In northwestern Iran, two wells with different temperature and pressure conditions have been exploited in Sabalan region. According to the thermodynamic properties of wells, the combined cycle (flash combined cycle with transcritical CO2 and Kalina 11) is proposed for Sabalan geothermal. In the Kalina 11 and transcritical CO2 heat exchangers, in which the fluid temperature is rising, there is a different temperature variation gradient, therefore, a new method is proposed for the determination of pinch point and other thermodynamic properties. The effects of the Kalina high pressure, amoina concentration, transcritical CO2 cycle pressure ratio, pinch points temperature difference and separators’ pressure on the thermal and exergy efficiencies of the proposed combined cycle were studied, Finally the proposed combined cycle was optimized thermodynamically using the EES (Engineering Equation Solver) software. Based on identical operation conditions, the net power of the combined cycle is 20046 kW, the thermal efficiency is 17.15%, the rate of exergy destructions is 8259 kW and the exergy efficiency is 65.74%. It was found that the net power output, the thermal and exergy efficiencies of combined cycle are about 17.55%, 17.55% and 18.35% higher than the previously proposed system.
