  • Solar thermal power generation using multiple working fluids in a rankine cycle
    Patent number: 9074585
    Abstract: A system to convert the heat collected by solar thermal collectors into electricity using a Rankine cycle generator with multiple working fluids and multiple temperature-level heat sources is disclosed.
    Type: Grant
    Filed: August 19, 2009
    Date of Patent: July 7, 2015
    Assignee: TAS Energy, Inc.

  • Process utilizing high performance air-cooled combined cycle power plant with dual working fluid bottoming cycle and integrated capacity control
    Patent number: 9057288
    Abstract: A combined cycle power plant system and methods of operation so as to minimize consumption of cooling water utilizes exhaust from a combustion turbine to generate steam for power generation in a steam turbine topping cycle. The exhaust steam from the steam turbine topping cycle is utilized to vaporize an organic working fluid in an organic working fluid bottoming cycle, where vaporized organic working fluid expanded across a turbine generates additional power. Exhaust gas from the organic working fluid bottoming cycle is condensed utilizing an air-cooled heat exchanger. Heat exchange bundles of the air-cooled heat exchanger are preferably arranged horizontally relative to the ground to maximize efficiency. Turbine inlet cooling is employed at the combustion turbine to recapture energy lost in the system. A thermal energy storage tank may be utilized in conjunction with the turbine inlet cooling to supply chilling water to the system.
