Abstract:
An underwater carbon dioxide storage facility including a carbon dioxide deposit stored underwater as a clathrate includes a flexible barrier disposed at least partially over the carbon dioxide deposit. The carbon dioxide deposit may be stored in or at the bottom of a body of water.
Abstract:
A cryogenic storage tank comprises a partition that divides a cryogen space into a main storage space and an auxiliary space. A valve disposed inside the cryogen space is associated with a first fluid passage through the partition. The valve comprises a valve member that is actuatable by fluid forces within the cryogen space. A second fluid passage through the partition comprises a restricted flow area that is dimensioned to have a cross-sectional flow area that is smaller than that of a fill conduit such that there is a detectable increase in back-pressure when the main storage space is filled with liquefied gas.

Abstract:
The present invention relates to a tank for pressurised gas composed of multiple cells joined by means of connection plates (P), in which each cell (C) is composed of a tubular body sealed at the two ends by means of two caps (2) and the adjacent cells communicate in pairs through a series of ducts, which comprises one or more radial ducts (5) obtained on the head (2a) of each cap (2), annular ducts (9) that surround the head (2a) of each cap (2) and transversal holes (10) obtained on the connection plates (P) and designed to provide communication between the adjacent pairs of annular ducts (9).
Abstract:
A flat inner container (3), especially an internal tank for a road vehicle, which is surrounded by an outer container (1) and is used for receiving a cryogenic liquid, particularly a fuel. The inner container (3) comprises a combination of the following features: a longitudinally extending monolithic base (4) with a top wall (5) and a bottom wall (6) which are connected to also longitudinally extending sidewalls (7), and with at least two longitudinally extending, substantially straight webs (9) that connect the bottom wall (6) to the top wall (5) so as to form at least one longitudinally extending chamber (10) which is arranged between the webs, extends along the entire length of the base (4) as well as from the bottom wall (6) to the top wall (5), and has a predetermined width between the webs; and at least two caps (11) which tightly seal the two open ends of the base (4) at the periphery; the top wall and/or the bottom wall is/are provided with an arch relative to a planar reference top wall and/or reference bottom wall, the distance of the arch between the inner contour of the top wall and/or the bottom wall and the planar reference top wall and/or reference bottom wall amounting to less than 30 percent of the width of the chamber in the center between the webs.
Abstract:
A pressure vessel is configured such that a plurality of liners 1 are juxtaposed with one another. Each liner 1 includes a tubular trunk 4, and end plates 5 for closing opposite end openings of the tubular trunk 4. Two adjacent liners 1 are integrally connected together via a connection member 2 provided therebetween. The interiors of the integrally connected two adjacent liners 1 communicate with one another via a communication path 3 formed in the liners 1 and in the connection member 2. The ends of connection-member-forming projections 16 provided respectively on the two adjacent liners 1 are butt-joined together, thereby forming the connection member 2. The two adjacent liners 1 have respective through-holes 17 extending from the inner surfaces of the two adjacent liners to the ends of the connection-member-forming projections 16, and the through-holes 17 of the two adjacent liners 1 establish communication therebetween, thereby forming the communication path 3. This pressure vessel can be installed without generation of dead space, can implement a large capacity, and can be reduced in material cost and weight.
Abstract:
The present invention relates to a pressurized package and a method for manufacturing and filling a pressurized package. The pressurized package has an outer container (10) and an inner container (20) situated within the outer container (10). In the outer container (10) a chamber (11) for material (12) to be dispensed is arranged and in the inner container (20) a propellant chamber (21) for propellant (20) is arranged, which are separated from each other in a manner that is impermeable to liquid and gas. The outer container (10) is closed by a cover part (15) on which a valve part (16) is arranged for dispensing the material (12) from the chamber (11) outwards. To improve pressurized packages of this type, a pressurized cartridge (30) containing a propellant (22) is arranged in the inner container (20), and the pressurized cartridge is associated with an opening mechanism (31) for at least one-time opening of the pressurized cartridge (30) to the propellant chamber (21) of the inner container (20). The opening mechanism (31) reacts to filling of the chamber (11) with material (12) to be dispensed.
Abstract:
A multilayered pressure vessel (10) fabricated from at least one single ply sheet of flexible material (100) having an approximate longitudinal midline which divides the material into an inner portion (130) having an inner surface, an outer surface, an edge, a seam allowance, and a width, and an outer portion having an inner surface, an outer surface, an edge, a seam allowance, and a width. The width of the outer portion (120) is greater than the width of the inner portion (140). A primary seam (250) binds the outer portion and the inner portion to the material sheet at the midline proximate the outer portion edge and inner portion edge. The sheet (100) is wrapped into a continuous substantially 720 degree wrap to form a generally cylindrical vessel body having possible multiple fluid passageways, at the election of the user. The primary seam (250) is concealed.
Abstract:
A method of utilizing a divided pressure vessel in a processing system employing a carbon dioxide based solvent includes transferring a first carbon dioxide based treating solution from a first liquid chamber in a divided pressure vessel having a plurality of liquid chambers to a processing vessel, returning the first treating solution from the processing vessel to the divided pressure vessel, transferring a second carbon dioxide based treating solution having a composition different from the first treating solution from a second liquid chamber in the divided pressure vessel to a processing vessel, and returning the second treating solution from the processing vessel to the divided pressure vessel. A divided pressure vessel may allow multiple solvent baths each having a different chemical composition to be stored and/or processed in a single pressure vessel while maintaining the different chemical compositions of the multiple solvent baths. Thus, such divided pressure vessels may provide the improved operational efficiency of a carbon dioxide based system having multiple solvent baths while decreasing the capital costs that may be associated with such systems.
Abstract:
A storage tank for cryogenic liquids incorporates an ullage vessel that provides for an ullage space. The ullage vessel is in communication through an ullage line to a fill line that provides cryogen to a cryogen space. The junction where the ullage line and fill line meet is of a certain cross-sectional area. Downstream of the junction, the fill line is of a greater cross-sectional area than at the junction. This creates a pressure reduction at the junction during filling, which causes a net flow of material from the ullage space over the course of filling. Once the tank is liquid full, causing cryogen to be redirected down the ullage line, the smaller cross-sectional area of the ullage line compared to the fill line causes a reduction in flow of cryogen which is detected by the fill pump causing filling to stop.
