Definitions

  • the present invention relates to a helium reliquefaction process gas produced during the transfer of liquid helium from a donor container to a container recipient.
  • the cold helium vapors are recovered and packaged in equipment called CCH (helium conditioning centers) essentially comprising a multi-stage compression module capable, for example, of filling bottles with helium gas at a pressure of 200x10 5 Pa.
  • CCH helium conditioning centers
  • the present invention aims to provide a method for improving economically the ratio of liquid transferred between the donor container and the container receiving by reliquefaction of at least part of the cold vapors helium produced during its transfer.
  • the process of liquefying helium gas produced during its transfer from a donor container to a recipient container is characterized in that takes a stream of helium gas at a point on a compression module intended when conditioning gaseous helium under pressure, this helium stream is cooled gas compressed by heat exchange with helium gas intended for said module compression, and the compressed helium gas thus cooled is expanded to obtain reliquified helium.
  • the installation is intended to transfer liquid helium from a container donor R1, where it is stored under pressure P1, at another storage R2, typically a much smaller receiving container, under pressure P2 ⁇ P1.
  • P1 is of the order of a few bars and P2 is close to the pressure atmospheric.
  • the installation includes a pipe 1 suitable for transport liquid helium, which is connected to the bottom of the R1 helium container liquid in order to transport the helium towards a phase separator 2.
  • the line 1 is fitted before the phase separator 2 with an expansion valve 3.
  • the phase separator 2 has at its top a first pipe of outlet 5.
  • the latter passes through an indirect counter-current heat exchanger 8.
  • the pipe 5 is provided with a heater 9 with atmospheric air before communicating with the aspiration of a compression module 10 of the CCH type, as described above.
  • the module 10 compresses the gaseous helium in the vicinity of the ambient temperature coming from the line 5 to a pressure P 3 of the order of 15 to 20 ⁇ 10 5 Pa.
  • the module 10 comprises an outlet line 11 provided with a water cooler 12 and a flow distributor 13.
  • the latter has a first outlet pipe 14 for conditioning helium bottles under high pressures of the order of 200 ⁇ 10 5 Pa, with recompression, and a second pipe outlet 15 which crosses the countercurrent exchanger 8, in heat exchange relation with the pipe 5.
  • the pipe 15 is provided after the exchanger 8 with a valve 16 of the JT type (Joule-Thomson) before lead to the interior of the phase separator 2.
  • the latter has in its lower part and opposite the pipe 5 another outlet pipe 17, connected to the storage R2.
  • the helium leaving the donor container R1 is brought in, by means of the line 1, to phase separator 2, after expansion to pressure P2 in the valve 3.
  • the helium gas contained in the separator 2 resulting from the expansion in 3 and heat losses from line 1, is then transported by means of the line 5 through the countercurrent exchanger 8 and brought back to the vicinity of the ambient temperature at 9, to arrive at the suction of the compression module 10.
  • the helium gas is taken from a point of the compression module 10 to have a pressure level P 3 compatible with the cooled reliquefaction near ambient temperature at 12, and is transported, by means of the pipe 11, to the level of the flow distributor 13.
  • P 3 pressure level compatible with the cooled reliquefaction near ambient temperature at 12, and is transported, by means of the pipe 11, to the level of the flow distributor 13.
  • the latter makes it possible to bring the compressed gaseous helium either in the direction of the line 14 to be supercharged and packaged in bottles, or in the direction of the line 15 which passes through the exchanger 8.
  • the helium gas compressed at the pressure P 3 , conveyed by the line 15 is cooled inside the exchanger 8, by means of the gaseous helium flowing against the current in the line 5.
  • the compressed helium gas thus cooled is then transported by the same line 15 at the level of the valve 16 of the JT type (Joule-Thomson) so as to be relaxed there from the pressure P 3 to the pressure P 2 , and partially liquefied.
