Abstract

The need for electricity has become a basic need for humans. To satisfy the needs of electrical energy, we need power plants and energy sources. The utilization of energy sources must be as efficient as possible, so the application of methods that make the use of energy sources efficient is important. In gas power plants, the application of the inlet cooling method in gas turbine systems is one example. The main purpose of this study is to evaluate the performance of Gas Turbine Cogeneration System at PT Kilang Pertamina Internasional RU III Plaju using energy and exergy analysis at current conditions and after modification, where evaporative cooling will be added. After data processing, it was found that combustion chamber has the largest exergy destruction in both current and modified systems, with values of 26153,45 kW and 25448,87 kW respectively. In the current system, the efficiency of gas turbine system is 24,63%, in HRSG 79,66%, and in cogeneration system is 58,56%. While in the modified system, the efficiency of gas turbine system increased by 0,33% to 24,96%, in HRSG it decreased by 0,39% to 79,27% and an increase of 0,19% occurred in the cogeneration system to 58,75%. The application of evaporative cooling increases the net power produced from 12667,94 kW to 12866,37 kW which means an increase of 198,43 kW or 1,57%. Based on the comparison that has been done, the application of evaporative cooling is quite effective in increasing the net power generated by the system.
