Classification: CPC F  E  H  Y | IPC E  F  H

Claim 0:
1. A system to generate electrical power, the system comprising:
a first valve positioned to divert wellhead fluid from a wellhead;
a heat exchanger including (a) a first fluid path to receive the wellhead fluid from the valve and (b) a second fluid path to receive a working fluid, the heat exchanger positioned to transfer heat from the wellhead fluid to the working fluid;
a recycle unit, including a generator, a condenser, and a pump, positioned so that a flow of the working fluid from the second fluid path causes the generator to generate electrical power during operation when the condenser is positioned to cool the working fluid of the heat exchanger and the pump is positioned to transport the working fluid from the condenser toward the second fluid path of the heat exchanger;
a second valve operatively positioned to reduce a pressure and temperature of the wellhead fluid from the heat exchanger; and
a third valve positioned to divert at least some of wellhead fluid from the first valve to the condenser.
