The KCS converts the thermal energy from the waste brine discharged to the earth crust as a heat source. Based on the brine temperature condition, KCS 11 is the most suitable system among others owing to excellent performance at low to mid-regime temperatures. The constraints of the investigation are focused on the consideration of minimum silica saturation index (SSI) standard of the brine, owing to high SiO2 content. The system is optimized based on the most optimum ammonia-water mass ratio of the working fluid. The system can generate 1660.30 kW of electricity from 48 kg/s of unused brine with 13.20% thermal efficiency while maintaining the proper SSI standard. Owing to the nearly zero cost of heat production from the brine, this system can support the electrification of Wayang Windu geothermal power plant.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]The authors express their great appreciation to Star Energy Geothermal Wayang Windu Ltd. for assistance in providing data required for this study.
