Title:
MULTIPLE SHELL TANK, SHIP, AND GAS PRESSURE ADJUSTMENT METHOD
Document Type and Number:
Japanese Patent JP2022157756
Kind Code:
A
Abstract:
To keep a pressure of a gas layer in an inner tank low, while suppressing condensation of a gas in a space between the inner tank and an outer tank.SOLUTION: A multiple shell tank includes: an inner tank for storing a low temperature liquid inside; an outer tank housing the inner tank; and a housing structure housing the outer tank. A heat insulation space between the inner tank and the outer tank is filled with a gas of the kind same as a gas obtained by vaporization of the low temperature liquid, a pressure of a gas layer inside of the inner tank is higher than a pressure of the heat insulation space, and a pressure of the heat insulation space is lower than a pressure of a holding space between the outer tank and the housing structure.SELECTED DRAWING: Figure 2
