ABSTRACT:
A vaporless liquid containment system for storing volatile and other liquids while preventing the formation and escape of vapors. The vessel includes a base and a first membrane, the first membrane defines a fluid containment space for containing stored liquid. A fluid-tight gas containment space is located above the first membrane. The gas containment space is adapted to house a gas under pressure. As liquid to be stored is supplied to and withdrawn from the fluid containment space, the gas housed in the gas containment space supplies fluid pressure to the first membrane so that the pressure on the first membrane is maintained above the vapor pressure of the stored liquid. This prevents the formation of vapor caused by the evaporation of the stored liquid.
