Rising water scarcity and abundant brine water resources, especially in desert locations, call for the wider adaptation of desalination techniques. Furthermore, the interdependency of water and energy has gained more attention in recent years and it is expected to play an important role in the near future. The present study deals with both topics in that it presents the coupling of a power plant with desalination units for the simultaneous generation of energy and water in Iran. The power plant used in the analysis is the Qom combined-cycle power plant. The plant is integrated, first, with a multi-stage flash (MSF) unit and, then, with a multi-effect desalination (MED) unit, and it is evaluated using energy and exergy analyses. We find that the generated power of the integrated systems is decreased by 9.7% and 8.5% with the MED and the MSF units, respectively. Lastly, the freshwater production in the plant using MED is significantly higher than in the plant with MSF (1,000 versus 1,521 kg/s).

日益严重的缺水和丰富的盐水资源，特别是在沙漠地区，要求更广泛地应用淡化技术。此外，近年来，水和能源的相互依存关系受到更多关注，并且有望在不久的将来发挥重要作用。本研究涉及这两个主题，因为它介绍了发电厂与海水淡化装置的耦合，以同时在伊朗生产能源和水。分析中使用的电厂是Qom联合循环电厂。该工厂首先与多级闪蒸（MSF）单元集成在一起，然后与多效脱盐（MED）单元集成在一起，并使用能量和火用分析对其进行评估。我们发现，使用MED和MSF装置，集成系统的发电量分别降低了9.7％和8.5％，分别。最后，使用MED的工厂中的淡水产量显着高于使用MSF的工厂中的淡水产量（1,000对1,521 kg / s）。
