  • turbo compressors For the compression of the circulating in the refrigerant (mixture) cycle refrigerant or refrigerant mixture usually turbo compressors are used.
  • the control concept of these compressors is speed, bypass or suction throttle control.
  • compressors in which a side feed is realized compressor constructions are to be understood, in which the refrigerant to be compressed or refrigerant mixture is supplied to the compressor in the form of multiple partial streams.
  • the mixing of the partial flows is carried out either by an internal admixture within the compressor or an external admixture in the piping.
  • the partial flows to different pressure levels and are compressed to a common final pressure.
  • double-flow machines or compressors are to be considered, in which the refrigerant or refrigerant mixture to be compressed is supplied in the form of two partial streams of the same suction pressure, which are compressed to a common final pressure.
  • Object of the present invention is to provide a generic method for cooling or liquefying a hydrocarbon-rich stream, in particular a natural gas stream, which avoids the aforementioned disadvantages.
  • a generic method for cooling or liquefying a hydrocarbon-rich stream is specified, which is characterized in that the refrigerant or refrigerant mixture is compressed by means of at least one Vorleitgitter-controlled single-shaft turbocompressor radial design.
