A method for producing power from geothermal fluid includes: separating the geothermal fluid in a flash tank into geothermal steam and non-condensable gases, and geothermal brine; supplying the geothermal vapor to a vaporizer; vaporizing a preheated motive fluid in the vaporizer using heat from the geothermal steam to produce geothermal steam condensate and vaporized motive fluid, wherein-the heat content in the geothermal steam exiting the flash tank is only enough to vaporize the preheated motive fluid in the vaporizer; expanding the vaporized motive fluid in a vapor turbine producing power and expanded vaporized motive fluid; condensing the expanded vaporized motive fluid in a condenser to produce condensed motive fluid; and preheating the condensed motive fluid in a preheater using heat from the geothermal steam condensate and the geothermal brine, thereby producing the preheated motive fluid, make¬ up water and heat-depleted geothermal brine. |
