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 is directed to a method of decreasing the rate of escape a gas from a breached containment system by introducing into the containment system a plurality of objects that create a tortuous path for the gas to get to the point of breach thereby substantially reducing the degree of damage done by the breach.
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:
The present invention relates to pressure vessels comprising a composite dome and metal cylindrical center section where both the dome and the center section are of such a thickness as to be capable of withstanding the pressure exerted by a fluid contained in the vessel. 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:
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
