Abstract

The first drilling has successfully completed the drilling of 25 wells. The residual heat of the brine in the Geothermal Power Plant (PLTP) has the potential to be used to generate electricity because it still has a fairly high temperature and pressure. the way to utilize the residual heat of the brine is to use the Organic Rankine Cycle (ORC) which can be used to utilize heat at low temperatures. The abundant geothermal potential is dominated by low enthalpy systems spread throughout Indonesia. The Organic Rankine Cycle (ORC). The main parameters measured are pressure and temperature in the working fluid circulation, hot water circulation (brine), and cooling water circulation. The ORC system uses an evaporator component as a substitute for a generator or boiler system in the Rankine cycle. The ORC system utilizes low temperature heat sources such as Internal Combustion Engine exhaust heat, solar heat, biomass and brine from geothermal plants.. In this study, the authors needed data such as pressure data, temperature data and also mass flow rate data (from flue brine). The location for data collection was carried out in the Sorik Marapi Geothermal field using secondary data. The mass rate value in this study was 13.63 kg/s. where the turbine work is 328.07 Kw and the condenser heat transfer rate is 13.4016 kj/s. which occurs in the Pump work of 311.8544Kw. And the rate of heat transfer in the evaporator that occurs in the where the heat absorbed by the evaporator is 129.6213 kj/s.
