1. A system to generate electrical power, the system comprising:
a 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, a flow of the working fluid from the second fluid path to cause the generator to generate electrical power, the condenser positioned to cool the working fluid downstream of the heat exchanger, and the pump positioned to transport the working fluid from the condenser toward the second fluid path of the heat exchanger;
a choke valve operatively positioned to reduce a pressure and temperature of the wellhead fluid from the heat exchanger; and
a condenser valve to divert at least some of wellhead fluid from the choke valve to the condenser.
