  • Patent number: 11293414
    Abstract: Systems and methods for generating and a controller for controlling generation of geothermal power in an organic Rankine cycle (ORC) operation to thereby supply electrical power to one or more of in-field operational equipment, a grid power structure, and an energy storage device. In an embodiment, during hydrocarbon production, a temperature of a flow of heated fluid from a source or working fluid may be determined. If the temperature is above a vaporous phase change threshold of the working fluid, heat exchanger valves may be opened to divert flow of heated fluid to heat exchangers to facilitate heat transfer from the flow of wellhead fluid to working fluid through the heat exchangers, thereby to cause the working fluid to change from a liquid to vapor, the vapor to cause a generator to generate electrical power via rotation of an expander.

  • Patent number: 11280323
    Abstract: A geothermal energy system utilizes supercritical CO2 turbine and a radial outflow reaction turbine, a Catherine Wheel having wheel arms, that spins around an axle to produce power. A fin portion extends from the radial portion at an offset angle, to an exhaust end. A first working fluid, such as supercritical carbon dioxide flows through an arm conduit within the wheel arm and a second working fluid, such as a hydrocarbon mixes with the first working fluid and both flow through a turbine. The turbine may be configured within the wheel arm conduit or mounted prior to the Catherine Wheel or any other radial outflow reaction turbine, or variable phase turbines available, and it turns as the combined working fluids expand and vaporize. The second working fluid may be condensed and recirculated while the first working fluid is expelled back into a geothermal reservoir.

    Abstract: A process for cooling a hydrocarbon-rich fraction, in particular natural gas, against a refrigerant circuit. In this process, the compressed refrigerant is divided into three refrigerant substreams. Whereas the first substream is work-producingly expanded in a warm expander and the second substream is work-producingly expanded in a cold expander, the third substream is work-producingly expanded at the lowest temperature level. The result therefrom is that the operating point of the cold expander is shifted in such a manner that the refrigeration output of the two expanders is situated in a ratio between 40/60 and 60/40.

  • Patent number: 9540999
    Abstract: A dual cycle system for generating shaft power using a supercritical fluid and a fossil fuel. The first cycle is an open, air breathing Brayton cycle. The second cycle is a closed, supercritical fluid Brayton cycle. After compression of air in the first cycle, the compressed air flows through a first cross cycle heat exchanger through which the supercritical fluid from the second cycle flows after it has been compressed and then expanded in a turbine. In the first cross cycle heat exchanger, the compressed air is heated and the expanded supercritical fluid is cooled. Prior to expansion in a turbine, the compressed supercritical fluid flows through a second cross cycle heat exchanger through which also flows combustion gas, produced by burning a fossil fuel in the compressed air in the first cycle. In the second cross cycle heat exchanger, the combustion gas is cooled and the compressed supercritical fluid is heated.

  • Patent number: 9458738
    Abstract: Aspects of the disclosure generally provide a heat engine system and a method for regulating a pressure and an amount of a working fluid in a working fluid circuit during a thermodynamic cycle. A mass management system may be employed to regulate the working fluid circulating throughout the working fluid circuit. The mass management systems may have a mass control tank fluidly coupled to the working fluid circuit at one or more strategically-located tie-in points. A heat exchanger coil may be used in conjunction with the mass control tank to regulate the temperature of the fluid within the mass control tank, and thereby determine whether working fluid is either extracted from or injected into the working fluid circuit. Regulating the pressure and amount of working fluid in the working fluid circuit selectively increases or decreases the suction pressure of the pump to increase system efficiency.

  • Patent number: 9322300
    Abstract: Systems, methods, and apparatuses for pressure recovery and power generation may include a pressure recovery generator configured to receive a high-pressure fluid and generate current based on expansion of the high-pressure fluid. The current may be directed to a power electronics module that is configured to receive current from the pressure recovery generator and provide current to a closed-loop thermal cycle, such as an ORC. The current can be used to start components of the closed-loop thermal cycle, such as the pump and/or to black start the turbine generator. In some instances, the current can be combined with current generated by the closed-loop thermal cycle and directed to a utility grid or to external loads. The high-pressure fluid may be directed to heat exchanger components of the closed-loop cycle. For example, high-pressure, high-temperature fluid can be directed to an evaporator, while high-pressure, low-temperature fluid can be directed to a condenser.
