A heat-insulating container being used under an environment where exposure to water of liquid is possible, includes a container main body having a substance holding portion which holds a substance at a temperature which is lower than a normal temperature on the inside of the substance holding portion; and a heat-insulating structure body which is provided in the container main body and includes at least a vacuum heat-insulating material. In addition, the vacuum heat-insulating material (10) includes an outer cover material (11) and an inner member sealed in a tightly closed and decompressed state on an inside of the outer cover material (11). In addition, the inner member is configured of a material which does not generate hydrogen in a case of coming into contact with the moisture of the liquid.

Disclosed is a method for reducing the natural evaporation rate of an LNG storage tank. The method for reducing the natural evaporation rate of an LNG storage tank comprises the steps of: manufacturing an LNG storage tank including a primary insulation layer and a secondary insulation layer; connecting one end of a second vacuum hose to the secondary insulation layer; connecting the other end of the second vacuum hose to a vacuum pump; and actuating the vacuum pump so as to lower the internal pressure of the secondary insulation layer. The method enables the inside of the secondary insulation layer to be a vacuum, and thus lowers the moisture content of plywood included in the secondary insulation layer.

An apparatus includes a cryogenic tank disposed within an insulation tank such that an annulus is formed therebetween. The apparatus also includes a first heat transfer element configured to absorb heat from the cryogenic tank and a second heat transfer element configured to discharge heat into an ambient region proximate the insulation tank. The apparatus has legs between the first heat transfer element and the second heat transfer element, and an energy source configured to provide a heat flux through the legs.

A structure of a horizontal type cylindrical double-shell tank (8) mounted on a ship includes: an inner shell (2) storing a liquefied gas; and an outer shell (3) forming a vacuum space between the inner shell (2) and the outer shell (3). A pair of support units (4A, 4B) supporting the inner shell (2) is disposed between the inner shell (2) and the outer shell (3). Each support unit includes: a plurality of cylindrical elements arranged in a circumferential direction of the tank (8) such that an axial direction of each of the cylindrical elements coincides with a radial direction of the tank (8); a plurality of inner members each holding an end portion of a corresponding one of the cylindrical elements at the inner shell (2) side; and a plurality of outer members each holding an end portion of a corresponding one of the cylindrical elements at the outer shell (3) side. Each of the cylindrical elements is made of glass fiber reinforced plastic.

The invention relates to a method for generating and/or amplifying and/or boosting a desired vacuum in a vacuum insulation layer of a vacuum insulated storage container installed in a vehicle, for liquid or cryogenic gases. The vehicle is taken, for example by the vehicle user to a evacuation station, where a corresponding maintenance of the vacuum insulation, that is, an amplification of the vacuum in the vacuum insulation layer, is carried out by connecting said insulation to an evacuation system. The storage container can be filled with liquefied or cryogenic or compressed gas at the evacuation station for carrying out said method. Said type of evacuation station can have an evacuation system to which a plurality of storage containers can be connected in parallel and substances suctioned from the vacuum insulation layer of a storage container can be liquefied by means of the cold of the cryogenically stored gases at the station.

A suspension system (3) for an inner container (2, 2') mounted for thermal insulation in an outer container (1, 1') has a single fixed bearing (30, 31, 32, 33, 34, 35, 36, 37, 38, 39) comprising fixed bearing securing elements (5, 5', 5", 5"') which engage the outer container with one end and the inner container with the other end and which can be stressed in tension and in compression, the fixed bearing securing elements (5, 5', 5", 5"') being distributed around an annular space (7) between the inner container (2, 2') and the outer container (1, 1'), and the fixed bearing securing elements (5, 5', 5", 5"') being distributed around the annular space (7) and engaging the outer container (1, 1'). A floating bearing (41, 42, 43, 44, 45) in the form of a floating bearing ring (10, 10') can also be provided in the outer container (1, 1') to support the inner container (2, 2'), with annularly distributed floating bearing securing elements (11, 11') which engage the floating bearing ring (10, 10') with one end and the inner container or outer container with the other end and which can be stressed in tension and in compression. The floating bearing ring (10, 10') can be spring-biased by means of tension springs (12) or compression springs (13).

摘要:
A cryogenic fluid cylinder includes an inner vessel for holding cryogenic fluid, a cylindrically shaped outer vessel having a vertical longitudinal axis surrounds the inner vessel and forms an insulating space there between, and operating controls located on a top of the outer vessel. Customer or end user operating controls include a liquid-use valve for selectively dispensing liquid cryogen, a pressure-building valve for selectively controlling a pressure building circuit, and a gas-use valve for selectively dispensing cryogen gas. Supplier or maintenance personnel operating controls include an economizer regulator for selectively setting at least one desired pressure of the inner vessel, a vent valve for selectively venting cryogen fluid, and a vacuum pressure port for indicating vacuum pressure between the vessels. The end user controls are located on a front side of the outer vessel while the supplier controls are located on a rear side of the outer vessel.
