International Classification:

B01D 3/00

Abstract:

A structure for extreme thermal cycling has a support element that supports a vessel primarily by bearing and frictional forces rather than by welds. The support element has a bearing portion that tapers inwardly beneath a knuckle that separates a cylindrical section of the vessel from a sloped lower section. The bearing portion of the support element follows that slope, providing an extended area of contact between the support element and the vessel. An annular section of the support element can be heated and expanded before placing it around the cylindrical section of the vessel to provide pre-stressing. If required, a strap may extend downwardly from the vessel over an upper edge of the support element.

Abstract:

A low-temperature/cryogenic liquid-storage structure has an inner tank liner made of conventional low-temperature/cryogenic tank-quality plates with structural members that provide flexibility. The plates are mounted on connectors that accommodate movement of the liner with respect to the bearing wall. The plates have a thickness of between 1/16″ and ″ and a surface area of at least 100 square feet. The structural members are conventional construction materials that have a wall thickness of more than 1/16″. Load-bearing insulation extends between the outer surface of the inner tank liner and the inner surface of an outer bearing wall that is impervious to vapor.
