Abstract: An improved cryogenic liquid storage tank features a main tank containing a ullage tank. The top portion of the main tank communicates with the bottom portion of the ullage tank through a pipe segment and an opening in the ullage tank. The pipe segment is dimensioned and positioned so that the main tank fills with incoming cryogenic liquid while the ullage tank remains primarily empty. The restricted flow into the ullage tank causes the flow of cryogen into the main tank to decrease when the main tank is nearly full. This decrease in flow is utilized to terminate the filling of the tank. Removal of product from the main tank decreases the pressure and the liquid level therein so that liquid flows out of the ullage tank and is unable to return.

Abstract: A convoluted or multiple-pass neck tube joins inner and outer elements of a vacuum-jacketed vessel. The additional length of the convoluted neck tube creates an increased distance for heat to conduct from the outer to the inner vessel. As such, a convoluted neck tube can be substitute in place of a straight neck tube or a bellows neck tube to reduce heat gain into the inner vessel. An additional benefit achieved by the convoluted neck tube is greater flexibility of the neck tube, thus yielding more stress resistance.

Abstract: A method and apparatus for safely, conveniently, and inexpensively liberating gas from gas hydrates includes the use of a device, provided adjacent to or in the bulk gas hydrates, for exposing the gas hydrates to heat from a gas or liquid (preferably steam). The gas hydrates can be directly exposed to the gas or liquid or indirectly exposed through a thermally conductive coil or channel. The heat from the gas or liquid dissociates the gas hydrates into the corresponding gas component and water component. After liberation, the gas component can be collected for further storage, transport, or use. The apparatus further includes a mechanism for moving at least a portion of the gas or liquid through the device for exposing the gas hydrates to heat. The device for exposing the gas hydrates to heat also can be movable, so it can be maintained in close proximity to or in contact with the gas hydrates for continued efficient gasification of the hydrates.

Abstract: An insulated structure is formed by injection of a foamed thermal-insulating material created by foaming into a space between a plastic board and metal plate with a disposition of copper pipes.

Abstract: A gas hydrate storage reservoir includes at least one insulated wall defining an opening and a sunlight permeable top covering the opening. A gas-tight, gas hydrate storage cavity is defined within the top and the wall(s). A cover element is provided to cover at least a portion of the top to prevent sunlight from passing through that portion of the top. The gas storage reservoir also includes devices for removing gas and water from the storage cavity. In use, when gas is desired by the user, the cover element is removed from at least a portion of the sunlight permeable top so that sunlight will pass through the top and into the storage reservoir. Heat energy from the sun warms the exposed gas hydrates, thereby forcing the hydrates to dissociate into gas and water. The gas is removed from the tank and transported to an appropriate location for use. When sunlight is unavailable or when additional gas is needed than that produced by dissociation via the sun, an external, auxiliary heater (e.g.
