  • Patent number: 6128908
    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.

  • Patent number: 6028235
    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.

  • Patent number: 5983647
    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. A non-halogenated organophosphorus compound having a molecular weight over 150 as an additive with an OH group as a functional group is mixed with the raw materials of the foamed thermal-insulating material including polyol, a foam stabilizer, a catalyst, a foaming agent having at least one component of hydrocarbon, and an organic polyisocyanates. By adding a non-halogenated organophosphorus compound, which has a molecular weight over 150 as an additive with an OH group as a functional group, the burning rate of the foamed thermal-insulating material becomes the same as that of the foamed thermal-insulating material which uses CFC11 as a foaming agent.

  • Patent number: 5964093
    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.

  • Patent number: 5901557
    Abstract: There is provided a vessel storing cryogenic fluid having a passive thermodynamic venting system for effectively and reliably transferring heat in a reduced-gravity environment. The storage vessel has a storage tank for holding the cryogenic fluid under pressure. The storage vessel is compartmentalized using a screen trap so that the heat exchanger of the venting system extends through a compartment which includes only the liquid phase of the cryogenic fluid. A screen gallery, screen trap and vane assembly cooperate to separate the gas and the liquid phases of the cryogenic fluid. The thermodynamic venting system includes a throttle device for reducing the temperature of cryogenic fluid. A conduit in contact with heat exchange elements transfers heat from the liquid phase of the cryogenic fluid to a relief valve for venting the heat external of the storage tank.

  • Patent number: 5765379
    Abstract: It is already known that heat insulating elements, e.g. in refrigerators, may be more efficient if they are sealingly encapsulated and subjected to a high vacuum. Based on theoretical considerations in connection with foam having small cells it has been relevant to use a vacuum of the magnitude of 0.001 mbar and hermetical sealing of the elements. According to the invention it has been found that practically well usable results are achievable at much higher pressures, viz. in a range about 1 mbar, which is much easier to produce. Consequently, a further simplification can be obtained by renouncing the hermetical sealing and relying on an only "almost tight" sealing, combined with the use of an operationally active vacuum pump provided in each apparatus unit.

  • Patent number: 5752386
    Abstract: A method of draining a tank that has been containing liquid gas, and a plant for use in such draining. After draining of the major part of the tank contents, but while residual contents of gas are present in vapourized state in the tank, the residual contents are conveyed for exchanging heat directly or indirectly with cold nitrogen. Nitrogen is vapourized and heated and conveyed to the tank, while the residual gas is cooled and condensed and conveyed to a collector tank. The plant comprises a heat exchange system connected to the supply of nitrogen, and residual gas is forced from the tank to be drained and through the heat exchange system in order to cause vapourization and heating of nitrogen to be conveyed to the tank, in such a manner that the residual gas from the tank condenses, whereby a collector container is connected for receiving condensed residual gas.
