Özet
This study investigates the thermodynamic and economic aspects of a multigeneration plant for inherent production of freshwater, power, cooling and heating by utilizing geothermal energy. The developed plant utilizes geothermal energy at a target temperature of 200 degrees C through a single flash-binary power plant with reinjection. The results of the thermodynamic analysis show that the overall plant energy and exergy efficiency of the plant can be as high as 61 % and 37.8 %, respectively, while the plant cost varies between 160-330 $/h. Optimization results show that an optimal exergy efficiency of 58 % is achievable when the plant cost rate is 242 $/h. The results indicate that geothermal driven freshwater production is one of the most economically feasible renewable driven clean production options, while a flash/binary power plant results in higher efficiency and lower electricity costs.
