| Description: |
This work develops novel tools for the multi-period and multiscale synthesis of water desalination systems for systematically optimizing the benefits of the integration of emerging desalination technologies and the water-energy nexus. The research develops the optimization frameworks for the following problems: (1) optimization of multi-effect distillation (MED) design via MD brine treatment and process heat integration, (2) synthesis of desalination systems for multi-period capacity planning, and (3) synthesis and scheduling of solar-assisted membrane distillation (MD) for domestic water desalination. To solve the three problems, the water-energy nexus must be addressed in the planning, design, and operation of the water desalination system. In the first problem, an optimization approach to the design of MED-MD in the context of water-energy nexus with an industrial process is developed. The hybrid MED-MD desalination system is thermally integrated with industrial facility while any additional required thermal energy is supplied from external sources. The optimization framework targets optimizing the operating and design variables of the MED and MD units as well as the excess heat extracted from the industrial facility. In the second problem, an optimization approach was used to identify the optimal capacity planning of distressed water desalination systems considering the integration of emerging desalination technologies. Despite the economic challenges many emerging technologies face, some new desalination technologies such as MD demonstrate promising candidacy in the optimal expansion of desalination systems due to their modularity and other advantages. The developed framework also addresses the multiscale nature of the problem. Unit-specific decision variables such as the top brine temperature (TBT) and MD recycle ratio are simultaneously optimized with the synthesis of the multi-period flowsheet. In the third problem, a systematic approach for the design and scheduling of a skid-mounted solar-assisted ... |
