Sustainability of geothermal power plant combined with thermodynamic and silica scaling model

It was found that a double flash system is the best expansion scenario for Dieng Geothermal Power Plant. This scenario produces a high power output of 29,155 kW and the lowest excess deposit of silica at 899 ppm. Although this scenario produces lower power output than the double flash-binary system, it has less negative impact from silica scaling. By introducing this system, the company can obtain additional power output of 4855 kW.
