Definitions

  • the invention relates to a method and an installation for filling a pressure tank with a gas.
  • the document GB 987019 describes an installation and a method of filling.
  • the filling can be carried out with a mechanical compressor, preferably of the membrane type, to avoid any pollution.
  • Membrane compressors are very heavy and only allow low gas flows, so filling a tank can be very long.
  • hydropneumatic booster present risks of gas pollution, which is not acceptable for certain applications envisaged, especially in the space field.
  • This method is not suitable for tanks in composite or raw steel, or for tanks already integrated within a structure such as, for example, a satellite. It is also possible to consider heating the mother bottle containing the gas, but this method is applicable if the volume of the tank to be filled is much lower than that of the mother bottle.
  • the aim of the invention is to provide a method and an installation for filling a pressurized tank which obviates the abovementioned drawbacks of the known techniques and makes it possible to reliably fill, which can be used, on a launchers pitch, without risk of pollute the xenon.
  • the intermediate container serves as a thermal compressor, that is to say, can raise the pressure of the gas relative to its pressure in a source such as a mother bottle.
  • This thermal compressor is light, powerful compared to other solutions, and does not include moving parts, which is a guarantee of good reliability.
  • the method also consists in heating the quantity of gas in the intermediate container, after the fluid connection of the intermediate container and the reservoir. Thanks to this aspect of the invention, when the communication between the intermediate container and the reservoir has been made, the maintenance of the heating leads to a heating of the quantity of gas included in the intermediate container, which makes it possible to discharge continuously to the reservoir this amount of gas which is then under high pressure.
  • the transfer of gas from the intermediate container to the reservoir takes place at substantially constant pressure.
  • the refrigeration liquid used with the process of the invention is advantageously liquid nitrogen whose industrial production is well controlled.
  • the invention also relates to an installation for implementing the method of the invention and, more specifically, an installation which comprises at least one compressor thermal formed of an intermediate container disposed between a source of gas and the tank, the thermal compressor comprising means for liquefaction by cooling a quantity of the gas being introduced into the intermediate container and heating means of this amount of gas inside the intermediate container.
  • the liquefaction means comprise a circulation tube of a cooling liquid such as, in particular, liquid nitrogen.
  • a cooling liquid such as, in particular, liquid nitrogen.
  • the means for heating the quantity of gas included in the intermediate container comprise an electric heating element.
  • an electric heating element allows a rapid heating of the amount of gas included in the intermediate container, and therefore a substantial decrease in the cycle time of a filling operation compared to known techniques.
  • the circulation tube and the electric heating element are placed inside the intermediate container.
  • the thermal compressor sees its temperature decrease or increase depending on that of the fluid it contains, so that the thermal inertia of the compressor is reduced.
  • the intermediate container comprises a gas inlet in its lower part and a gas outlet in its upper part. This allows a withdrawal of the gas in the part of the intermediate container in which the temperature of the gas is highest.
  • the intermediate container may contain a cup for receiving the liquefied gas, this cup being distant from the inner wall of the container. Thanks to this aspect of the invention, the thermal inertia of the compressor is also reduced.
  • the invention also relates to an installation which comprises two thermal compressors able to operate in opposition, one working on the liquefaction of a quantity of gas while the other works on the vaporization-compression of another quantity of gas. This makes it possible to carry out the liquefaction operations in masked time, and thus to reduce the total duration of a filling operation of a tank.
  • a mother bottle 1 contains a quantity of xenon, for example 50 kg, at a pressure of the order of 60 bars at 20 ° C.
  • the role of the installation is to fill a tank 2 of titanium, steel or carbon, intended to be embedded on a satellite, at a pressure of between 80 and 300 bar approximately, for example of the order of 180 bar.
  • the installation comprises an intermediate container 3 whose inlet 3a is connected via a pipe 4 through a valve 5, to the mother bottle 1.
  • a line 6 connects the output 3 b from the intermediate container 3 to the tank 2 through a valve 7.
  • the container 3 comprises an enclosure 3c defining an interior volume 3 d of the exchanger 3, of the order of a few liters, for example about 4 liters.
  • a tube 10 inside which circulates liquid nitrogen from a source 11 such as a liquid nitrogen cylinder.
  • a valve 12 is provided for controlling the supply of the tube 10 from the source 11.
  • a collection member 13 is provided to receive the liquid or gaseous nitrogen after it has circulated in the tube 10.
  • An electric heater such as for example a heating resistor 15, is also arranged inside. of the volume 3 d and connected to a source of potential 16 being controlled by a switch 17.
  • the tube 10 is spirally wound with a generally vertical axis, while the heating element 15 is also spirally wound inside the volume 3 d about the same axis.
  • a cup 20 is disposed inside the intermediate container 3 around the tube 10 while being kept at a distance from the inner wall of the enclosure 3c by spacers 21.
  • This cup 20 is intended to receive the liquefied gas, such that the latter is kept at a distance from the enclosure 3c , which makes it possible to reduce the heat exchange and therefore the thermal inertia of the container 3.
  • the inlet 3 a of the xenon is arranged in the lower part of the tundish 3, whereas the outlet 3b is arranged in the upper part.
  • the arrows LN 2 indicate the flow direction of the nitrogen
  • the arrows X e indicate the flow direction of the xenon
  • the arrow Q e indicates the amount of electricity supplied to the resistor 15.
  • the valve 7 When it is desired to fill the tank 2 from the cylinder 1 containing xenon, the valve 7 being closed, the valve 5 is opened to put the mother bottle 1 and the intermediate container 3 in communication, so that the gas is discharged from the bottle 1 to the tank 3.
  • the tube 10 As the gas enters the tank 3, the latter is liquefied by contact with the tube 10 in which circulates liquid nitrogen at about -180 ° vs.
  • the diameter of the tube 10 and the flow rate of the liquid nitrogen in this tube are calculated so that the consumption of liquid nitrogen is not too great and for the nitrogen to exit the intermediate container 3 at a temperature close to the saturation temperature of xenon, 165K at 1 bar.
  • the flow rate of liquid nitrogen in the tube 10 is between 2 and 20 g / s.
  • the valve 5 and the switch 17 are then closed so that the circulation of the current inside the resistor 15 results in a rapid rise in the temperature of the xenon contained in the container 3. This induces a vaporization of the gas liquefied, then compression of this gas inside the container 3, this compression to quickly reach a pressure of the order of 180 bar.
  • the intermediate container 3 is therefore a "thermal compressor" for raising the pressure of a gas and having no moving part.
  • valve 7 When a pressure of the order of 180 bar is reached, the valve 7 is opened so as to put in fluid communication the container 3 and the tank 2. The gas is then discharged into the tank 2.
  • the switch 17 is kept closed, so that the heating continues inside the intermediate container 3, which tends to increase the pressure inside the tank 3, the gas then being progressively discharged.
  • the discharge of the gas from the intermediate container 3 to the tank 2 takes place while the pressure inside the intermediate container is kept substantially constant, or even increases slightly.
  • An exchanger 22 having high thermal inertia is disposed around the pipe 6.
  • This exchanger which may be formed of an aluminum block, is adapted to receive, as input, a gas between -30 ° C and 40 ° C and to deliver, at the outlet, a gas at about 5 ° C. This allows to feed the tank 2 at a temperature above 5 ° C and to avoid any risk of condensation in or on the external surface of the tank 2.
  • the heat compressor or intermediate container 3 must be able to withstand low temperatures when the gas is liquefied, but also be sized according to the pressure to which the tank 2 must be filled.
  • the thickness of the enclosure 3 c is determined according to these criteria.
  • the thermal inertia of the compressor must be as low as possible so as not to penalize the performance of the process and, in particular, the cycle time.
  • the volume of the compressor must be large enough to accommodate the tube 10 and the heating element 15, but not too large so as to limit the thermal inertia.
  • a volume of a few liters, especially 4 to 6 liters, can fill a tank of a few hundred liters in a few tens of cycles.
  • the wall of the thermal compressor 3 may have a thickness of about 10 mm, its total mass being of the order of about 30 kg.
  • the compressor is equipped with a pressure sensor and a temperature sensor, which are not shown in the figures, to verify the proper operation of the device.
  • the thermal compressor 3 can be installed on a scale.
  • the power dissipated by the heating element 15 is not necessarily very important insofar as the amount of fluid to be heated for each cycle is relatively small. In practice, a heating element with a nominal power of the order of a few kilowatts, for example between 2 and 4 kW, is sufficient.
  • compressors can be used in parallel to increase the total flow of the installation.
  • two thermal compressors operating in opposition, one working to the liquefaction of a quantity of gas while the other works to the vaporization-compression of another amount of gas.
  • the heating element 15 could be replaced by a water exchanger or other fluid with a high heat capacity.
  • the arrangement of entries 3 and 3b as well as the arrangement of the inlet and outlet 10 and the inlet tube and outlet of the heating element 15 could be modified.
  • a refrigeration system with a fluid having a vaporization temperature close to 200K could be used in place of the tube 10 containing liquid nitrogen.
  • the invention has been presented with a tank filling plant with xenon. It is understood that it is applicable with other gases with a relatively high critical temperature and, in particular, with krypton.
  • a preferred field of application of the invention is the ground filling of a xenon reservoir having a purity greater than 99.995, this xenon being used for the plasma propulsion of the satellites. It is understood that the installation of the invention can be a lightweight and compact assembly that can be easily moved on the firing points of these satellites.
  • the invention can also be used in xenon or krypton recovery plants, for example in the lamp industry.
