  • Patent number: 6339996
    Abstract: A compressed natural gas (CNG) transportation system designed to operate at or just below ambient temperatures, that is either ship-based, truck-mounted, or modular for container transportation. The system is an alternative to LNG, pipeline, or conventional CNG transportation systems, where the foregoing modes of transportation are not practical or feasible. The use of composite pressure vessels provides a critical advantage over conventional CNG concepts that use steel or steel lined pressure vessels. The rupture characteristics of composite pressure vessels exceed those of conventional steel or steel lined pressure vessels. The substantial weight reduction of pressure-equivalent composite pressure vessels overcomes the weight-related problems associated with steel or steel lined pressure vessel concepts. The corrosion resistance of composite pressure vessels allows for the transportation of raw CNG and or compressed natural gas liquids (CNGL) which are most often corrosive.

    Abstract: A marine gas storage and transport system formed of small diameter steel pipe, which is coiled and stacked in a specific manner. The system is suitable for use on top of a barge or inside the holds of a ship, when contained within a secondary containment system. The specific manner in which the pipe is coiled is such that about 97% of the total length of pipe coiled may be described by constant curvature or pure circles. Additionally these circles lie directly on top of one another about 94% of the time and vertical stacking stresses are minimized. Only about 6% of the pipe is involved in crossover geometry. This method, of about 97% circular coiling, combined with about 3% transitional coiling results in a continuous length of pipe that nests easily, provides greatly reduced contact stresses and is very economic to construct due to its ease of nesting and it's long lengths of constant curvature.

    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: 5868271
    Abstract: A light gas tank with a safe inlet device includes a ring fixed on an upper surface of a light gas tank. The ring has a center fuel inlet hole, and an inverted L-shaped gas inlet on one side of the wall and an inverted L-shaped passageway on the other side of the wall. An L-shaped air tube is located in a hollow interior of the tank, having its upper end welded with a vertical portion of the gas inlet and air holes in a lower portion. An air pumping device can pump air into an inlet nozzle, the gas inlet of the ring and the L-shaped air tube, and then out of the air holes into the fuel stored in the tank to fuse with the fuel to become fuel gas for use through a control valve fixed on the tank. The pumping device is operated only when fuel gas is to be used, so no large gas pressure is produced in the tank, diminishing potent danger of explosion.

  • Patent number: 5797513
    Abstract: An insulated vessel (10, 100, 130) is provided which is adapted to receive a low or high temperature material to be insulated from the environment. The vessel comprises inner and outer membranes (20, 110, 140) and (30, 120, 150) and an outer casing (40, 170). The inner membrane defines an inner cavity for receiving the low or high temperature material and has a first portion which defines an entrance into the inner membrane. The outer membrane encases the inner membrane such that a space is defined between the inner and outer membranes. The outer membrane includes a second portion which is positioned adjacent to the first portion. An insulating material (60, 160) is located in the space between the inner and outer membranes. The inner and outer membranes are joined together so as to seal off the space from the environment. The space is evacuated to less than atmospheric pressure. The outer casing surrounds the outer membrane and has sufficient strength to provide structural and abuse integrity to the vessel.

  • Patent number: 5651473
    Abstract: The invention consists of an outer jacket surrounding and spaced from an inner tank to create an insulated space therebetween. The inner tank closely conforms to the outer jacket such that the insulation chamber is substantially uniform and the capacity of the inner tank is increased. An insulated support assembly that extends into the inner tank allows communication between the exterior of the vessel and the inner tank for pipes, pressure gauges and the like. The support assembly allows for a long insulated path without reducing the capacity of the tank to the same extent as the prior art devices.

  • Patent number: 5533340
    Abstract: A double-walled container for transporting and storing a liquified gas or cryogenic liquid at low temperature. The container has an inner liquified gas holding vessel and an outer shell enclosing the inner vessel. The outer shell is coaxial with the vessel and of such a size as to provide a closed insulated space all around it. The inner vessel is suspended by its ends within the outer shell, with one end of the vessel being rigidly connected to the adjacent end of the shell while the other opposite end of the vessel is slidably connected to the other adjacent end of the shell so as to allow thermal expansion of the inner vessel and outer shell with respect to each other. Closable feeding and exit pipes pass through the outer shell and the inner vessel for introducing and draining the liquified gas into and off from the inner vessel. This container is light weight and can be of very great size; it can be used for the international transportation of liquid hydrogen by air, sea, rail or road.
