Definitions

  • the present invention relates in the first place to a process for producing pure helium.
  • the invention applies for example to the production of helium from a residue gas of natural gas liquefier, the waste gas containing, besides helium, methane and nitrogen.
  • the pressures here are absolute pressures.
  • the invention aims to meet this need in a particularly effective manner.
  • the subject of the invention is a method according to claim 1.
  • the invention also relates to a unit according to claim 8.
  • Figure unique schematically shows a helium production facility according to the invention.
  • the plant shown in the drawing comprises an impure helium production unit A and a unit B for purified helium purification.
  • This unit B comprises a cryogenic part, which may be an apparatus for the cryogenic purification of helium and possibly an apparatus for liquefying pure helium.
  • Unit A essentially comprises a feed compressor 1 with two stages, a heat exchange line 2, a distillation column 3 provided with a head condenser 4, a heat exchanger 5, two phase separators 6 and 7, and a closed nitrogen refrigeration cycle 8.
  • Unit A produces impure helium at 25 bar (line 9), nitrogen gas at 7 bar (line 10), liquid nitrogen at 8 bar (line 11), a first waste W1 rich in water. methane (line 12), a second waste W2 rich in methane (line 13), and a residual W3 rich in nitrogen (line 14). All the cold parts of this unit A are contained in the same cold box 15 suitably thermally insulated.
  • a mixture of low pressure feed at 3.9 bar, brought by a line 16 is compressed to 8 bar by the first stage of the compressor 1, and then it is compressed to 26 bars, that is to say slightly above the impure helium production pressure, together with a mixture of high-pressure feed, brought by line 17.
  • the compressed mixture is cooled and partially condensed in the exchange line 2 and is introduced into the bottom of the column 3.
  • the bottom liquid of this column is expanded in an expansion valve 18 at about 4 bar and introduced into the shell 19 condenser 4 to refrigerate it.
  • the uncondensed fraction is an intermediate gas containing about 25% helium and 75% nitrogen, and traces of methane.
  • This intermediate gas is cooled and partially condensed in the exchanger 5, then separated in two phases in the separator 6.
  • the vapor from this separator contains about 70% helium. After heating to 5 and 2, this steam is the impure helium production unit A, recovered, after heating in 5 and 2, via the pipe 9. This gas will then be treated in the unit B purification, and possibly liquefaction, helium.
  • a flow rate of the liquid contained in the shell 19 is drawn off by a pump 21, vaporized and heated in the exchange line 2 and then constitutes the other waste W2 rich in methane, which is discharged via the pipe 13.
  • the liquid phase of the separator 6 contains about 99% nitrogen. After expansion at 8 bar in an expansion valve 22, this liquid is introduced into the separator 7.
  • the liquid phase constitutes a production of liquid nitrogen from the unit A, conveyed via line 11, whereas the gaseous phase constitutes a residual W3 rich in nitrogen, about 95% nitrogen, which is evacuated via line 14.
  • the nitrogen refrigeration cycle 8 is a closed variable rate cycle independent of the rest of the installation. It comprises a cycle compressor 23 and a 24-blower turbine assembly 25 coupled to each other.
  • the ring nitrogen compressed in 23 to 15 bar and overpressed in 25 to 23 bar, is cooled in the line exchange 2 to an intermediate temperature level and expanded to 24 to 1.6 bar.
  • the nitrogen thus cooled serves to cool the exchanger 5, then continues its heating in 2 and returns to the suction of the compressor 23.
  • the cycle nitrogen flow is adjusted according to the flow of liquid nitrogen produced.
  • This liquid nitrogen is at least partly sent via the pipe 11 to the unit B of purification / liquefaction, and possibly partially out of the installation via a production line 26 stitched on the pipe 11.
  • Unit B fed with impure helium via line 9 and liquid nitrogen through line 11, produces pure helium, possibly liquid, via line 27, and a waste gas W4 via line 28.
  • liquid nitrogen is integrated in the unit A and in particular in the cold box 15 thereof.
