Summary

Industrial energy consumption is extremely high. Thermal power plants contribute to approximately 40% of total water withdrawal in the US but dissipate a large amount of vapor and heat energy. Transport membrane condensers have been demonstrated to have great potential to recovery waste heat and water as a combination of membrane condensers and heat exchangers. In this study, a laboratory membrane heat exchanger system was developed using plate ceramic membrane and hollow fibers. The heat and water recovery performances were studied to estimate the heat and mass transfer characteristics of membrane heat exchangers. The operating conditions show significant effects on the recovery performances of system. A computational fluid dynamics (CFD) model was developed using experimental data to consider the heat and mass transfer. The simulation model shows great agreements with experimental results. The temperature distribution as well as vapor mass fraction were analyzed to have an insight about the condensation and mass transfer of water vapor.
