Abstract
An improvement is disclosed for a flare seal system of the type which includes a flare seal drum containing a body of liquid at a predetermined level and a waste gas inlet conduit extending vertically into the liquid body and having an opening beneath the liquid level, whereby gases discharging from the inlet conduit pass through the liquid body before discharging from the drum to a flare stack. The improvement enables the reduction of gas pulsing from the seal drum, and includes flap valve means pivotally mounted at the wall of the inlet conduit. The flap valve is openable at a point beneath the liquid level, and includes means to bias the valve to a closed position. The inlet gas flow pressure acts against the bias to open the valve, to enable gas flow into the liquid and thence to the flare stack.
