  • the increased number of heat exchanger types causes increased engineering costs.
  • the embodiment of the method according to the invention for liquefying a hydrocarbon-rich stream shown in FIG. 5 differs from that shown in FIG. 4 only in that the refrigerant mixture of the second mixed refrigerant cycle is vaporized at two different temperature levels.
  • the heat exchanger E5 shown in Figure 4 is divided into two heat exchangers E5A and E5B.
