Booshli (sabalan) in northwestern Iran is one of the regions with the most geothermal potential. In the present study, single, double, and triple flash cycles for producing power from Booshli’s geothermal well have been investigated. Then, the presented cycles have been analyzed from energy, exergy, and economic viewpoints. Furthermore, with different single-objective approaches (energy efficiency, exergy efficiency, and power specific cost) and multi-objective approaches, are optimized relative to their separator's Pressure, respectively. Moreover, a parametric study has been carried out on the separator’s pressure to establish the effect on performance parameters for each cycle. It has been revealed that triple flash has a better performance compared to single and double flash cycles for power production from Booshli's geothermal well, both in thermodynamics and economic aspects. The results show that for a triple flash cycle in multi-objective optimum condition (at pressure 1351 kPa for the first, 440.9 kPa for the second, and 80.09 kPa for the third separator), the net output power, energy efficiency, exergy efficiency, exergoeconomic factor, and the power specific cost rate were calculated to be 8463 kW, 15.24%, 57.01, 79.7% and 4.853 $/GJ, respectively.
