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 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 concerns a light weight composite pressure container for fluids adapted to hold fluids under both high and low pressures, such as H 2 , industrial gases, CNG (compressed natural gas) and LPG (liquefied petroleum gas), as well as a method of manufacturing the same.
Abstract:
The invention provides a hydrocarbon processing vessel (100) comprising a plurality of first storage tanks (20) arranged on the starboard side of the longitudinal mid-plane (12), a plurality of second storage tanks (22) arranged on the port side of the longitudinal mid-plane, and in symmetrical side-by-side arrangement with the plurality of first storage tanks, and at least one longitudinal bulkhead (24) extending along the mid-plane and located between adjacent first and second storage tanks. Preferably the bulkhead extends from the base (8) of the hull (2) to the deck (10), which deck is supported by the bulkhead. In an embodiment the bulkhead comprises a first and a second bulkhead (26,28) defining a passageway therebetween.
Abstract:
The present disclosure teaches apparatuses, systems, and methods for improving energy efficiency using high heat capacity materials. Some embodiments include a phase change material (PCMs). Particularly, the systems may include a re-gasification system, a liquefaction system, or an integrated system utilizing a heat exchanger with a regenerator matrix, a shell and tube arrangement, or cross-flow channels (e.g. a plate-fin arrangement) to store cold energy from a liquefied gas in a re-gasification system at a first location for use in a liquefaction process at a second location. The regenerator matrix may include a plurality of PCMs stacked sequentially or may include a continuous phase material comprised of multiple PCMs. Various encapsulation approaches may be utilized. Reliquefaction may be accomplished with such a system. Natural gas in remote locations may be made commercially viable by converting it to liquefied natural gas (LNG), transporting, and delivering it utilizing the disclosed systems and methods.
Abstract:
A method and apparatus for unloading natural gas (NG), including gasifying liquid and/or compressed NG using the latent heat of water and propane, and/or storing liquid or compressed NG gas in a storage cavern system that utilizes a buffer layer to prevent hydrating the NG gas, the storage cavem system being configured such that the NG may be forced out of a first storage chamber by increasing the amount of brine in a second chamber to displace a buffer fluid located therein such that the displace buffer fluid enters the first storage chamber and displaces the NG, as well as the processes for compressing, chilling and/or liquefying quantities of LNG and transporting those volumes to markets for redelivery.

Abstract:
An off-shore liquefied natural gas structure may receive, store, and process liquefied natural gas from carriers. Multiple pipelines may be coupled to the structure to export processed natural gas onshore. A structure may be a gravity base structure. A structure may allow direct mooring with carriers. Living quarters, flare towers, and export line metering equipment may be included on the structure.
