Abstract
Performance improvement in existing single-flash geothermal power plant by applying three cases of expansion design, including double-flash, single-flash combined with the binary, double-flash combined with the binary have been carried out using the thermodynamic method. The Engineering Equation Solver (EES) was employed to solve the mathematical equation in this thermodynamic design. Existing single-flash geothermal plant produces 24,300 kW with first and second law efficiency at 11.75% and 36.7%, respectively. The result shows that the double-flash combined with the binary produce the highest net power output with 30,466 kW. The first and second law efficiencies for this system are 14.73, 46.02 respectively.
