Green Products for Storage Tanks
Aboveground Storage Tank (AST) owners and managers can help reduce environmental contamination by using Mesa's line of emission control products. These "green" products for ASTs include MesaThane floating roof seal materials, Roof Leg Socks and Vapor Guard® Gauge Pole Covers. MesaThane seal materials have been in use by customers since Mesa's formation in 1967--over 40 years of tried-and-true experience in all ranges of storage products and applications. Mesa has manufactured Roof Leg socks since 1989 and they are in service with a vast array of products. Mesa introduced Vapor Guard Gauge Pole Covers in 2001 with wide acceptance throughout the industry. To maintain a long product service life, Mesa's engineers analyze each application for seal materials, Leg Socks and Gauge Pole Covers to determine the material and configuration that best suits each application. MesaThane floating roof seal materials are suitable for several "green" applications including floating roof perimeter seal materials, i.e. primary and secondary curtain seals, foam log/envelope seals, vapor bladders, pontoon liners, repair bladders and other custom applications. Leg Socks are designed to reduce emissions caused by vapors escaping from floating roof support legs.Roof Leg Socks (also referred to as deck leg covers in the storage tank industry) form a covering for the support legs to seal in hydrocarbon vapors.
Vapor Guard® Gauge Pole Covers reduce hydrocarbon vapors from escaping through slots in AST slotted gauge poles. Gauge Pole Covers form a casing around the exterior of the slotted gauge pole. When covering an uncontrolled gauge pole in a petroleum storage tank with Mesa's Vapor Guard, tank owners can reduce emissions by as much as tens of thousands of pounds per year. In addition to reducing environmental contamination, tank owners benefit from Mesa's green products by reducing product loss from their tanks. Product loss is reduced by sealing in hydrocarbon vapors at specific areas on the floating roof, namely the rim space, gauge pole and support legs. By meeting environmental regulations with the use of Mesa's green products, tank owners realize additional benefits of compliance and operational efficiency.
