Solar heating for site located oil storage or separation
A system for providing supplemental or auxiliary heat to a crude oil separator is provided. The system includes a primary circuit carrying a fluid heated by a solar panel and a secondary circuit carrying a fluid heated by heat exchangers engaged with the primary circuit. The secondary circuit includes heat exchangers engaging the separator to provide auxiliary heat. The system may also include a source of off-grid electrical energy, such as a wind turbine and/or photoelectric cell.
1. A device for heating product at an oil well site to assist the separation or the maintenance of separation of the oil product into at least clean oil, water, and gas components, the device comprising:
a heater treater including a housing, the housing defining a heater treater interior, the heater treater including a fire tube access opening, the heater treater adapted to receive oil well product in the interior thereof;
a primary circuit, the primary circuit including a solar panel, a first non-water, liquid heat transfer medium chosen to maintain a liquid state in the circuit, and a primary/secondary circuit heat exchanger, a primary circuit pump, and a first fluid flow pathway, the pump for engaging the first fluid flow pathway for circulating the first non-water, liquid heat transfer medium between the solar panel and the primary/secondary circuit heat exchanger;
a secondary circuit comprising a buffer tank adapted to receive the primary/secondary heat exchanger, a second non-water, liquid heat transfer medium, a secondary circuit pump adapted to pump the second heat non-water, liquid transfer medium chosen to maintain a liquid state in the circuit therethrough, an outlet pipe engaging the buffer tank, and an inlet pipe engaging the buffer tank;
an assembly engaging the fire tube access opening with the secondary circuit for heating the oil product within the heater treater;
wherein the secondary circuit pump circulates the second heat transfer medium through the buffer tank, the outlet pipe, and the assembly engaging the fire tube access opening, to transfer heat to the interior of the heater treater; and
wherein the heater treater includes a fire tube that was intended to burn a fuel in the fire tube, for engaging the access opening
wherein the fire tube includes open ends and wherein the assembly includes plates to fluidly seal to the fire tube so the second heat transfer medium may circulate through the fire tube so that the second heat transfer medium directly contacts the inner walls of the fire tube.
2. The device of claim 1 , wherein the assembly includes a turbulator.
3. The device of claim 1 , wherein the assembly further includes an electric heater located so as to provide heat to second heat transfer medium after leaving the buffer tank.
4. The device of claim 1 , further including a temperature control valve between the buffer tank and the plates to control the temperature of the second heat transfer medium.
5. The device of claim 1 , further including temperature sensors engaging the secondary circuit and the interior of the heater treater.
6. The device of claim 1 , further including an expansion tank engaging the fire tube.
