  • Patent number: 8640907
    Abstract: Floating roof tanks typically have a leg-actuated pressure-vacuum vent to provide relief upon emptying or filling the space below the roof. This vent leg must hit prior to other legs requiring additional working capital inventory (heel). This retrofit non-leg actuated pressure vacuum (P-V) vent reduces inventory. This P-V vent retrofit provides necessary pressure or vacuum management and at less required tank bottom inventory. The retrofit vent also eliminates the leg-actuated P-V vent.
