| Abstract |
After separation process in a separator, two phase geothermal fluids will produce steam and brine. Power plant will produce condensate as side products. Normally, the condensate is injected through reinjection wells in order to maintain sustainability of fluids in the reservoir. In certain case, brine and condensate temporarily are collected in cooling pond before pumped into reinjection wells. If the flow rates of the brine and the condensate are high with relatively high of potential head too, the fluids contain significant energy that can be utilized using small unit power plant. Small unit power plant with brine can be used to generate one phase power that can be used as own use. This study was aimed to assess power potential that can be generated using brine and condensate at a field owned by PT. Pertamina Geothermal Energy. The assessment will be used for further small unit turbine design and power supply. The calculation and the analyses data from a geothermal field show the capacity of 5 KW using small unit turbine with Banki type and generator rotation of 1500 rpm. |
