This study aims to conduct a thermodynamic analysis of desalination system integrated with combined cycle power plant (CCPP), with a focus on the throttling process method combined with a steam compressor, the influence of pinch point temperature difference (PPTD) on distilled water production (specific aquadest production/SAP) and specific energy consumption (SEC). Reducing condenser pressure from 10.89 to 8.43 kPa and PPTD of 10 can increase steam turbine power by 2.18% and allow the wastewater temperature to drop to 32.5 degrees C. At a throttle valve pressure of 2.65 kPa and a mass release of water into the sea of 99.5%, steam can be condensed into distilled water with a SEC value of -1,423.36 kJ/kg with a SAP value of 3.63 kg/s under optimal conditions. In addition, a lower PPTD allows the condenser to convert vapour into liquid more efficiently due to the smaller temperature difference, resulting in more effective heat transfer.
