Mathematical Modeling and simulation of MED without TVC Applied to Zuara Desalination Plant

Abstract

Abstract Mathematical thermodynamic modeling is used in desalination systems to obtain unknown values and predict various properties such as enthalpy or phase equilibrium. These models are useful to understand system behavior. Zuara desalination plant is a multi-effect evaporation plant without vapor pressure (MED) with three total units of 40,000 m3/day. A mathematical modeling of the desalination plant thermal components was performed to simulate and forecast the temperatures, mass flow rates, and the productivity of each cell of steam. The total productivity of the desalination unit and the performance rate in different operating conditions was also found. A Python program was used to solve the model equations. The obtained results show that the productivity of the system and the gain output ratio are directly proportional to seawater temperature and inversely proportional to plant load.
