- the invention may also relate to any alternative device or method comprising any combination of the characteristics above or below within the scope of the claims.
- FIG. 1 represents a schematic and partial view illustrating a first example of the structure and operation of a filling device according to the invention
- FIG. 2 represents a schematic and partial view illustrating a second example of the structure and operation of a filling device according to the invention.
- the device 1 for filling pressurized gas tanks illustrated in [Fig. 1] can be used in particular for filling pressurized hydrogen tanks.
- This device comprising a source 2 of pressurized gas (pressurized storage (s), liquid storage (s) associated with a pump and / or a vaporizer, electrolyser (s), etc.).
- pressurized storage s
- liquid storage s
- electrolyser s
- the filling device 1 comprises a transfer pipe 3 having an upstream end connected to the at least one source 2 and at least one downstream end intended to be connected to a reservoir 4 to be filled. Of course, several downstream ends can be provided to simultaneously fill or not several separate reservoirs 4.
- the transfer line 3 can conventionally comprise a set of valve (s) 5 for controlling the flow of gas from the souOrce 2 towards the downstream end, for example a piloted valve 5 for controlling the flow and / or the pressure.
- Other members can conventionally be provided on this transfer pipe 3, in particular at least one of: gas cooling member, isolation valve, pressure and / or temperature sensor (s).
- the transfer line 3 comprises at least one compressor 6 and the device 1 comprises a sensor 11 for detecting the presence of oil in the gas flowing in the transfer line 3 downstream of the compressor 6.
- the device 1 comprises a bypass line 7 connected to the transfer line 3 downstream of the compressor 6.
- the bypass line 7 preferably comprises a set of at least two valve (s) 8, 9, 10 in series configured to allow, in a first configuration, the sampling of gas flowing in the transfer line 3 in the bypass line 7 and, in a second configuration, the fluidic insulation between the bypass line 7 and the transfer line (3).
- the valve assembly (s) 8, 9, 10 of the transfer line 3 defines in the second configuration a closed storage volume for the gas withdrawn and trapped in the bypass line 3.
- the closed storage volume comprises a system for reducing the gas pressure taken at very high pressure and trapped in the bypass line 3 to lower the pressure of the gas trapped to a pressure lower than the pressure of the gas circulating in the transfer line 3 .
- the sensor 11 for detecting the presence of oil measuring the presence of oil in said closed storage volume, that is to say that it is exposed to a pressure less than that of the gas circulating in the pipe 3 transfer. That is to say that very high pressure gas is taken from the outlet of the compressor 6 and is expanded before detecting the possible presence of oil there.
- the bypass pipe 7 comprises an upstream end connected to the transfer pipe 3 downstream of the compressor 6 and a downstream end.
- the bypass pipe 7 comprises, arranged in series between its upstream and downstream ends: a first isolation valve 8, a second isolation valve 9 and a third isolation valve 10.
- the first isolation valve 8 In normal operation (when filling a tank 4 for example), the first isolation valve 8 is open and the second isolation valve 9 is closed. If oil is contained in the very high pressure gas supplied by the compressor, this oil will enter with the gas which contains it in the volume of the bypass pipe 7 located between the first 8 and second 9 isolation valves .
- a filter 18 can be placed at the intersection between the transfer line 3 and the bypass line 7 and / or in the bypass line 7 to collect this possible oil.
- the first isolation valve 8 can be closed and then the second isolation valve 9 can be opened.
- the small volume of hydrogen and oil trapped will expand into a larger closed storage volume. This can be achieved by providing downstream of the second isolation valve 9 pipes of larger diameter and / or a length of pipes sufficient to increase the volume for the trapped gas.
- the bypass pipe 7 may include an increase in the section 13 of its piping downstream of the second isolation valve 9.
- the pressure downstream of this second isolation valve 9 may be relatively lower than in the transfer line 3, for example less than 200 bar.
- the volume between the first two isolation valves 8, 9 and the closed storage volume when the second isolation valve 9 is open can be sized relatively to decrease the pressure in the closed storage volume below the value of maximum pressure that the sensor can tolerate 11.
- the senor can detect the possible presence of oil without being exposed to too much pressure.
- the trapped gas When the detection has been made, the trapped gas must be evacuated for another measurement.
- the device may include a pipe 16 for discharging the gas trapped in the closed storage volume.
- This bypass pipe 7 may include an upstream end connected to the bypass pipe 7 in the closed storage volume (for example between the second 9 and third 10 isolation valves).
- the bypass pipe 7 comprises a downstream end connected to a discharge volume.
- the discharge line 16 comprises a set of isolation valve (s) 17.
- downstream end can be connected to an evacuation zone (vent to the atmosphere for example) and / or to the inlet of the compressor 6 in order to recycle the gas there.
- This gas could also be returned to the source 2 of pressurized gas.
- This evacuation of the closed storage volume can for example lower the pressure to a determined value, for example 15 bar.
- All or part of the valves can be piloted valves which can be controlled automatically by an electronic controller comprising a data storage and processing member such as a microprocessor or a computer for example.
- the process can be automated.
- the test (measurement to detect the presence of any oil) can be done at any time before filling or during filling, periodically at each filling, several times per filling or according to any other frequency.
- the device can be configured to generate a corresponding signal to signal that the gas leaving the compressor 6 is polluted. In this case, it may not be necessary to repeat the test.
- the generated signal can interrupt the operation of the compressor and / or warn operators for an intervention.
- the optoelectronic level sensor can be replaced or supplemented by a pipe, part of which is transparent. This allows operators to watch the presence or absence of oil (and save the cost of the sensor if necessary).
- the downstream end of the bypass pipe 7 can be connected to an oil recovery member 14.
- the third isolation valve 10 can be opened to discharge the collected oil.
- a calibrated orifice 12 can be arranged in the bypass line 7 downstream of the second isolation valve 9. This allows a gradual increase in pressure downstream to save the material.
- a pressure sensor 15 can be provided to measure the pressure in the closed storage volume of the bypass pipe 7 (in particular between the second 9 and third 10 isolation valves).
- the invention is not limited to the examples described above. For example, it may be considered to eliminate the second valve 9 for isolating the bypass pipe 7 in certain configurations.
- the second valve 9 can be omitted.
- the first isolation valve 8 is open when the compressor 6 is running.
- the high pressure gas is admitted into the bypass line 7 through a calibrated orifice and can be subjected to oil detection in the volume located between the first valve 8 and the end valve 10.
