Abstract:
PROBLEM TO BE SOLVED: To provide an extended spherical LNG storage tank and a method for manufacturing the same, in which junctions between connection parts of an LNG storage tanks installed on an LNG carrier and upper and lower tank parts are configured gradually so as to increase the storage capacity of the LNG storage tank, while mitigating a stress concentration phenomenon on the junction, and in which the connection tank part is constructed by connecting a plurality of plate pieces to thus facilitate the manufacturing and working, thereby allowing the manufacturing work of the LNG storage tank to be performed quickly and easily.SOLUTION: The connection tank part 40 is formed of connection of a plurality of the plate pieces with different thickness to an equatorial part 45. The plate pieces are connected so that the pieces become thicker from the upper tank part 20 side the lower tank part 30 side. A plate piece to be connected nearest to the lower tank part among the plate pieces with different thickness is thicker than the lower tank part.
Abstract:
The present disclosure relates to a method of constructing a liquefied gas storage tank on land, which enables rapid and easy construction of walls of a cylindrical storage tank by stacking a plurality of pre-produced unit-wall structures (10) to overlap one another. The method includes: producing unit-wall structures (10) made of concrete and each having iron rods (11) arranged lengthwise and breadthwise therein, stacking the unit-wall structures (10) in a cylindrical arrangement, and connecting the unit-wall structures (10) adjacent in vertical and lateral directions to each other to form a wall of the storage tank.
Abstract:
Pressure vessel assembly for a pressurized fluid system, comprises an enclosed outer casing, at least one internal tube extending within the casing, at least one fluid accumulator disposed within the at least one internal tube, and at least one cooling passage provided within the at least one internal tube and defined by a clearance between the at least one hydraulic fluid accumulator and the at least one internal tube. The pressure vessel assembly further includes a fluid storage compartment formed between the outer casing and the at least one internal tube. The fluid storage compartment is at least partially filled with a working fluid. The pressurized fluid system also includes a cooling fan allowing forced airflow through the cooling passage for forced cooling of the at least one hydraulic fluid accumulator and the working fluid in the storage compartment of the pressure vessel assembly.
Abstract:
The present invention relates to a metal nozzle boss provided with a sealing device, which has highly improved tightness and is combined with a plastic liner of a composite vessel used as a high-pressure vessel. The metal nozzle boss uses an elastic seal ring and a tightening piece in the plastic liner, so that the nozzle boss reliably seals the junction of the nozzle boss and the liner and prevents gas leakage from the vessel. The blade part of the nozzle boss has a dovetail-shaped locking groove, with locking ridges formed in the locking groove. Thus, when the plastic liner is produced by injecting molten resin into the locking groove, the plastic liner is securely combined with the metal nozzle boss. The composite vessel having the metal nozzle boss can be used as a fuel tank for natural gas vehicles or a hydrogen tank for fuel cell vehicles.
Abstract:
A compressed gas storage system includes a gas tank formed for storing therein compressed gas, a gas discharge path provided in the gas tank, a solenoid valve connected to the gas discharge path and disposed in an interior of the gas tank for controlling the flow of compressed gas that goes out of the gas tank and a control unit to which the solenoid valve is connected. An outer circumferential surface of the solenoid valve is covered with a cover, so that a space defined between the cover and the outer circumferential surface is made to communicate with the gas discharge path to thereby form a gas flow path. A heat transfer fin is formed on an inner circumferential surface of the cover in such a manner as to extend radially inwardly, so as to be brought into contact with the outer circumferential surface of the solenoid valve.
Abstract:
PROBLEM TO BE SOLVED: To provide an apparatus for storage and liberation of a gas such as ultra high pressure compressed hydrogen in a cartridge including a lot of microcylindrical arrays. SOLUTION: A housing 11 forming a chamber 13 is included which has a cartridge 14 including an array 143 of hollow microcylinders forming cavities for storage of a compressed gas. Each microcylinder 143 is sealed with a plug 147 made of an easily meltable alloy. A gas liberating tool 15 liberating the gas from the cartridge 14 to the chamber 13, and a control system 16 coupled to a discharge valve are included. A system and method are provided for filling the cartridge 14 having the array 143 of the hollow microcylinders having open ends. The filling includes: putting the cartridge 14 into a chamber of an autoclave; compressing the gas in the chamber, and thereby providing permeation of the gas into the cavities of the microcylinders through the open ends. Thereafter, the open ends are sealed with the plugs 147 made of an easily meltable alloy. COPYRIGHT: (C)2009,JPO&INPIT
Abstract:
Fluid storage and dispensing systems, and processes for supplying fluids for use thereof. Various arrangements of fluid storage and dispensing systems are described, involving permutations of the physical sorbent-containing fluid storage and dispensing vessels and internal regulator-equipped fluid storage and dispensing vessels. The systems and processes are applicable to a wide variety of end-use applications, including storage and dispensing of hazardous fluids with enhanced safety. In a specific end-use application, reagent gas is dispensed to a semiconductor manufacturing facility from a large-scale, fixedly positioned fluid storage and dispensing vessel containing physical sorbent holding gas at subatmospheric pressure, with such vessel being refillable from a safe gas source of refill gas, as disclosed herein.
Abstract:
A system and method for controlled rate freezing and storage of thermolabile substances. The system includes a storage unit for receiving product stored within a bag and an overlying protective canister associated with a robotic arm and reading device which places the canister in the preserving environment. A control system, driven by a computer monitors the ingress, egress and storage location and particularized profiles of the articles being placed in storage.
