WebWhen an emergency vent opening must be extended to the building exterior, the additional length through which vapor must flow to escape the tank will lead to excessive back-pressure on the tank if the vent pipe diameter is inadequate. In a worst-case scenario of a fire engulfing a tank with a large surface area, vent flows would be enormous and WebSep 1, 2003 · Conservation vents are the typical devices one uses to control emissions from storage tanks. They are weighted and usually rated ounces/sq. in. because most atmospheric storage tanks cannot handle much pressure. The weights minimize the "breathing" loss that occurs when the tank temperature changes.
