Definitions

  • the present invention providing a method of cooling a hydrocarbon stream such as natural gas, the method at least comprising the steps of:
  • the gaseous stream 130 is compressed via compressor 22, which may comprise one or more compressors, to provide a compressed gaseous stream 150.
  • the compressed gaseous stream 150 may then be cooled (not shown), prior to being divided by a divider 24 into a first stream 170 and a second stream 160.
  • the division of the compressed gaseous stream 150 may be based on any ratio of mass, volume or molecular weight.
  • the first liquid stream 30 passes through a valve 36 and into a second gas/liquid separator, an example of which is a deethanizer 38.
  • Table 2 provides typical pressure, temperature and mass flow data for a working example of the present invention based on the arrangement shown in Figure 2 .
