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:
The present invention relates to a pressure vessel for containing or transporting pressurized gas. More particularly it relates to such vessels for containing or transporting compressed natural gas. The present invention also relates to a method of storing or transporting gas onshore or offshore. Moreover, the present invention relates to a vehicle for transporting gas, in particular compressed natural gas.

Abstract:
A system for loading and storing CNG onboard of a ship and for unloading it therefrom comprises CNG loading facilities for loading CNG on board of the ship, CNG storage facilities for storing the loaded CNG on board of the ship at nominal storage pressure and temperature, and CNG unloading facilities for unloading CNG to a delivery point. The delivery point requires the unloaded CNG to be at delivery pressure and temperature generally different from the storage pressure and temperature. Thus, the CNG unloading facilities comprise a CNG heater for heating the to-be-unloaded CNG prior to unloading, and a lamination valve for allowing the to-be-unloaded CNG to expand from its storage pressure to the delivery pressure. A compressor may also be provided to compress CNG that would not otherwise be spontaneously delivered.

Abstract:
An inspectable pressure vessel (10) for containing a fluid such as CNG, the vessel having a generally cylindrical shape over a majority of its length, at least one opening for gas loading and offloading and for liquid evacuation, at least one stainless steel layer as a first layer (100) for being in contact with the fluid when the fluid is contained within the vessel, the first layer being made of low-carbon stainless steel, and a further external composite layer (200) made of at least one fiber-reinforced polymer layer that will not be in contact with the fluid when the fluid is contained within the vessel.
