Abstract
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).
Claims20
A cryogenic storage tank, comprising:
- a concrete foundation comprising a raised portion;
- a plurality of cellular glass blocks positioned directly on top of the raised portion of the concrete foundation;
- a leveling course of concrete poured on top of an uppermost layer of the plurality of cellular glass blocks;
- a mounting apparatus affixed to the concrete foundation;
- 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.
A method for construction of a cryogenic storage tank, comprising the steps of:
- pouring and curing a concrete foundation including a raised portion by using a mounting apparatus embedded in the concrete foundation as a form for the raised portion;
- installing a plurality of cellular glass blocks on the raised portion of the poured and cured concrete foundation;
- pouring and curing a leveling course of concrete on top of the installed plurality of cellular glass blocks;
- installing a floor plate on top of the leveling course of concrete;
- installing a plurality of bolted wall staves, arranged in a plurality of courses including a bottom course and a top course, to the concrete foundation by securing the bottom course of bolted wall staves to the embedded mounting apparatus;
- welding a plurality of wall staves to the floor plate, the plurality of welded wall staves arranged in a plurality of courses, including a top course;
- welding a first roof dome to the top course of the plurality of welded wall staves to form a welded inner tank;
- and
- installing a second roof dome to the top course of the plurality of bolted wall staves to form a bolted outer shell.
A cryogenic storage tank, comprising:
- a welded inner tank;
- an outer shell surrounding the welded inner tank;
- a concrete foundation comprising a raised portion;
- a plurality of cellular glass blocks positioned directly on top of the raised portion of the concrete foundation;
- a leveling course of concrete poured on top of an uppermost layer of the plurality of cellular glass blocks;
- and
- a mounting apparatus affixed to the concrete foundation;
- wherein the welded inner tank is positioned on top of the leveling course of concrete and the outer shell is affixed to the mounting apparatus at locations around the periphery of the outer shell.
