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.

Methods and systems for generating power (and optionally heat) from a high value heat source using a plurality of circulating loops comprising a primary heat transfer loop, several power cycle loops and an intermediate heat transfer loop that transfers heat from the high-temperature heat transfer loop to the several power cycle loops. The intermediate heat transfer loop is arranged to eliminate to the extent practical the shell and tube heat exchangers especially those heat exchangers that have a very large pressure difference between the tube side and shell side, to eliminate shell and tube, plate type, double pipe and similar heat exchangers that transfer heat directly from the primary heat transfer loop to the several power cycle loops with very high differential pressures and to maximize the use of heat transfer coils similar in design as are used in a heat recovery steam generator commonly used to transfer heat from gas turbine flue gas to steam or other power cycle fluids as part of a combined cycle power plant.

In the present invention, a recuperator is used in a refrigerant cycle to make a heat exchange between a refrigerant generated in a condenser and a refrigerant before flowing into a compressor, thereby supercooling the refrigerant to minimize the quality of the refrigerant introduced into an evaporator, elevating temperatures at an inlet and an outlet of the compressor, and increasing condensed heat of the condenser. In the present invention, a recuperator is used to increase condensed heat of the condenser, leading to increasing the heat which circulation water circulating in a steam producing cycle receives from the condenser, whereby steam production efficiency can be improved.

A system for generating steam for industrial heat. The system may include a plurality of heat pump cycles in thermal communication with each other and in thermal communication with a steam generation cycle. The plurality of heat pump cycles may include first and second heat pump cycles. The first heat pump circulates a first a working fluid and includes a first heat exchanger. The second heat pump cycle circulates a second working fluid and includes a second heat exchanger. The first heat exchanger transfers heat from the first to the second working fluid. The second heat exchanger transfers heat to a third working fluid in the steam generation cycle.
