    摘要: An energy recovery, pressure reducing system for reducing high pressure gas in a transmission pipeline to a low pressure gas in a consumer pipeline includes an expander system having at least one expander for expanding the high pressure gas and producing work and low pressure gas that is supplied to the consumer pipeline, and a generator coupled to said expander for converting the work to electricity which is supplied to an electrical load. The system further includes apparatus including an on/off valve serially connected to a pressure regulating valve, the apparatus being connected in parallel with the expander system. The on/off valve has an open state for effecting transmission of gas through the pressure regulating valve which has an adjustable flow control opening for throttling high pressure gas and producing low pressure gas when the on/off valve is in its open state; and a closed state for preventing transmission of gas through the pressure regulating valve. A control system is provided which is responsive to flow through the expander system for controlling the size of the flow control opening and the state of the on/off valve.

    摘要: 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.
