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.

Method and means for using a two phase fluid

Power is produced from high presser geothermal fluid by separating the fluid into high pressure steam and high pressure brine, expanding the high pressure steam in a high pressure turbogenerator for producing power and heat depleted steam, and separating liquid from the heat depleted steam thereby producing dried heat depleted steam at a pressure and temperature lower than the pressure and temperature of the high pressure steam. The liquid so separated, and the high pressure brine are combined in a flash chamber which produces steam which is combined with the dried heat depleted steam and expanded in a lower pressure turbogenerator for producing additional power. Optionally, some of the high pressure steam is used to reheat the dried heat depleted steam and the steam produced by the flash chamber before such steam is expanded in the lower pressure turbogenerator.

Method of and means for using a two phase fluid

A Rankine cycle power plant includes a pair of multistage turbine modules each of which has an input for receiving vaporized working fluid and an output shaft, and each of which is responsive to vaporized working fluid applied to its input for expanding the working fluid and producing work at the output shaft and heat depleted working fluid that is superheated. An electrical generator is located between the modules and directly coupled to their output shafts. Superheated, heat depleted working fluid from one of the modules is supplied to the input of the other of the modules.
