SYSTEMS AND METHODS TO PREVENT EXPLOSIONS IN A TANK USING AUTOMATED GAS HARVESTING AND PURGE SAFETY DEVICES

Provided is a flowback system and method. The flowback system, in one aspect, include a tank, a transfer pump, a low-pressure vent line coupled between a vent of the tank and a first flare tip, and a high-pressure gaseous hydrocarbon line coupled to a second flare tip. In accordance with yet one other aspect, the flowback system includes a control system including a sensor, a valve and a valve controller coupled to the valve, the valve of the control system coupled between the low-pressure vent line and the high-pressure gaseous hydrocarbon line, the control system configured to sense an unsafe system event and actuate the valve to supply high-pressure gaseous hydrocarbons from the high-pressure gaseous hydrocarbon line to the low-pressure vent line.
