碩士 / 淡江大學 / 化學工程與材料工程學系碩士班 / 102 / The objective of this research is to combine renewable solar thermal energy and seawater membrane distillation desalination systems into green processes. The units of the systems include air gap (AGMD), direct contact (DCMD) and vacuum membrane distillation (VMD) modules. In order to assess the economic design point of the process, the Aspen Custom Modeler (ACM) was used to build the mathematical model to describe each unit of solar-driven membrane distillation desalination systems. Simulation results show that the total annual costs (TAC) of air gap (AGMD), direct contact (DCMD) and vacuum membrane distillation (VMD) modules for 2000 kg/hr water production are $57,092, $123,411 and $350,565, respectively. The control structures of solar-driven membrane distillation desalination systems were built which include quality control in order to maintain the water production rate and day/night operating mode. Finally, the dynamic simulations of these systems in all seasons are demonstrated to validate the operability analysis results. The optimal unit water production costs of air gap (AGMD), direct contact (DCMD) and vacuum membrane distillation (VMD) modules are $2.7/m3, $5.4/m3 and $10.4/ m3, respectively.
