Claim 0:
1. A system to generate power in an organic Rankine cycle (ORC) operation, the system comprising:
at least one ORC unit configured to generate electrical power; and
at least one mobile heat generation unit in fluid communication with the at least one ORC unit and configured to operate with one or more heat sources, including at least a wellhead fluid source, supplying a high pressure or high temperature fluid to the at least one mobile heat generation unit, the at least one mobile heat generation unit configured as a transportable module and including:
a frame having a chamber therein,
at least one heat exchanger mounted within the chamber and configured to connect to at least one of the one or more heat sources,
one or more valves positioned between the at least one heat exchanger and the at least one of the one or more heat sources,
a fluid recirculation system at least partially located within the chamber and comprising:
a fluid intake conduit coupled to a return line in fluid communication with the at least one ORC unit to receive a working fluid,
a fluid outlet conduit configured to couple to a heated fluid supply line in fluid communication with the at least one ORC unit to supply the working fluid thereto,
a pump connected to the fluid intake conduit and configured to pump the working fluid received through the fluid intake conduit, and
a piping array including (a) a first section of piping extending between the pump and the at least one heat exchanger to supply the working fluid to the at least one heat exchanger, and (b) a second section of piping extending between the at least one heat exchanger and the fluid outlet conduit, so that as the working fluid passes along the piping array and through the at least one heat exchanger, heat from the high pressure or high temperature fluid supplied to the at least one heat exchanger from the one or more heat sources transfers to the working fluid so as to heat the working fluid, and

a controller connected to the frame and having programming configured to:
monitor a pressure of the high pressure or high temperature fluid upstream of the one or more valves and to actuate the one or more valves to enable flow therethrough in response to the pressure of the high pressure or high temperature fluid being below a threshold, and
monitor temperature, pressure, or a combination thereof of the working fluid passing along a fluid recirculation loop defined between the mobile heat generation unit and the at least one ORC unit and to regulate flow of the working fluid through the at least one heat exchanger for transfer of heat from the flow of the high pressure or high temperature fluid to the working fluid for supply to the at least one ORC unit.
