Abstract
A thermoelectric heat recovery system is described. The thermoelectric heat recovery system includes a thermoelectric generator having a hot side and a cold side. The hot side of the thermoelectric generator is exposed to waste heat emitted by a flare from a well head. The thermoelectric heat recovery system also includes a heat sink coupled to the cold side of the thermoelectric generator. Electricity is generated by a temperature gradient across the thermoelectric generator.
Claims14
A thermoelectric heat recovery system, comprising:
- a thermoelectric generator having a hot side and a cold side, wherein the hot side of the thermoelectric generator is exposed to waste heat emitted by a flare from a well head;
- a heat sink coupled to the cold side of the thermoelectric generator, wherein electricity is generated by a temperature gradient across the thermoelectric generator;
- and
- a power inverter that captures the electricity generated by the temperature gradient across the thermoelectric generator, wherein the power inverter uses electronic circuits to produce alternating current (AC) power that powers local security lighting at a well site including the well head.
