Abstract: A hydrocarbon flow control generator system includes a pressurized hydrocarbon flow inlet, an expansion device in pressurized hydrocarbon flow communication with the pressurized hydrocarbon flow inlet, a generator connected to the expansion device, a drive system connecting the generator and the expansion device, a gathering point at which depressurized hydrocarbon stream is delivered to an end use location, and a variable load device via which an electrical power stream generated by the generator is delivered to an electric load. The expansion device is configured to receive a highly pressurized hydrocarbon stream from the pressurized hydrocarbon flow inlet, control and regulate a received hydrocarbon stream, and depressurize the hydrocarbon stream. The variable load device is configured to adjust load on the generator by adjusting electrical demand on the generator based on a pressure of the depressurized hydrocarbon stream sensed between the expansion device and the gathering point.

Abstract: Systems and methods for generating and a controller for controlling generation of geothermal power in an organic Rankine cycle (ORC) operation in the vicinity of a wellhead during hydrocarbon production 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 wellhead fluid from the wellhead 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 wellhead 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.
