Increasing global demand for fresh water is driving research and development of advanced desalination technologies. As a result, a detailed model of multiple e ect distillation (MED) is developed that is exible, simple to implement, and suitable for use in optimization of water and power cogeneration systems. The MED system is modeled in a modular method in which each of the subcomponents is modeled individually and then instantiated as necessary in order to piece together the complete plant model. Modular development allows for studying various MED con gurations (such as forward feed, parallel feed, etc.) with minimal code duplication. Through a parametric analysis, it is found that the present model compares very well with the simple model provided by El-Sayed and Silver while providing substantially more detail in regards to the various temperature pro les within the MED system. Further, the model is easier to implement than the detailed El-Dessouky model while relying on fewer assumptions.The increased detail of the model allows for proper sensitivities to key variables related to input, operating, and design conditions necessary for use in a cogeneration or hybrid system optimization process.

“…On the other hand, limited studies were published handling ME-TVC desalination system from exergy (Second Law) point of view since the middle of last decade, but it has been carried out in several published works recently. (Hamed et al, 1996) conducted and evaluated the performance of a ME-TVC desalination system. An exergy analysis was also performed and compared with conventional multi effect boiling (MEB) and mechanical vapor compression (MVC) desalination systems.…”

“…In these analyses, different models have been adopted to estimate the thermodynamic properties of seawater. Frequently, seawater has been represented by aqueous sodium chloride solutions of equivalent salt content or salinity [1][2][3]. 3 Although sodium chloride is the major constituent in seawater, such matching does not bring all important properties of the two solutions into agreement [4].…”

Exergy analysis is a powerful diagnostic tool in thermal systems performance evaluation.The use of such an analysis in seawater desalination processes is of growing importance to determine the sites of the highest irreversible losses. In the literature, exergy analyses of seawater desalination systems have sometimes modeled seawater as sodium chloride solutions of equivalent salt content or salinity; however, such matching does not bring all important properties of the two solutions into agreement. Furthermore, a common model that represents seawater as an ideal mixture of liquid water and solid sodium chloride may have serious shortcomings. Therefore, in this paper, the most up-to-date thermodynamic properties of seawater, as needed to conduct an exergy analysis, are given as correlations and tabulated data. The effect of the system properties as well as the environment dead state on the exergy and flow exergy variation is investigated. In addition, an exergy analysis for a large MSF distillation plant is performed using plant operating data and results previously published using the above-mentioned ideal mixture model. It is demonstrated that this ideal mixture model gives flow exergy values that are far from the correct ones. Moreover, the second law efficiency differs by about 80% for some cases.
