  • Patent number: 8181463
    Abstract: The present invention provides an organic Rankine cycle power system, which comprises means for superheating vaporized organic motive fluid, an organic turbine module coupled to a generator, and a first pipe through which superheated organic motive fluid is supplied to the turbine, wherein the superheating means is a set of coils through which the vaporized organic motive fluid flows and which is in direct heat exchanger relation with waste heat gases.
    Type: Grant

  • Patent number: 5694772
    Abstract: A stream of non-condensable gases that include hydrogen sulfide which are produced by a geothermal plant are disposed of by first compressing at least a part of the stream to form compressed gases. Spent geothermal liquid produced by the power plant is pressurized, and directly contacted with the compressed gases to produce an effluent containing substantially all of the hydrogen sulfide, which can be disposed of in a re-injection well, and a stream of pressurized gases substantially free of hydrogen sulfide which can be released to the atmosphere. Before the stream of pressurized gases are released to the atmosphere, such stream preferably is expanded in a turbine for producing power. Also, preferably, this power so produced is used to compress the non-condensable gases thus reducing the net power consumed. In a further alternative, where chemicals are utilized, almost all of the hydrogen sulfide is stripped from the stream of gases.
