Abstract :In this study, three desalination exergy analysis models including the Cerci et al. model insert ignore into journalissuearticles values(Model A);, Drioli et al. model insert ignore into journalissuearticles values(Model B); and electrolyte solution model insert ignore into journalissuearticles values(Model C);, were developed on an existing reverse osmosis insert ignore into journalissuearticles values(RO); desalination plant in Oman insert ignore into journalissuearticles values(Plant ALG);. A modified ultrapure water insert ignore into journalissuearticles values(UPW); unit fed by Plant ALG has also been proposed insert ignore into journalissuearticles values(Plant A); based on the technology used in a UPW unit operated under the climate of Europe and fed by European river water insert ignore into journalissuearticles values(Plant B);. The most suitable exergy model for characterizing the proposed UPW production plant was used. Model C was found to be the most proper model among its counterparts. It reflected the electrolytic behavior of the relevant streams and considered as the appropriate model. The major exergy destruction sites were also identified, and the exergy efficiency was calculated. The electro-de-ionization insert ignore into journalissuearticles values(EDI); and the RO unit were the highest exergy destructive components in Plant A.
