  • the "main heat exchanger system” serves to cool feed air in indirect heat exchange with return streams from the distillation column system. It may be formed of one or more parallel and / or serially connected heat exchanger sections, for example one or more plate heat exchanger blocks.
  • post-compression system is here a system of at least two serially connected stages (hereinafter also referred to as “compressor stages”).
  • compressor stages serially connected stages
  • the invention has for its object to provide a method of the type mentioned above and a corresponding device, which are economically particularly favorable to operate by having an increased product yield, higher product purity, lower operating costs and / or lower investment costs.
  • the adiabatic mode of operation of the recompression system ie the absence of any intercooling between its stages, not only leads to an apparatus saving, but also to an overall very efficient process.
  • the second intermediate temperature at which the second air stream is supplied to the secondary compression system is below the temperature of the warm end of the main heat exchanger system, in particular by at least 10 K. It is for example 230 to 270 K.
  • the distillation column system of the invention preferably comprises a high pressure column and a low pressure column.
  • the first pressure to which the total air is compressed is at least 5 bar, preferably at least 10 bar higher than the operating pressure at the top of the high-pressure column.
  • the work-performing expansion of the first air flow is performed in two parallel relaxation machines, with a two expansion machines with the last stage of the secondary compression system and the other of the two expansion machines with another stage of the secondary compression system is directly mechanically coupled
  • Parallel connection here means that the two expansion machines have the same inlet pressure. Preferably, they also have the same inlet temperature and the same outlet pressure. Alternatively, they are operated with different inlet temperatures and / or with different outlet pressures.
  • Pressures are referred to herein as "equal" when the pressure differential between the respective locations is not greater than the natural conduction losses due to pressure losses in piping, heat exchangers, coolers, adsorbers, etc. Similarly, two streams are at the same temperature even if their temperature differs by a value corresponding to a temperature difference due to natural variations or to common insulation losses along a pipe.
  • the expansion machines are formed for example by turbines, each with a turbine wheel.
  • a “direct mechanical coupling” here means a direct connection between the expansion machine and the after-compressor stage via a common shaft, in particular not via a transmission.
  • one of the expansion machines must be coupled to a warm braking device, ie to a dissipative brake (for example oil brake), to a generator or to a warm compressor for generating process refrigeration.
  • a dissipative brake for example oil brake
  • This can be realized by using a corresponding third expansion machine, which is not coupled to any of the stages of the Nachverdichtungssystems, or in that on the shaft of one of the above-mentioned expansion machines additionally an oil brake or a generator is arranged.
  • the second air stream is cooled downstream of the Nachverdichtungssystems in an aftercooler in indirect heat exchange with cooling water before it is fed to the warm end of the main heat exchanger system.
  • a part of the mechanical energy generated in the expansion machine which is coupled to the last stage of the Nachverdichtungssystems, are released into the warm.
  • the corresponding expansion machine generates both the energy required for driving the last stage and at least a portion of the required process cooling.
