2.3 Effect of Turbine, Pump, Pinch Condenser, and Evaporator Efficiency on SORC System Economic Indicators  
Figure 7 shows the effect of turbine and pump efficiency on the system indicators, where an increase in turbine efficiency, as shown in Figure 7a-c, causes a decrease in the three system indicators considered in the study. The LCOE decreases by 21.1%, the SIC by 21.7%, and the PBP by 21.2% for the three working fluids, which evidences that the efficiency of the turbine in the range of study has a positive impact on lower values of the economic indicators of the system, with acetone being the fluid that presents better results in comparison to toluene and cyclohexane. On the other hand, the efficiency of the pump did not significantly affect the economic indicators, as shown in Figure 7d-f. In this case, the economic indicators did not show a decrease greater than 1%. However, it is important to consider that although the efficiency of the pump does not exert any significant variation on the economic indicators, they tend to take lower values than those obtained when varying the efficiency of the turbine. In this sense, when the efficiency is 90% for both the pump and the turbine using toluene as the working fluid, LCOE values of 0.1132 USD/kWh and 0.1470 USD/kWh, respectively, are obtained. Therefore, it is necessary to perform multi-objective studies to determine the optimal values of the variables of studies to maximize energy indicators by decreasing the economic indicators of the system.

Figure 8 shows the effect of the increase in evaporator pinch temperature on the values of the system's economic indicators, using toluene, acetone, and cyclohexane as the working fluid. The results show that the increase in the three economic indicators does not exceed 2.5% for toluene and cyclohexane, while for acetone they were below 1% as shown in Figure 8a-c. In addition, the temperature of the condenser pinch also influences an increase in the indications of the system as shown in Figure 8d-f, where the LCOE showed an increase of 16.10% (toluene), 3.64% (acetone), and 5.86% (cyclohexane). Similar behavior was found in the SIC and PBP where their output values showed percentages of increase similar to those reported in the LCOE, which is because these indicators are calculated from the same variables of cost-effectiveness of the system.
