摘要:
A fluid storage and dispensing apparatus including a fluid storage and dispensing vessel having a rectangular parallelepiped shape, and an integrated gas cabinet assembly including such fluid storage and dispensing apparatus and/or a point-of-use ventilation gas scrubber in the vented gas cabinet. By the use of physical adsorbent and chemical sorbent media, the gas cabinet can be enhanced in safety of operation, e.g., where the process gas supplied from the gas cabinet is of a toxic or otherwise hazardous character.

A storage tank for storing liquids on the seafloor in a subsea environment is disclosed. The storage tank includes a protective enclosure having a removable cover. The storage tank has at least one compartment therein within which is a container including an outer flexible bladder and an inner flexible bladder within the outer flexible bladder. The inner flexible bladder is capable of containing an inner liquid. The space between the inner flexible bladder and the outer flexible bladder is capable of containing an outer liquid. The inner flexible bladder has a liquid inlet capable of connecting to a source of the inner liquid. The inner flexible bladder has a liquid outlet capable of connecting to a line for conveying the inner liquid to a desired location. The storage tank further includes a recirculation loop for circulating the outer liquid in the space between the inner flexible bladder and the outer flexible bladder. A system for managing liquids in an offshore environment is disclosed, the system using the storage tank, a first conduit connected to the inner flexible bladder liquid inlet of the storage tank for supplying the inner liquid from a topside location, a second conduit connected to the inner flexible bladder liquid outlet, and a pump connected to the second conduit for pumping the inner liquid to a desired pressure for conveying the inner liquid to a desired location.

A support structure of a ship tank includes: a curved surface facing an outer peripheral surface of a horizontal type cylindrical tank; and a pair of support units supporting the tank on the curved surface. Each of the support units includes: a plurality of cylindrical elements arranged in a circumferential direction of the tank such that an axial direction of each of the cylindrical elements coincides with a radial direction of the tank; a plurality of inner members each holding an end portion of a corresponding one of the cylindrical elements at the tank side; and a plurality of outer members each holding an end portion of a corresponding one of the cylindrical elements at an opposite side to the tank. The inner members are fixed to the tank. The outer members of one of the support units are configured such that displacement of the outer members in an axial direction of the tank relative to the curved surface is restricted. The outer members of the other one of the support units are configured to be slidable on the curved surface in the axial direction of the tank.

A liquefied gas system and method can supply gas from a liquefied gas container more efficiently by using an external stabilizing device. The liquefied gas is located under its own vapor pressure in the lower portion of the container. As the vapor is withdrawn from the container at ambient pressure, the liquid evaporates at an equivalent rate to account for the decrease in pressure. The stabilizing device surrounding the liquefied gas container efficiently transfers the ambient external heat to the liquid thus allowing more liquefied gas to be vaporized.

A support assembly mounted on the roof of a tank, comprising a support block (1), a base plate (4) between the support block (1) and the tank, and guiding brackets or rails (2) joined to a structure above the tank characterized in that each of the brackets or rails (2) comprise a face turned towards a cooperating face of the support block, the face of the bracket or rail and the cooperating face of the support block (1) are inclined at an angle, said angle depending on the width and height of the support (1).
摘要:
A container that provides for control of fluid flow in the event of a failure of the container is disclosed. In accordance with embodiments of the present invention, a container is presented that includes a container wall; and one or more flow impeding structures coupled to the container wall, wherein at least one of the one or more flow impeding structures is a multi-sheet layer that deforms to impede flow in a failure of the container wall. In some embodiments, the multi-sheet layer includes cavities formed between individual sheets.

摘要:
A tank mounting technique of the invention effectively responds to a variation in size of a high-pressure tank T in its longitudinal direction and allows positioning of the high-pressure tank T around its longitudinal axis. A tank receiving recess 110 provided below a vehicle platform F has a pair of a front inclined surface 112F and a rear inclined surface 112R arranged to face each other across a concave groove 114. A side face of the high pressure tank T is brought into contact with both the inclined surfaces 112F and 112R. An end face of a tank positioning groove TVS formed on the high pressure tank T is brought into contact with a contact structure 121 of a tank edge bracket 120. This arrangement enables the high-pressure tank T to be positioned in a vehicle vertical direction and a vehicle front-back direction, as well as in the tank longitudinal direction (in a vehicle width direction). The tank positioning groove TVS is aligned with a notch 122 formed in the tank edge bracket 120 to specify a rotational position of the high-pressure tank T around its longitudinal axis.
摘要:
A lightweight carbon fiber air/gas supply vessel storing high pressure air/gas. The air/gas supply vessel output is controlled by an adjustable pressure reduction valve which varies output pressure from very high to low pressure levels. An alternative multi-valve system uses a first pressure reduction valve to reduce output pressure from the very high levels in the air/gas supply vessel to an intermediate pressure level, and a second pressure reduction valve that reduces the air/gas pressure from the intermediate level to a fine tunable low pressure level. In both embodiments, the output of the last pressure reduction valve used is connected to a high pressure cable which in turn uses a standard universal fitting which can be coupled to most pneumatically powered equipment. Additional high pressure reservoir vessels can be used to replenish the lightweight air/gas supply vessel when its supply of air/gas is depleted.
摘要:
A pressure vessel for holding a pressurized fluid such as compressed natural gas ("CNG") includes two end cells and zero or more interior cells. The cell geometry ensures that the cells meet one another at tangential circular surfaces, thereby reducing the tendency of adjacent cells to peel apart. A web secured about the cells includes two sheets that are tangent to the cells. Unused volumes between the cells and the web contain wedges of foam or rubber. A valve provides fluid communication between the interior of the pressure vessel and a pressurized fluid line. The filled weight of one pressure vessel does not exceed the filled weight of a conventional gasoline tank that occupies substantially the same space as the pressure vessel. The pressure vessel may be configured with exterior recesses for engaging conventional gasoline tank straps.
