Cryogenic storage tank

摘要

An apparatus and method for constructing a cryogenic storage tank (700) having a welded inner tank (702), an outer shell (704) surrounding the welded inner tank (702), a concrete foundation (728) comprising a raised portion (752), a plurality of cellular glass blocks (734) positioned directly on top of the raised portion (752) of the concrete foundation (728), a leveling course of concrete (736) poured on top of the uppermost layer of the plurality of cellular glass blocks (734), and a mounting apparatus (718) affixed to the concrete foundation (728), where the welded inner tank (702) is positioned on top of the leveling course of concrete (736) and the outer shell (704) is affixed to the mounting apparatus (718) at locations around the periphery of the outer shell (704).

主权项

1. A cryogenic storage tank, comprising:
a concrete foundation comprising a lower portion forming a first upper surface and a raised portion forming a second upper surface, wherein the second upper surface is located above the first upper surface; a plurality of cellular glass blocks positioned directly on top of the second upper surface of the concrete foundation; a leveling course of concrete poured on top of the uppermost layer of the plurality of cellular glass blocks; a mounting apparatus affixed to the concrete foundation, wherein the mounting apparatus comprises a compression ring, and the second upper surface of the concrete foundation is located above the compression ring; a welded inner tank comprising an inner tank floor plate, a plurality of inner tank wall staves, and an inner tank roof dome, wherein the welded inner tank is positioned on top of the leveling course of concrete; and a bolted outer shell comprising a plurality of bolted outer shell wall staves and an outer shell roof dome, wherein the bolted outer shell is positioned on top of the mounting apparatus, surrounding the welded inner tank, and spaced apart from the welded inner tank such that the plurality of inner tank wall staves are positioned adjacent to the plurality of bolted outer shell wall staves and the inner tank roof dome is positioned adjacent to the outer shell roof dome; wherein the bolted outer shell is affixed to the mounting apparatus at locations around the periphery of the bolted outer shell; wherein the compression ring has a plurality of anchor bolt holes to serve as a template for affixing the bolted outer shell to the mounting apparatus and concrete foundation.
