Thermal analysis of the mechanical vapour compression system is presented. The effects of the operating parameters (e.g. evaporator temperature, pressure drop across the evaporator, feed temperature to the evaporator, etc.) on the work done, compressor size, heat transfer areas of the evaporator and the multiflow heat exchanger are studied. A new expression, the available energy consumption per unit amount of distillate, is defined. This expression enables rational comparison of the vapour compression energy consumption with that of other desalting systems. The potentiality of reducing energy consumption by combining the vapour compression system with other desalting system (e.g. multistage or multieffect systems) is illustrated by an example.
