A method for using a two-phase fluid includes separating the fluid into its two phases, one of which is a hot gas containing energy in the form of latent heat, and one of which is a hot liquid containing energy in the form of sensible heat; converting sensible heat in the liquid to sensible heat in a working fluid for producing preheated working fluid; and transferring latent heat in the gas to the preheated working fluid for vaporizing the same at substantially constant temperature and pressure.

[ We claim:] [1.] A power plant comprising:a) a separator for separating a two-phase geothermal fluid into a vapor stream containing steam, and a liquid stream containing hot brine;b) a steam turbine associated with a generator and responsive to said steam for driving the generator and producing power and expanded steam;c) a steam condenser containing an organic fluid for condensing said expanded steam and producing steam condensate and vaporized organic fluid;d) an organic vapor turbine associated with a generator for driving the generator and producing power and expanded organic vapor;e) an organic fluid condenser for condensing said expanded organic vapor and returning the resulting condensate to said steam condenser;f) a preheater interposed between the organic condenser and said steam condenser for preheating said resulting condensate before it is returned to said steam condenser; andg) means for applying said steam condensate to said preheater for preheating said resulting condensate before it is returned to said steam condenser.
