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 is directed to a polymeric pressure vessel comprising a wall prepared by living polymerization such that the wall comprises a single layer of polymer having two sub-layers, an inner sub-layer that is not a composite and an outer layer that is.
Abstract:
A storage system for compressed natural gas which includes at least one storage vessel for storing CNG and a cooling station wherein the storage vessel is connected to the cooling station so that CNG may be stored in the storage vessel after had been passing through the cooling station and once the stored gas conditions fall out a set range, it is cooled in the cooling station, and returned to the storage vessel, wherein the storage vessel is thermally insulated from the exterior thereof thanks to the composite materials and especially glass-reinforced polymers whose pressure vessels are made.
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:
An internally coated pipe (10) for CNG distribution or delivery is disclosed, wherein the pipe is made of a thermosetting plastic material (3), and the internal coating is made of a metallic material (5). The thermosetting material (3) provides the required strength for the pipe (10), for handling the pressures to which the pipe will be exposed, e.g. up to 100 bar, whereas the metallic layer (5) provides the required impermeability to the component parts of the CNG.
Abstract:
The present invention relates to a high pressure vessel for containing or transporting gas at ultra-high pressures. More particularly it relates to such vessels for containing or transporting compressed natural gas at these pressures and methods of manufacturing them. The present invention also relates to a method of storing or transporting gas onshore or offshore.
Abstract:
A watercraft comprising a diesel fuel tank for fuelling general shipping requirements of the watercraft such as motoring from one location to another, wherein the watercraft additionally has a CNG pressure vessel thereon for storing CNG therein, said CNG being useable by the watercraft, from the pressure vessel, for powering an engine for coastal manoeuvering of the watercraft.
Abstract:
An ISO modal container for storage and transportation of a CNG pressure vessel comprises a main longitudinal portion and two end caps, one at each end of the main longitudinal portion. The container comprises a frame body for housing a single pressure vessel inside said frame body. The frame body comprises two sides connected by longitudinally extending beams. A pair of attachments, one at each end of the pressure vessel, holds the pressure vessel suspended in place inside the frame body, with the longitudinal portion of the pressure vessel substantially parallel to the longitudinally extending beams of the frame body of the container. The pressure vessel is typically of the type 3 or type 4 class.
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 filament-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.
