenic hydrogen pumped, whose temperature is between -220 and -60 ° C at a pressure of 900 bar, will be heated to the desired temperature, for example in general this temperature is equal to -40 ° C. The hydrogen of the evaporation gas is catalytically burned to give water with oxygen from the air that is added or present. This water is evacuated to the environment or the atmosphere in the form of water vapor, by a chimney. Drawings The present invention will be described in more detail below with the aid of an example of a station. hydrogen distribution and advantageous embodiment described in more detail with the aid of an exemplary embodiment shown in the single figure. Description of Embodiments The single figure shows the main components of a hydrogen dispensing station. It is more precisely a tank S which contains hydrogen in the liquid state, a cryogenic pump C for compressing hydrogen at the desired distribution pressure and a distributor D which distributes the compressed hydrogen to feed a tank of mobile or fixed equipment. The lines 1-4 connect the components mentioned above as shown.
    [0005] The liquefied hydrogen taken from the tank S via the line 1 is compressed in the cryogenic pump C at the appropriate distribution pressure, for example at a pressure of between approximately 750 and 900 bar. The compressed hydrogen, the temperature of which is exemplary, of between -220 and -60 ° C. passes through the aluminum block T via line 2. This block heats up to a temperature of, for example, -40 ° C. compressed hydrogen supplied by the pipe sections 3 and 4, the distributor D which feeds the pressure accumulator tank not shown in FIG. 1 by the filling pipe 5.
    [0006] The evaporation gas 6 which accumulates in the tank S is divided into two partial flows 7 and 10 according to the embodiment of FIG. 1. The first partial flow 7 of evaporation gas feeds a catalyst K into the aluminum block T after addition of air 8 to be catalytically burned therein and escape to atmosphere through line 9. The heat developed in catalyst K during catalytic combustion is accumulated in the block of aluminum T and warms the hydrogen flow rate 2 which passes continuously or discontinuously in the aluminum block T. If the heat capacity of the partial flow 7 of evaporative gas burned catalytically does not allow to heat up the flow rate of hydrogen 2 to the desired temperature, it is necessary to use an additional heating device not shown in Figure 1, for example an electric heater. The second partial flow of evaporation gas 10 serves to cool (as indicated by the heat exchanger E) the duct sections 3 and 4 connecting the cryogenic pump C and the distributor D. As already described these sections of pipe must be maintained at a temperature between -40 and -33 ° C, for example to meet the required boundary conditions. After having been cooled in the pipe sections 3 and 4, the partial flow of evaporation gas is discharged to the environment via the pipe 11 or is catalytically burned. The method of management of a hydrogen distribution station according to the invention makes it possible to use the energy and the enthalpy of the evaporation gases. It is particularly advantageous that the amount of electrical energy required by the operation of the hydrogen dispensing station is significantly reduced by this use since the cooling and heating have been carried out in advance substantially by the cooling and the electric heating device. In addition, the method according to the invention for managing the hydrogen distribution station is of simple construction, easy to control and to scale up.25 NOMENCLATURE OF THE MAIN ELEMENTS 1-4 Driving 3, 4 Driving sections 5 Filling line 6 Evaporating gas 7, 10 Partial flow 8 Addition of air C Cryogenic pump D Dispenser S Tank T Aluminum block15
