Abstract:
A composite pressure vessel, comprising: a liner assembly, further comprising: a liner; at least one of a polar boss and a blind boss; and a shell, further comprising: at least one layer of a filament wrap continuously disposed around at least a substantial portion of the liner assembly, wherein the liner assembly and the filament wrap combined have a non-homogenous support profile; and at least one fiber segment locally disposed on an area of the liner assembly and the at least one layer of a filament wrap that may be more susceptible to rupture than other areas of the liner assembly, according to the non-homogenous support profile. Complementary pairs of fiber segments and/or hoops may be configured to address a non-homogenous stress distribution profile of the composite pressure vessel.
Abstract:
Compressed hydrogen gas can be stored and transferred in hollow structures that include at least one porous metal, in order to protect one or more surrounding layers from being damaged by diffusive flux of hydrogen gas. The masses of hydrogen gas that enter the layer(s)/interlayer(s) of the porous metal(s) are removed from the interconnected pore space in the layer(s)/interiayer(s) of the porous metal(s) to ensure that the pressure(s) of the hydrogen gas remain(s) low-generally less than or equal to one atmosphere. When the structure that holds compressed hydrogen gas is a cylindrical pressure vessel, pipe or pipeline, a technique known as "C-forming" can be used to create a wall containing at least one layer of a porous metal.
Abstract:
A cryogenic-capable high pressure container which combines the use of cryogenic-capable high pressure vessels and ultra-thin thermal barrier(s) having a thickness less than about 5 mm because of the reduced thermal requirements of the container from flexible usage, for maximizing storage space. Additional increase in storage capacity may be obtained by using conformable pressure vessels having box-shaped configurations for further maximizing storage space and capacity. Further efficiencies may be achieved by nesting high pressure vessels inside box-shaped lower pressure vessels to utilize for storage the interstitial spaces form between them.
Abstract:
La invención se refiere a un contenedor incorporando en su interior un arrollamiento de un tubo o manguera, adecuada en sección, longitud y disposición, preferentemente de material plástico o similar, aunque es posible su fabricación en otros materiales, montándose en serie con dicho arrollamiento una válvula de interrupción para regular la entrada del gas y otra válvula de interrupción para regular la salida de gas, situándose estas válvulas fuera del contenedor, junto con los medios de seguridad adecuados, tales como válvulas de retención y presostatos de máxima y mínima, pudiendo o no trabajar adosada a un equipo de producción, por ejemplo, de gases combustibles o su utilización como contenedor para el transporte del elemento o elementos que contengan. Todo ello protegido con un envoltorio adecuado para los diversos usos a que se destine.
Abstract:
Cryogenic tank intended for containing a cryogenic fluid, in particular a space launcher tank intended to contain a cryogenic propellant, comprising a wall (1 ) defining a storage volume for the cryogenic fluid, characterized in that it includes at least one partition (2) located in the storage volume, said partition (2) defining an upper volume (VS) and a lower volume (Vl) for the fluid in the tank (1) communicating via at least one opening (3) formed in the partition (2), in order, on the one hand, to allow the liquid to flow under gravity from the upper volume (VS) into the lower volume (Vl) and, on the other hand, to prevent the fluid from rising from the lower volume (Vl) into the upper volume (VS) under the action of acceleration forces.
Abstract:
A storage tank containment system including a cubic-shaped tank having an outer shell having cylindrical walls and an internal cross brace interconnecting the cylindrical walls for the efficient storage and transportation of large quantities of fluid, for example, liquid natural gas.
Abstract:
The present invention provides an extended spherical LNG storage tank, installed on an LNG tanker, and a method for manufacturing the same, in which the junctions between a connection tank part and upper and lower tank parts are configured as smooth parts, thus increasing the LNG storage capacity of the tank and mitigating stress concentration on the junctions, and the connection tank part is constructed by integrating a plurality of plates into a single structure, thus increasing work efficiency while fabricating the connection tank part and thereby enabling quick and easy production of the LNG storage tanks. In the extended spherical LNG storage tank, which includes the upper and lower tank parts, each having a predetermined radius of curvature R, and the connection tank part provided between the upper and lower tank parts so as to increase the LNG storage capacity of the tank, the connection tank part is defined by a circular arc or a parabola C3, which is circumscribed with two circles Cl and C2, which define the upper tank part and the lower tank part, respectively, outside the two circles Cl and C2.
Abstract:
Von einem Außenbehälter (1) umgebener, zur Aufnahme einer kryogenen Flüssigkeit, insbesondere eines Kraftstoffes, dienender Innenbehälter (3) in abgeflachter Bauweise, insbesondere Innentank für ein Straßenfahrzeug, gekennzeichnet durch die Kombination folgender Merkmale: einen sich längs erstreckenden einstückigen Grundkörper (4) mit einer Deck- (5) und einer Basiswand (6), die mit sich ebenfalls längs erstreckenden Seitenwänden (7) verbunden sind, und mit mindestens zwei längs verlaufenden, die Basiswand (6) mit der Deckwand (5) verbindenden im Wesentlichen geraden Stegen (9) zur Bildung mindestens einer zwischen den Stegen angeordneten sich längs erstreckenden Kammer (10), die sich über die gesamte Länge des Grundkörpers (4) und jeweils von der Basiswand (6) zur Deckwand erstreckt (5), wobei die sich längs erstreckende Kammer zwischen dem Stegen eine vorbestimmte Breite aufweist, und zumindest zwei Kappen (11), die die zwei offene Enden des Grundkörpers (4) jeweils peripher dicht verschließen, und wobei die Deck- und/oder Basiswand jeweils gegenüber einer planen Referenzdeck- und/oder Referenzbasiswand eine Aufwölbung mit einem mittig zwischen den Stegen jeweils zwischen der inneren Kontur der Deck- und/oder Basiswand und der planen Referenzdeck- und/oder Referenzbasiswand gemessenen Abstand von weniger als 30% der Breite der Kammer aufweist.
Abstract:
A gas storage system (1) comprises a tank (10), having a tank gas outlet (28), and a multitude of gas emitting entities (20) encapsulated by the tank (10). The gas emitting entities (20) are arranged for providing a gas volume, which when released from said gas emitting entities, is considerably larger than a volume of the gas emitting entities (20) themselves. The gas emitting entities (20) are freely contained in the tank (10), i.e. there are no gas conduits or electrical connections to the tank (10). The tank (10) has a sealable opening (18) suitable for removal or insertion of the gas emitting entities (20) and the gas emitting entities (20) have a respective gas release device, which is operable as a response on a stimulation signal. A volume (14) surrounding the gas emitting entities (20) inside the tank (10) is the sole fluid connection between an opening of the gas release device and the tank gas outlet (28). Methods for storing and releasing gas are also presented.
