Abstract

to analyze the GPP system using exergoeconomic analysis by incorporating the Kalina cycle KCS-11 to utilize the waste heat from the Lumut Balai GPP in Muara Enim. The analyzed components include the heat exchanger, steam turbine, high-temperature recuperator, low-temperature recuperator, condensate pump, drain tank, and condenser. The study assumes an environmental temperature of 30°C, 85% ammonia concentration, and a pressure of 35 bar. The costs associated with the investment, operation, and maintenance of these components are based on literature values. Cycle Tempo 5.0 and Diagram from literature for designing the flowsheet and obtaining fluid properties. The analysis reveals the highest exergy destruction rate occurs the condenser and heat exchanger 1, with values of 26,831.34 kW and 23,160.79 kW at an environmental temperature of 30°C. The lowest exergy efficiency is also observed in the condenser and heat exchanger 1, with values of 1.90% and 28.43%. Exergoeconomic analysis indicates that the condenser incurs the highest exergy destruction cost at 2,223.762 USD/h at an environmental temperature of 30°C, corresponding directly to the magnitude of exergy destruction within the condenser. From the perspective of the cost effectiveness of investment, operation, and machine maintenance, known as the f-factor, lowest value is found in the LT Recuperator and condenser at 1.78% and 5.52%, followed by HE 2 with a value of 1.49%
