Energy, exergy, and economic analyses of geothermal power generation cycle with different organic fluids

In the present research, energy in geothermal fluid is utilized to generate power. first case of power generation, model double-effect instantaneous evaporation cycle employed, and second one, single-effect combined Rankine with different organic fluids are utilized. The effect several examined. SPECO method has also been applied economic analysis. Given analysis, net generation highest for water vapor lowest a considerable difference. Increasing separator pressure at constant evaporator temperature reduce cost cycles. related operating R113, amount ammonia fluid. Exergoeconomic coefficient, which indicates ratio purchase price components sum costs associated total exergy destruction purchasing components, R113 cycle.
