Modeling and Simulation of Solar Chimney/Hwt Power Plant for the Assistance of Reverse Osmosis Desalination and Electric Power Generation

Currently the whole world has recognized a very important technical and technological progress, something which has increased the lifespan of human beings, which is one of the results of demographic evolution; it requires meeting the enormous energy and hydraulic needs of the population, especially in areas experiencing water stress. A novel system engineering of Reverse Osmosis (RO) Membrane desalination assisted by solar chimney power plant/horizontal wind turbine (RO/SCPP/HWT) is presented and evaluated. The proposed system is aimed to provide approximately 3500-10,500 m 3 /day of freshwater from seawater (salinity ratio = 40 000 ppm) and about 10 MWe of electricity. The produced freshwater is expected to serve around 55,000~100,000 inhabitants in a semi-arid area in Morocco/ KSA. Horizontal wind turbine and battery bank will be used as a backup source of power during the sun off periods. Two different cases studies that present two different regions are performed in this work (North Africa and Arabian Gulf Regions). The results reveal that the specific power consumption was over 6.181kWh/m 3
