Abstract
A cryogenic storage system basically includes a first cryogenic storage tank, a second cryogenic storage tank, a fluid transfer line and a cryogenic containment structure. The first cryogenic storage tank has a first predetermined capacity of liquefied gas. The second cryogenic storage tank has a penetration free bottom and a second predetermined capacity of the liquefied gas that is larger than the first predetermined capacity of the first cryogenic storage tank. The fluid transfer line is fluidly connected between the first cryogenic storage tank and the second cryogenic storage tank. The heat exchanger converts liquid exiting the first cryogenic storage tank to a higher pressure gas that is used as a motive force to move liquidized gas out of the second cryogenic storage.
Claims19
A cryogenic storage system comprising:
- a first cryogenic storage tank having a first predetermined capacity of liquefied gas;
- a second cryogenic storage tank having a penetration free bottom and a second predetermined capacity of the liquefied gas that is larger than the first predetermined capacity of the first cryogenic storage tank;
- a first outlet line fluidly connected to a bottom of the first cryogenic storage tank and fluidly connected to an upper portion of the second cryogenic storage tank at a point of the upper portion that is above a level of the liquefied gas within the second cryogenic storage tank for removing the liquefied gas from the first cryogenic storage tank, the first outlet line including at least one control valve to regulate the flow of the liquefied gas from the first cryogenic storage tank to the second cryogenic storage tank;
- a second outlet line connected to the upper portion of the second cryogenic storage tank at a point above the level of the liquefied gas within the second cryogenic storage tank and extending into the second cryogenic storage tank through the upper portion to a point below the level of the liquefied gas within the second cryogenic storage tank for dispensing the liquefied gas from the second cryogenic storage tank through the upper portion of the second cryogenic storage tank;
- and
- a cryogenic containment structure positioned to contain spillage of liquefied gas from the first cryogenic storage tank;
- the second cryogenic storage tank including an inner container having a penetration free bottom and an outer container having a penetration free bottom;
- the first cryogenic storage tank containing the liquefied gas at a higher pressure than a pressure of the liquefied gas contained in the second cryogenic storage tank such that the liquefied gas exiting the first cryogenic storage tank is used as a motive force to move the liquefied gas out of the second cryogenic storage tank through the upper portion of the second cryogenic storage tank via the second outlet line without using an internal pump.
