Flare Knock Out Drums (FKOD’s) are designed to be as compact as possible, usually with a small building for the controls. We can customize the size, pressure and any other requirements you require.
All flare, vent, and relief systems must include a liquid knockout drum. The knockout drum removes any liquid droplets that carry over with the gas relief sent to the flare. Most knockout drums are horizontal. A horizontal knockout drum must have a diameter large enough to keep the vapor velocity low enough to allow entrained liquids to settle or drop out.
Knockout drums operated at atmospheric pressure should be sized to handle the greatest liquid volume expected at the maximum rates of liquid buildup and pump out.
Knockout drums normally are operated at atmospheric pressure. Some applications require 50psi MAWP in order to contain a possible explosion. Stoichiometric hydrocarbon/air explosions produce peak pressures seven to eight times the normal pressure.
