The vapor barrier for flammable liquid storage tanks provides a gas impermeable layer for covering the surface of a flammable liquid stored within a conventional flammable liquid storage tank, a tanker, a vessel or the like. The vapor barrier is formed from a plurality of spherical buoyant members.
The vapor barrier for flammable liquid storage tanks provides a gas impermeable layer for covering the surface of a flammable liquid stored within a conventional flammable liquid storage tank, a tanker, a vessel or the like. The vapor barrier is formed from a plurality of spherical buoyant members. Each spherical buoyant member has a heat-resistant core or shell, a heat-reactive intumescent or flame retardant layer formed on an outer surface of the heat-resistant core, and an antistatic and oil-phobic layer formed on an outer surface of the heat-reactive intumescent layer. The vapor barrier may further be used with liquid storage tanks in which separation between the liquid and vapor phases is beneficial to prevent oxidation or other undesirable reactions.
