This paper describes the development of highly flexible calculation methods and computer programs to deal with the complex problems encountered in the design of Mixed Refrigerant Cascade (MRC) plants. The relative merits and operation of the three principal cycles for liquefaction of natural gas, i.e., the expander cycle, the classic cascade cycle, and the MRC cycle, are outlined in the literature[1]. Very little has been published, however, about the detailed process design of these plants, although the capability of a design engineer to produce an optimum solution for a given liquefaction duty is largely dependent on the flexibility and efficiency of the design techniques available to the engineer.
