Abstract
Example flare gas capture apparatus, control, and associated methods are disclosed herein. An example apparatus includes a fluid evacuation system operatively coupled to a gas flare line to evacuate gas from the gas flare line, and a valve operatively coupled to the gas flare line downstream of the fluid evacuation system and upstream of a vent of the gas flare line, the valve movable between a first position and a second position based on a pressure of the gas, the valve to restrict flow of the gas to the vent in the first position, the valve to enable the flow of the gas to the vent in the second position.
Claims20
An apparatus comprising:
- a fluid evacuation system operatively coupled to a gas flare line to evacuate gas from the gas flare line;
- and
- a valve operatively coupled to the gas flare line downstream of the fluid evacuation system and upstream of a vent of the gas flare line, the valve movable between a first position and a second position based on a pressure of the gas, the valve to restrict flow of the gas to the vent in the first position, the valve to enable the flow of the gas to the vent in the second position.
A method comprising:
- activating a fluid evacuation system operatively coupled to a gas flare line to evacuate gas from the gas flare line;
- when a pressure of the gas in the gas flare line satisfies a threshold pressure, opening a valve operatively coupled to the gas flare line downstream of the fluid evacuation system and upstream of a vent of the gas flare line, the valve to enable flow of gas to the vent in an open position;
- and
- closing the valve when the pressure of the gas in the gas flare line does not satisfy the threshold pressure, the valve in a closed position to restrict the flow of the gas to the vent.
A system comprising:
- evacuation control circuitry operatively coupled to a fluid evacuation system, the fluid evacuation system operatively coupled to a gas flare line, the evacuation control circuitry to activate the fluid evacuation system to evacuate gas from the gas flare line;
- pressure monitoring circuitry to determine a pressure of the gas in the gas flare line based on data from a sensor operatively coupled to the gas flare line;
- and
- valve control circuitry operatively coupled to a valve, the valve operatively coupled to the gas flare line downstream of the fluid evacuation system and upstream of a vent of the gas flare line, the valve control circuitry to:
- move the valve to a first position when the pressure of the gas satisfies a threshold pressure, the valve to enable flow of the gas to the vent in the first position;
- and
- move the valve to a second position when the pressure of the gas does not satisfy the threshold pressure, the valve to restrict the flow of the gas to the vent in the second position.
