This paper describes a model which simulates the dynamics of a multi-effect distillation system in different operating conditions. It have been designed to improve the operation of the process and develop a control strategy which optimise the distillate production. The physical models are based on mass; energy and salt conservation equations and experimental correlations for heat transfer. Conservation laws are applied in the different components such as the heater; the effects and preheaters. The results of the mathematical model of the whole process show promising results.
