Patent number: 11959466Abstract: 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.Type: GrantFiled: July 1, 2022Date of Patent: April 16, 2024Assignee: ICE Thermal Harvesting, LLCInventors: Adrian Benjamin Bodishbaugh, Carrie Jeanne Murtland

Patent number: 11912946Abstract: Various embodiments that pertain to fuel processing are described. A fuel processor can produce an endothermic reaction that cools a substance and produces a processed fuel from a raw fuel. A generator can employ the processed fuel to produce an electricity. The generator can supply the electricity to a load that uses the electricity to function. The load can become hot due to its functioning and can benefit from being cooled. The substance cooled by the fuel processor can cool load and in the process the substance can rise in temperature.

Patent number: 11898469Abstract: A reaction turbine operates on the heat released from the condensation of steam, combined with inherent steam pressure and temperature heads. A series of rotors, each containing multiple curved internal channels, provide compressive boosts between successive stages, while avoiding excessive self-compression. Compressive effects and shock waves generated within these channels provide high levels of condensation, thereby releasing immense amounts of heat. The resulting hot vapor and condensate droplets are then ejected tangentially at the periphery of the rotors to generate thrust. The exhaust steam from the last stage is then compressed and returned to the engine inlet to be mixed with the incoming fresh steam, thereby efficiently completing the system cycle without the need of large cooling towers for condensation.Type: GrantFiled: June 2, 2022Date of Patent: February 13, 2024Inventors: Howard Purdum, William F.
