Dynamic modeling and simulation of a multi-effect distillation plant

Abstract

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

Dynamic modeling and simulation of a solar-assisted multi-effect distillation plant

“…Kishore et al [12] presented a work-in-progress simulator for the steady state and the dynamics of a multi-effect distillation mechanical vapor compression (MED-VC) desalination system, showing a dynamic simulation of a single effect. Roca et al [13] developed a dynamic model of a multieffect distillation plant based on the heat transfer correlations presented in [14]. This model is an improved version of a previous one in which the heat transfer coefficients were considered constants [15].…”
