Processes and apparatus for the prevention, detection and/or repair of leaks or avenues for leaks from above-ground storage tanks

摘要

A storage tank apparatus is described which comprises an above- ground storage tank having a first, lowermost bottom, a second bottom joined to the walls of the storage tank above the first, lowermost bottom and defining a space between the first and second bottoms, structural support means placed in the space between the first and second bottoms for supporting the second bottom above the first bottom, and a plurality of sampling ports spaced about the perimeter of the storage tank and permitting access to the space between the first and second bottoms and to the avenues for fluid communication provided therethrough by the structural support means. Processes for detecting leaks and avenues for leaks of materials placed in the storage tanks of such apparatus are also described.
