摘要:
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.
摘要:
A system for offloading a compressed fluid from a series of pressure vessels, the system comprising a multilevel piping system and at least one ejector device, the ejector device being for recovering energy from a high pressure fluid stream from a substantially full pressure vessel, and for forced suction of residual fluid from a part offloaded pressure vessel, the multilevel piping system comprising, in use, at least three different pressure levels, including a high pressure line, a medium pressure line and a low pressure line, the high pressure line being intended to supply the said ejector device with the high pressure fluid stream, the medium pressure line being intended for both the forced suction of the residual fluid and mixing with the high pressure line, and the low pressure line being intended for each of mechanical suction of the residual gas not drawn off by the ejector, recompression thereof by means of at least one compression turbomachine, and assisting energy recovery by transferring heat via gas/gas exchangers.
摘要:
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 the 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 supported at, or in cooperation with, its end caps rather than being supported on its longitudinal main body.
摘要:
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.
摘要:
A device in the form of a pressure vessel for use in an application other than a combustible fuel application, the pressure vessel being for storing a fluid at a pressure in excess of 30 bar, and being for connection to a user interface so as to supply the fluid to the user's desired application. The pressure vessel may have one or more composite nozzle integrated in the vessel structure, or it may be either a type 3, 4 or pressure vessel, or a pressure vessel of a design having a lower weight per fluid capacity ratio than both approved type 1 pressure vessels of an equivalent size and approved type 2 pressure vessels of an equivalent size.

摘要:
A device in the form of a pressure vessel for storing or transporting a fuel at a pressure in excess of 30 bar, wherein the pressure vessel has either one or more composite nozzle integrated in the vessel structure or a lower weight per gas capacity ratio than both approved type 1 pressure vessels of an equivalent size and approved type 2 pressure vessels of an equivalent size.
摘要:
A device in the form of a pressure vessel for storing or transporting a fuel at a pressure in excess of 30 bar, wherein the pressure vessel has a ratio of the structural weight of the pressure vessel when empty over the certificated maximum transported fuel weight being in the range of 0.7 to 3.4.
