  • performance improvement of a single flash geothermal power plant in dieng indonesia upon conversion to a double flash system using thermodynamic analysis
    Renewable Energy, 2015
    Co-Authors: Nugroho Agung Pambudi, Saeid Jalilinasrabady, Ryuichi Itoi, Khasani Jaelani
    Abstract:

    We investigated proposed design of a double-flash system and compared it to the existing single-flash power plant in Dieng, Indonesia, which uses waste brine from a high Pressure Separator. The performance of the double-flash system was evaluated using the second law of thermodynamics, and this was based on energy and exergy analyses. The Engineering Equation Solver (EES) was used to solve the relevant mathematical equations.

The performance of the double-flash system was evaluated using the second law of thermodynamics, and this was based on energy and exergy analyses. The Engineering Equation Solver (EES) was used to solve the relevant mathematical equations.Our results indicate that the double-flash design is interesting for application in Dieng since the power output would increase by 19.97%. Moreover, the precipitation system to avoid silica deposition in the injection well does not have to change much. Therefore, the building costs associated with the new double-flash system would be minimal. The available exergy from the reservoir is 66,204kW based on the enthalpy determined by TFT (Tracer Flow Test) measurements. The single-flash power plant has a net power output of 23,400kW with a second law efficiency of 36.7%. In the double-flash design, components such as a LPS, a second purifier and an HPT would be added to the plant. Furthermore, our calculations indicate that the power plant's output and second law efficiency would increase to 29,155kW and 44.04%, respectively. The waste brine disposed of using this precipitation system would decrease by 8.22% at 5443kW.

  • exergoeconomic analysis of a novel integrated transcritical co2 and kalina 11 cycles from sabalan geothermal power plant
    Energy Conversion and Management, 2019
    Co-Authors: Mehran Abdolalipouradl, Shahram Khalilarya, Samad Jafarmadar
    Abstract:

    Abstract A new integrated cycle based on different real temperatures and Pressures on Sabalan geothermal power plant, located in Iran, has been proposed and thermodynamic and exergoeconomic analyses are performed. The Kalina and Transcritical Rankine cycles are used as bottoming cycles and an algorithm are applied to find the exact location of the pinch points in heat exchangers. Also, a parametric study carried out to reveal the effects on the thermodynamic and exergoeconomic performance of the integrated cycle of such important parameters as Separator 1 Pressure, Separator 2 Pressure, pinch point temperature difference in the evaporators, higher Pressure of the Kalina cycle and the ratio of the Transcritical cycle higher Pressure to the critical Pressure. Finally, the proposed cycle performance is optimized from the thermodynamic and exergoeconomic viewpoints. The results show that for the integrated geothermal power plant, the power generation, thermal efficiency, exergy efficiency and power specific cost rate are calculated to be 19,448 kW, 16.63%, 63.78%, and 4.521 $/GJ, respectively, which indicate that the proposed cycle has improved thermodynamically and exergoeconomically compared to previous studies.
