An apparatus for producing power from a geothermal fluid that is a mixture of high pressure steam and brine comprising a separator, a steam turbine coupled to a generator, a steam condenser, the vaporized organic fluid is supplied to a superheater, an organic vapor turbine coupled to a generator, an organic vapor condenser. The apparatus further comprises a preheater which preheats the organic condensate and produces a stream of pre-heated organic fluid that is supplied to the steam condenser as well as a stream of cooled steam condensate. A recuperator is provided for transferring heat from the heat depleted organic fluid produced by the organic vapor turbine to organic condensate produced by the organic vapor condenser. The heated organic condensate produced by the recuperator is supplied to the preheater while cooled, heat depleted organic vapor produced by the recuperator is supplied to the organic vapor condenser. The stream of cooled brine is combined with the stream of cooled steam condensate to form a combined stream of diluted cooled brine that is less susceptible to precipitation of minerals.
