Abstract:
Containers suitable for storing pressurized fluids at cryogenic temperatures of null62null C. (null80null F.) and colder are provided and comprise a self-supporting liner and load-bearing composite overwrap, whereby means are provided for substantially preventing failure of the container during temperature changes.
Abstract:
The invention relates to the partial or complete use of a pressurized gas cylinder known per se for compressed, liquefied or dissolved gases as a liner for a composite cylinder. This enables production costs of a composite cylinder to be reduced by null when compared to the costs arising from the production of a new composite cylinder using current manufacturing technologies.
Abstract:
Systems and methods for producing and storing pressurized liquefied natural gas (PLNG) are provided, wherein the systems and methods include (a) a natural gas processing plant suitable for producing PLNG; and (b) at least one container suitable for storing the PLNG, the at least one container comprising (i) a load-bearing vessel made from a composite material and (ii) a substantially non-load-bearing liner in contact with the vessel, said liner providing a substantially impermeable barrier to the PLNG. The systems and methods also preferably include (c) means for transporting the at least one container containing PLNG to an import terminal.
Abstract:
The invention relates to the partial or complete use of a pressurized gas cylinder known per se for compressed, liquefied or dissolved gases as a liner for a composite cylinder. This enables production costs of a composite cylinder to be reduced by ⅓ when compared to the costs arising from the production of a new composite cylinder using current manufacturing technologies.
Abstract:
A fill block is provided for a CNG fuel system for a transit bus or similar vehicle. The fill block includes a integral one piece body having first and second ends defining a length therebetween. The body has a main bore defined therein. A ball valve is received in the body and has a handle extending from the body. The ball valve is movable between open and closed positions, wherein the main bore is opened and closed, respectively. A fueling port is defined in the body and communicated with the main bore. A defueling port is defined in the body and communicated with the main bore. A fueling receptacle is connected to the fueling port. A defueling receptacle is connected to the defueling port. A defueling valve is provided for selectively communicating the defueling port with the main bore or isolating the defueling port from the main bore.
Abstract:
Glass-fibre reinforced plastic tank, for example for liquid petroleum gas under high pressure, compressed air for air brakes or for storage of acetylene. The tank is composed of two halves, the open ends of which are conically bevelled to form a male end and a female end, which are joined to each other by an adhesive. The reinforcement in the outer and inner layers of the halves contains essentially longitudinal glass-fibre strands and the intermediate layer contains essentially longitudinal glass-fibre strands and the intermediate layer contains essentially transverse glass-fibre strands. In the half with the male end, the longitudinal glass-fibre strands in the inner layer are densely located adjacent to each other, while the longitudinal glass-fibre strands in the outer layer lie in separate groups of densely arranged glass-fibre strands with the predetermined spacing between the groups of form channel-shaped spaces. In the half with the female end, the order is reverse. In order to store acetylene, a pre-fabricated absorbent body of porous material is enclosed in the tank when the tank halves are glued together.
Abstract:
Provided is an independent tank, and a manufacturing method therefor, for which local bending stress occurring on the vicinity of a boundary portion (welded portion) can be reduced without increasing plate thickness. An independent tank has at least one curvature change portion in which the curvature along the axial direction of plate members that form the tank changes along the axial direction. Both the inner peripheral surface and the outer peripheral surface of the plate member on the small curvature side are not flush with respect to the inner peripheral surface and the outer peripheral surface of the plate member on the large curvature side. The plate thickness center of the plate member on the small curvature side is offset toward the radial direction inner side or the radial direction outer side with respect to the plate thickness center of the plate on the large curvature side.
