Definitions

  • the present invention relates firstly to a process for producing impure helium from a feed gas mixture containing helium and other heavier components, of the type in which:
  • the feed mixture is brought to a distillation pressure
  • the feed mixture is cooled at this distillation pressure and introduced into the bottom of a distillation column;
  • the invention applies for example to the production of helium from a waste gas coming from a natural gas liquefier, this waste gas containing, besides helium, methane and nitrogen.
  • the object of the invention is to meet this need in a particularly effective manner.
  • the subject of the invention is a process of the aforementioned type, characterized in that at least one of said components is furthermore produced in the form of a liquid product by implementing a variable-rate closed refrigeration cycle, the rate of which depends on the output of said liquid product.
  • This process may comprise one or more of the following features:
  • the refrigeration cycle is a nitrogen cycle
  • the liquid phase obtained by the second partial condensation is enriched with one of said components and the resulting fluid is recovered as second product;
  • said second product is at least partly liquid
  • the partial condensation of the overhead gas in the column is carried out by heat exchange with pre-expanded liquid from the bottom of the column;
  • distillation pressure is substantially equal to the impure helium production pressure.
  • the subject of the invention is also a unit for implementing the process described above.
  • This unit of the type comprising:
  • a distillation column the bottom of which is connected to the cold end of the heat exchange line and is fitted with a top condenser
  • a heat exchanger suitable for cooling and partly condensing the vapor phase coming from the condensation passages of the top condenser
  • phase separator connected to the cold end of the heat exchanger
  • means for recovering the vapor phase coming from the separator as impure helium product is characterized in that it furthermore includes a variable-rate closed refrigeration cycle for producing a variable output of a liquid product.
  • a pure helium production process characterized in that an impure helium production process as defined above is carried out and the impure helium and said liquid product are sent to a unit for purifying, and optionally liquefying, helium having a cryogenic part;
  • a pure helium production installation characterized in that it comprises an impure helium production unit as defined above and a unit for purifying, and optionally liquefying, helium containing a cryogenic part, this unit being fed with the impure helium produced by the unit and with said liquid product.
  • the installation shown in the drawing comprises an impure helium production unit A and a unit B for purifying the impure helium.
  • This unit B has a cryogenic part, which may be a cryogenic helium purification apparatus and/or a pure helium liquefaction apparatus.
  • the unit A essentially comprises a two-stage feed compressor 1 , a heat exchange line 2 , a distillation column 3 provided with a top condenser 4 , a heat exchanger 5 , two phase separators 6 and 7 and a closed nitrogen refrigeration cycle 8 .
  • the unit A produces impure helium at 25 bar (line 9 ), gaseous nitrogen at 7 bar (line 10 ), liquid nitrogen at 8 bar (line 11 ), a first methane-rich waste W 1 (line 12 ), a second methane-rich waste W 2 (line 13 ) and a nitrogen-rich waste W 3 (line 14 ). All the cold parts of this unit A are contained in the one cold box 15 , which is thermally insulated suitably.
  • a low-pressure (3.9 bar) feed mixture sent via a line 16 , is compressed to 8 bar by the first stage of the compressor 1 and then compressed to 26 bar that is to say slightly above the impure helium production pressure, at the same time as a high-pressure feed mixture sent via a line 17 .
  • the compressed mixture is cooled and partly condensed in the exchange line 2 and introduced into the bottom of the column 3 .
  • the liquid from the bottom of this column is expanded in an expansion valve 18 to approximately 4 bar and introduced into the shell 19 of the condenser 4 , in order to refrigerate the latter.
  • This refrigeration in the condenser 4 causes the overhead gas in the column to partly condense.
  • the uncondensed fraction is an intermediate gas containing approximately 25% helium and 75% nitrogen, with traces of methane.
  • This intermediate gas is cooled and partly condensed in the exchanger 5 and then separated into two phases in the separator 6 .
  • the vapor coming from this separator contains approximately 70% helium. After being warmed in 5 and in 2 , this vapor constitutes the impure helium produced by the unit A, recovered, after being warmed in 5 and then in 2 , via the line 9 . This gas will then be treated in the unit B for purifying, and optionally liquefying, helium.
  • a stream of the liquid contained in the shell 19 is withdrawn via a pump 21 , vaporized and warmed in the exchange line 2 , and then constitutes the other methane-rich waste W 2 , which is discharged via the line 13 .
  • the two methane-rich streams may be utilized, especially for their calorific value.
  • the liquid phase from the separator 6 contains approximately 99% nitrogen. After expansion to 8 bar in an expansion valve 22 , this liquid is introduced into the separator 7 .
  • the liquid phase constitutes the liquid nitrogen production by the unit A, which is conveyed via the line 11 , whereas the gas phase constitutes a nitrogen-rich waste W 3 , containing approximately 95% nitrogen, which is discharged via the line 14 .
  • one portion of the liquid nitrogen is vaporized in the exchanger 5 in order to refrigerate the latter, and then, after being warmed in 2 , it forms the nitrogen gas production stream recovered via the line 10 .
  • the nitrogen refrigeration cycle 8 is a closed cycle with a variable rate independent of the rest of the installation. It comprises a cycle compressor 23 and the combination of a turbine 24 and a supercharger 25 that are mutually coupled.
  • the cycle nitrogen compressed in 23 to 15 bar and supercharged in 25 to 23 bar, is cooled in the exchange line 2 down to an intermediate temperature level and expanded in 24 to 1.6 bar.
  • the nitrogen thus cooled serves to refrigerate the exchanger 5 , then continues to be warmed up in 2 and returns to the intake of the compressor 23 .
  • the refrigeration cycle is not necessary when liquid nitrogen is produced, and the stream of cycle nitrogen is regulated according to the output of liquid nitrogen produced.
  • This liquid nitrogen is at least partly sent via the line 11 to the purification/liquefaction unit B and, optionally, partly withdrawn from the installation via a production line 26 tapped off the line 11 .
  • the unit B fed with impure helium via the line 9 and with liquid nitrogen via the line 11 , produces, via a line 27 , pure, possibly liquid helium and, via a line 28 , a waste gas W 4 .
  • liquid nitrogen production is integrated into the unit A and especially into its cold box 15 .
