Abstract:
- La présente invention concerne un système de stockage d'énergie sous forme d'air comprimé, caractérisé en ce qu'il est constitué par un ensemble de tubes aciers (1), droits ou enroulés, assemblés pour former un volume de stockage disposé en surface, ou en sub-surface, l'assemblage étant enfermé dans une enveloppe isolante thermiquement (2).
Abstract:
The present invention relates to a covering for a gas storage (100). The covering comprises an exterior membrane (101) for at least partially enveloping a storage volume (Vs) of the storage (100), wherein the exterior membrane (101) is made of an elastomeric material, so that a shape and an area size of the exterior membrane (101) is adaptable to a pressure of the gaseous medium in the storage volume (Vs). The storage (100) further comprises a support structure mounted over the exterior membrane (101) in such a way that a) if a first pressure value in the storage volume (Vs) is reached, a first portion (111) of the exterior membrane (101) contacts the support structure in a force transmitting manner and a second portion (112) of the exterior membrane (101) is contact-free with the support structure, and b) if a critical pressure value storage volume (Vs) is reached, at least one of the support structure and the exterior membrane (101) fails, wherein if the critical pressure value in storage volume (Vs) is reached, the second portion (112) is expandable such that a contribution (Va) to the storage volume (Vs) of at least 10% in comparison to the volume of the storage volume (Vs) with the first pressure value is generated.
Abstract:
A LNG storage container (50) includes: an inner shell (51) made of a metal withstanding a low temperature of the LNG and configured to store the LNG inside; an outer shell (52) made of a steel withstanding an internal pressure of the inner shell (51) and configured to enclosing the outside of the inner shell such that a space is formed between the inner shell (51) and the outer shell (52); and a heat insulation layer part (53) installed in the space between the inner shell (51) and the outer shell (52) and configured to reduce a heat transfer. Accordingly, it is possible to efficiently store LNG or PLNG pressurized at a predetermined pressure and supply the LNG or PLNG to a consumption place, to reduce manufacturing costs by minimizing the use of a metal having excellent low temperature characteristic, to reduce a thickness of an inner container by minimizing a difference between the internal pressure and external pressure of the inner container, thereby manufacturing the container (50) at low cost, to satisfy consumer's various demands, and to ensure diversity in kinds and sizes of container carriers. Furthermore, it is possible to endure various utilizations according to characteristics of cargos, such as pre-processed natural gas, non-pre-processed natural gas, and refined natural gas. Due to the reduction of the liquefaction process, equipment costs and processing costs may be reduced. Sloshing load, which may occur during transportation of liquid goods, is reduced or negligible.
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:
The present invention relates to an independent vessel tank system for storing liquid gas. The system comprises a first tank member (1), a second, cylindrical tank member (2) connected to the first tank member (1) and a third tank member (3) connected to the second tank member (2), where the first, second and third tank members (1, 2, 3) provide a tank device for the liquid gas. A first supporting device (5) is provided between the third tank member (3) and a hull of the vessel, for supporting the weight of the tank device. A second supporting device (4) is at least partially provided along the periphery of the tank device, for supporting the tank device to the hull of the vessel.
Abstract:
The present invention comprises a tank for liquefied gases or a so-called cryogenic tank (1) with a tank bottom structure (10) and a tank wall structure (11) arranged around a circumference of said tank bottom structure (10), said tank bottom structure (10) provided with a tank bottom hub (2) adapted for being held by a bottom hub retainer (20) on a tank support structural floor (23). The tank is simple to install, cheap in production and handles in an improved manner forces acting on it.
Abstract:
Die Erfindung betrifft einen doppelwandigen Druckbehälter, zur Speicherung von kryogenem Kraftstoff in einem Kraftfahrzeug, dessen innerer Druckbehältermantel aus ersten Behälterteilen und dessen äußerer Behältermantel aus zweiten Behälterteilen zusammengesetzt ist, die jeweils mindestens in einer zu deren Mittellängsachse parallelen oder schiefen Ebene so abgeschnitten und an den Schnittstellen so miteinander verbunden sind, dass der innere Druckbehältermantel mindestens zwischen den ersten Behälterteilen mindestens eine konkave Einwölbung besitzt. Des weiteren besitzt der den inneren Druckbehältermantel umgebende äußere Behältermantel nach innen gerichtete Abstützeinrichtungen, von denen sich jeweils eine in eine konkave Einwölbung des inneren Druckbehältermantels hinein erstreckt. Die Erfindung ist dadurch gekennzeichnet, dass die konkave Einwölbung des inneren Druckbehältermantels jeweils von mindestens einem Zugband überspannt ist und dass die Abstützeinrichtungen des äußeren Behältermantels an dem jeweiligen Zugband anliegen.
