Definitions

  • the invention relates to a cryogenic fluid storage device.
  • the invention relates more particularly to a cryogenic fluid storage device comprising a tank extending in a longitudinal direction and intended to contain liquefied gas in equilibrium with a gaseous phase, a tank pressurization device, the pressurization device comprising a pressurized gas generator and a pressurized gas injection rail extending in the longitudinal direction in the upper part of the tank, the injection rail comprising a plurality of gas outlet orifices spaced in the longitudinal direction.
  • the tank In certain applications, to withdraw liquid from a cryogenic tank, the tank must be pressurized beforehand so as to present a pressure difference sufficient for the transfer. In addition, this pressure must also be maintained during the transfer.
  • an atmospheric heater is placed under the tank to allow pressurization by vaporizing part of the liquid contents of the storage.
  • the vaporized and superheated gas is then reinjected into the gas overhead of the reservoir. See for example the document FR1402554A .
  • An object of the present invention is to overcome all or part of the drawbacks of the prior art noted above.
  • the device according to the invention is essentially characterized in that at least one of: the spacing between the orifices, the diameter orifices, the number of orifices is different along the longitudinal direction between a first gas inlet end in the ramp and a second opposite end of the ramp and configured to homogenize the flow rates leaving the orifices of the ramp along the longitudinal direction.
  • the gas reinjection velocity field obtained is more homogeneous than according to the prior art and makes it possible to concentrate the heat at the top of the gas dome, while disturbing the boundary layer at the liquid/gas interface as little as possible. The stratification of the gaseous sky is improved.
  • 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.
  • the cryogenic fluid storage device 1 illustrated by way of example comprises a reservoir 2, for example of generally cylindrical shape, extending in a longitudinal direction A which is preferably horizontal when the reservoir 2 is in the configuration of use.
  • the tank 2 is of the cryogenic type, that is to say configured to contain liquefied gas 3 (a liquid phase in the lower part surmounted by a gaseous phase in the upper part).
  • the device 1 further comprises a device 5, 6 for pressurizing the reservoir 2.
  • This pressurizing device conventionally comprises a pressurized gas generator 5 fluidly connected to a pressurized gas injection ramp 6 extending in the longitudinal direction A in the upper part of the tank 2. That is to say that the injection rail is located in the upper half of the tank, in particular adjacent to the upper end of the tank. The injection rail is thus located in the gaseous phase of the reservoir.
  • the pressurized gas generator 5 may for example comprise a heater for the fluid taken in liquid form from the reservoir 2. The generator is configured to supply the injection ramp 6 with pressurized gas.
  • the injection ramp 6 is fixed by plates 9 at the level of the upper surface of the tank 2.
  • the ramp 6 is located at a distance from the highest part of the tank 2 of between 10mm and 200mm .
  • the injection rail 6 is provided with a plurality of gas outlet orifices 7 distributed along the longitudinal direction A.
  • the spacing D1, D2,... between the orifices 7 and/or the diameter d0, d1, d2,... (or the section) and/or the number of the orifices 7 varies according to the longitudinal direction A between a first gas inlet end in the ramp 6 and a second opposite end of the ramp 6, so as to homogenize the flow rates leaving the orifices 7 of the ramp 6 in the longitudinal direction A.
  • the ramp 6 preferably crosses the entire gas headspace of the tank 2 (over its entire length or the majority of its length).
  • At least some of the orifices 7 have identical diameters (or sections) d0, d1, d2 and decreasing spacings D1, D2 from the first end towards the second end of the ramp.
  • At least a part of the orifices 7 have increasing diameters d0, d1, d2, etc... and constant spacings D1, D2, etc... from the first end towards the second end of the ramp. These increasing diameters or sections can also be obtained, for example, by varying the number of orifices 7.
  • the sum of the surfaces of all the orifices 7 can be equal to the surface of the inlet section of the gas flow in the ramp 6.
  • the second end of the ramp 6 preferably comprises a flow control member 8 from among: a convergent, a divergent, an orifice.
  • This regulating member 8 is configured to contribute to controlling the flow rate and the injection speed at the end of ramp 6.
  • the ramp 6 may comprise groups of several orifices 7 at one or more longitudinal positions.
  • orifices 7 of the same group or of two different groups can be oriented separately towards the inside of the tank 2.
  • orifices 7 are located oppositely on either side of the periphery of ramp 6 (jets oriented laterally on each side downwards in the tank 2) cf. [ Fig. 3 ] and/or towards the top of the tank (see [ Fig. 3 ]) and/or the orifices are oriented laterally substantially horizontally cf. [ Fig. 4 ].
  • the orientation of the orifices 7, giving the inclination to the gas jet makes it possible to reduce the appearance of convective cells and/or to reduce the heat exchanges at the wall of the reservoir 2.
  • the orifices can be positioned symmetrically or not on the ramp 6.
  • the ramp 6 may include, near the first end, an elbow 19 located above at least part of the remainder of the ramp 6 extending towards the second end.
  • this bend 19 could be formed outside the reservoir 2, for example at the level of the pipe portion which supplies the ramp 6 with gas.
  • the device allows the reduction of pressurization times in tank 2.
  • Heat transfers inside tank 2 are also reduced at the liquid/gas interface. There is also a potential reduction in the heating of the liquid present in tank 2 via a stratification of the gas dome (thanks to the homogenization and reduction of the reinjection velocity field).
