Abstract
A storage system for a petroleum product and related methods includes a vapor barrier including at least one layer having an ultra high molecular weight polyethylene material configured to inhibit absorption of a petroleum product therethrough. Such vapor barrier may be a coated fabric with the ultra high molecular weight polyethylene material and be configured to fluidly seal against a surface. The vapor barrier is further configured to be incorporated into any such storage system, which further includes a floating roof seal, a tank liner seal, and/or a leg boot seal.
Claims20
A storage system for a petroleum product, comprising:
- (a) a vapor barrier including at least one layer having a first ultra high molecular weight polyethylene material configured to inhibit absorption of a petroleum product therethrough and be received against a surface for fluidly sealing thereagainst.
A storage system for a petroleum product, comprising:
- (a) an annular vapor barrier including at least one layer having an ultra high molecular weight polyethylene film layer and defining an annular hollow, wherein the annular vapor barrier is configured to inhibit absorption of a petroleum product therethrough;
- (b) a mounting plate;
- and
- (c) an annular foam member received within the annular vapor barrier and attached to the mounting plate, wherein the annular vapor barrier is configured to surround the annular foam member and fluidly seal the annular foam member from the petroleum product,
- wherein the annular vapor barrier covers the annular foam member such that the annular vapor barrier is configured to fluidly seal against a tank wall while being further configured to move along the tank wall.
A method of fluidly sealing a petroleum product from an environment with a storage system, the storage system including a vapor barrier with at least one layer having a first ultra high molecular weight polyethylene material, the method comprising:
- (a) inhibiting absorption of the petroleum product through the vapor barrier thereby fluidly sealing the petroleum product in the storage system.
