Definitions

  • the invention relates to a method by cryogenic separation of air, in particular for the production of gaseous pressure oxygen.
  • the distillation column system of the invention may be designed as a two-column system (for example as a classic Linde double column system), or as a three-column or multi-column system.
  • other devices may be provided to recover other air components, particularly noble gases, such as argon or krypton-xenon recovery.
  • the invention relates to a process in which at least one gaseous pressure product is recovered by withdrawing a liquid product stream from the nitrogen-oxygen separation distillation column system, raising it to an elevated pressure in the liquid state, and evaporating it under this increased pressure by indirect heat exchange or (at supercritical pressure) is pseudo-evaporated.

  • the invention has for its object to make such a method and a corresponding device economically particularly favorable.
  • the drive of the cold compressor through the first expansion machine is particularly energetically particularly favorable.
  • the feed air has a pressure potential which would create more refrigeration in the expansion machine (s) than can be used in the process.
  • the excess energy is used in the invention for driving the cold compressor, which brings the second partial flow of the feed air to a particularly high pressure.
  • the method has a second expansion machine, in which a third partial flow of the feed air is expanded to perform work.
  • the outlet pressure of the second expansion machine is, for example, approximately at the level of the low-pressure column or the high-pressure column. Depending on the relaxed air is introduced into the low pressure column or in the high pressure column.

  • the cold high-pressure air 20 is expanded in a throttle valve 21 to approximately the operating pressure of the high-pressure column 11, which is for example 5 to 7.5 bar, preferably 5.5 to 6 bar, and introduced into the high-pressure column. At least a portion of the introduced liquid air is removed again via line 22, cooled in a subcooling countercurrent 23 and fed via line 24 and throttle valve 25 in the low pressure column 12.

  • FIG. 2 is different from this FIG. 1 in that the discharge pressure of the second expansion machine 130 is higher, namely at the level of the operating pressure of the high-pressure column 11. Consequently, the work-performing relaxed third partial stream 131 is here combined with the cold fourth partial stream and fed via line 132 of the high-pressure column 11.
  • liquid products are obtained by withdrawing a portion 136 of the liquid oxygen from the bottom of the low-pressure column 12 as liquid oxygen product (LOX) and a portion of the liquid nitrogen 142a, 142b produced in the main condenser 13 as liquid nitrogen product (LIN).

  • Return liquid 139-140 -141 for the low-pressure column 12 is taken from the high-pressure column 11 here at an intermediate point.
  • the inner-to-be-compressed liquid oxygen 46 is withdrawn at a lower purity of about 95% from an intermediate point of the low-pressure column 12.
  • a second, purer oxygen product 346, 348, 349 can be recovered by internal compression (second oxygen pump 347). Because of the pure oxygen production, the air pressure must be slightly higher than in the above-described embodiments. It is for example 6 to 7.5 bar, preferably 6 to 7 bar.
