Abstract
A storage tank having an inner vessel disposed within an outer vessel. A common-access tube or conduit is used to route the various fluid flow lines into the interior of the inner vessel. The common-access tube facilitates modular construction and assembly of the storage tank.
Claims12
A cryogenic storage tank comprising:
- a fluid-tight outer vessel;
- a fluid-tight inner vessel disposed within the outer vessel;
- a vacuum between the inner and outer vessels;
- a tube communicating with the vacuum and extending into an interior of the inner vessel, a first portion of the tube within the interior of the inner vessel having a first radial cross-sectional area of a first value, a second portion of the tube within the interior of the inner vessel having a second radial cross-sectional area of a second value, the second value being greater than the first value, the second portion being an end portion, and the first and second portions being axially aligned;
- a plate attached to the tube;
- and
- a plurality of fluid lines extending from an exterior of the inner vessel to an interior of the inner vessel through the tube and the plate.
