“…The waste heat of flue gases can be used to improve the performance of combined cycle power plants, according to numerous studies [21,22]. Although the process benefits of the power cycle have been established, no careful use of flue gas heat to enhance the performance of thermal desalination has been thoroughly researched.…”

Access to clean water and sanitation is one of the Sustainable Development Goals (SDGs), a global action plan agreed upon by world leaders. Water demand is increasing every year. As much as 97% of the water on earth is seawater, which requires desalination technology to convert seawater into freshwater that will be used to meet daily human needs. It is necessary to continue to develop environmentally friendly clean water treatment technology to overcome the problem of freshwater crisis. Research related to clean water treatment technology needs improvement in order to have a high effectiveness value to be applied and developed in areas with clean water crisis. Therefore, this study aims to produce distilled water by utilizing heat from the condenser of a steam power plant. The cooling water from the condenser must first be throttled to allow the vapor and liquid extraction to occur. Next, the steam is compressed to raise the temperature. After the compression process, the steam must be condensed using a water-cooled condenser to produce the distilled water in order to get maximum distilled water yields and low energy consumption. In this study, the lowest SEC (Specific Energy Consumption) was -1194.02kJ/kg of distilled water with the mass flow rate of 0.996 kg/s. To overcome the environmental problems, the condenser temperature was lowered to 41.5°C, and the PPTD (Pinch Point Temperature Difference) by 10 made the temperature discharge to seawater drop to 31.5°C. The lowest energy consumption can be obtained by setting the temperature in the cyclone separator to 22°C and the mass of water discharged to the sea by 99%, which lowers compressor energy consumption.

The problem of freshwater is an issue that has been hot for discussion for decades. The number of industries and the increasing population in the world has caused the need for clean water to increase drastically. This scarcity occurs because 97.7% of the water available on earth contains salt. Only 2.3% contains no salt, and 99.5% of the amount is ice, groundwater, and the atmosphere. With a large percentage of seawater, water needs for human survival can be met by using the desalination method. In this study using a throttling valve and utilizing cold water (secondary product) as a refrigerant to cool the room. This research will also discuss how specific energy consumption and cooling heat are affected by compressor pressure and cyclone pressure to prove how capable and efficient the renewable desalination method is in producing aquadest water, which is expected to help water availability to meet water needs. The simulation results obtained The optimum value of the system specific energy consumption is 287.90 kJ / kg with a compressor pressure value of 10 kPa and a cyclone temperature value of 4 ° C. The optimal value of system cooling heat is 51.01 kW with a compressor pressure value. At 10 kPa and a cyclone temperature value of 2 ° C. The effect of the cooling heat value significantly affects the specific energy consumption required for this system.
