Abstract:
The present invention relates to pressure vessels comprising a composite dome and metal cylindrical center section where the dome is of such a thickness as to be capable of withstanding the pressure exerted by a fluid contained in the vessel but the cylindrical center section is not. To overcome this shortcoming the cylindrical center section is hoop-wrapped with a filamentous composite. Methods of coupling the dome to the center section are also set forth.
Abstract:
This invention relates to methods of fabricating components of a pressure vessel using a dicyclopentadiene prepolymer formulation in which the purity of the dicyclopentadiene is at least 92% wherein the formulation further comprises a reactive ethylene monomer that renders the prepolymer formulation flowable at ambient temperatures and to pressure vessels that are fabricated by said methods.
Abstract:
This invention relates to a metal pressure vessel with a cylindrical center section greater than about 3 meters in diameter and one or two frustum end sections having a diameter at the truncated apex of the frustum of about two meters or less.
Abstract:
This invention is directed to a pressure vessel comprising a determinate-dimensioned liner that can be expanded to permit on-loading and collapsed to assist off-loading of a compressed fluid.
Abstract:
A vessel emptying system for emptying CNGs from a vessel used to transport CNG, the vessel being one of a plurality of cylindrical containers that are arranged vertically, with substantially parallel axes, wherein said system is arranged to expand the CNG through a turboexpander-compressor device (40, 50), the turboexpander-compressor device (40, 50) being adapted to use kinetic energy from the resulting rotation or movement of that turboexpander-compressor device (40, 50) in a secondary gas processing step of the system. publication
Abstract:
A pressure vessel for storage and transportation of CNG comprises a body, which defines an internal volume in which the CNG is stored and transported. An inlet is provided through which the CNG can be loaded into the internal volume of the vessel. At the end of said inlet there is a CNG expansion section through which the CNG expands into the vessel when loaded. The pressure vessel further comprises a CNG loading appendage for injecting the CNG at a point inside the internal volume of the vessel, thereby increasing the space between the expansion point of the CNG and the walls of the vessel.
Abstract:
A pressure vessel is produced for storing and transporting CNG. The vessel comprises a body defining an internal volume in which the CNG can be stored, and an inlet for loading the CNG into the vessel. The body of the vessel comprises a structural shell made entirely of a fibre-reinforced fibre-wound composite material, which is provided with fibres to carry mechanical loads and a matrix to keep the fibres together and to make the composite impermeable to the CNG. Because the vessel is not provided with any liner, the CNG is in direct contact with an inner side of the structural shell.
Abstract:
A pressure vessel for containment of CNG comprises a cylindrical body enclosed between two end domes. The cylindrical body and the domes define a convex volume and surface for accommodating the CNG. The cylindrical body has a diameter, and a length. Each of the domes has a base diameter matching the diameter of the cylinder, and an axial height. The overall length of the pressure vessel is defined by the axial length of the cylindrical body and the axial heights of the domes. The ratio between the length of the pressure vessel and the diameter of the cylindrical body is comprised in the range between one and two, or equal to one or two, so that the resulting pressure vessel looks compact, and has a good proportion of internal volume per unit surface.
Abstract:
A reversible fastening device (50) for reversibly fastening connecting means (51) connecting a first (52) and a second member (53); the connecting means (51) being housed entirely inside the first member (52); and the device (50) being characterized in that, at a first reversible stage, the connecting means (51) are moved from a withdrawn position to an extracted position projecting with respect to the first member (52); and in that the desired reversible fastening of the connecting means (51) connecting the first (52) and the second (53) member is achieved in the extracted position.
