Abstract: The aim of this paper is to modeling and simulation a multi-effect desalination system with thermal vapor compression (MED-TVC) under a steady state condition. A mathematical model of MED-TVC system is developed based on mass and energy balances also the thermodynamics seawater properties. An economic model is developed to estimate the cost of produced water ($/m3). The proposed models using to minimizing the total annualized cost of the desalination unit. This work proposed a combination between Matlab and the process simulator Aspen HYSYS to solve the problem. A commercial unit installed in the Tunisian Chemical Group (GCT) factory presented as a case study to validate the proposed model. Good agreement is obtained between the simulation results and the industrial data.
