The invention relates to a liquefied-fluid storage tank including a storage wall the inner surface of which defines a storage volume for liquefied fluid, the tank including an exchanger for cooling the fluid contained in the tank in particular to condense vapors of said fluid. The invention is characterized in that the cooling exchanger includes a body of metal, in particular aluminum, in which at least one pipe of a coolant circuit is integrated in order to cool said body and in that the body is in contact with and attached to the outer surface of the storage wall.

A cryogenic system as well as a method of generating a pressurized, sub-cooled mixed-phase cryogen and a method of delivering such a cryogen to a cryoprobe are disclosed. In an embodiment, the cryogenic system includes a reservoir containing a liquid cryogen and a sub-cooling coil immersed in the liquid cryogen. The cryogen is supplied to the sub-cooling coil and is cooled under pressure to produce a pressurized mixed phase cryogen within the sub-cooling coil. This pressurized mixed phase cryogen is provided via supply line to a cryo-device for use.

An installation for supplying gas provided with an insulating chamber including a rear wall and two side wall as well as a door that pivots about a vertical axis in order to allow opening and closing of the chamber, the installation including two multifunctional blocks that house a fluid circuit and are attached to the rear wall inside the chamber.

A fluid supply package comprising a pressure-regulated fluid storage and dispensing vessel, a valve head adapted for dispensing of fluid from the vessel, and an anti-pressure spike assembly adapted to combat pressure spiking in flow of fluid at inception of fluid dispensing.

The present invention provides a lightweight high pressure vessels that are made from a liner or a liner housing that is overwrapped with a composite material. Unlike conventional high pressure vessels, the lightweight high pressure vessel of the invention includes a liner that comprises a plurality of liner sections without using welding or crimping. In particular, the lightweight high pressure vessels of the invention include a plurality of elements that are combined to form a liner housing and a composite overwrap that provides structural and mechanical strength to maintain integrity of the high pressure vessel. In one particular embodiment, the high pressure vessel of the invention is a diaphragm accumulator.

A method for condensing argon can include two flow streams interacting with each other in a heat exchanger found within a cold box: a stream of gaseous argon enters the heat exchanger to be cooled down below its liquefaction point by a stream of pressurized liquid nitrogen entering the heat exchanger. While passing through the heat exchanger, gaseous argon is gradually cooled down until it is condensed into liquid, flowing by gravity to the nearby liquid argon storage tank.

An apparatus for condensing argon can include cold box, which is preferably sealed and largely maintenance free, where all instruments and valves requiring routine maintenance are to be located outside, a nitrogen separator disposed within the cold box, a heat exchanger disposed within the cold box, the heat exchanger is configured to condense a gaseous argon stream against a pressurized liquid nitrogen stream. The cold box is elevated as compared to an argon storage vessel, such that the condensed argon stream can flow to the argon storage vessel without the need for a pump.

A safety cap for a pressurised gas storage vessel is disclosed comprising a valve that is movable between: (i) a first position in which an entrance port and anti-recoil apertures are in fluid communication such that gas is able to flow out of the safety cap through the anti-recoil apertures; and (ii) a second position in which the gas is unable to exit the safety cap through the anti-recoil apertures and in which the entrance port is in fluid communication with an exit port such that gas is able to flow from the entrance port, through the exit port and out of the safety cap.

A system to convert and dispense pressurized gas(es) of cryogenic liquids of gas(es), and systems and methods to efficiently convert liquid natural gas (LNG) to compressed natural gas (CNG) and low pressure natural gas (NG) and other cryogenic liquids of gas. The system requires one dedicated pressure vessel of horizontal and vertical elements at the dispensing location to convert, retain, store, and dispense multiple pressures of gas from a cryogenic liquid supply such as a non-dedicated high pressure cryogenic personal supply tank. The system efficiently modifies and controls parameters of volume, pressure, and temperature in conversion scale to retain all converted product under human control to dispense without process required waste for use in commercial, industrial, and in particular single family residential applications and service can be accomplished by pickup truck and trailer, where semi trucks, big rig trucks and process pollution are not welcome.

Pressurized gas bottles with integrated valves, in which a plurality of functional supports are integrated in an extraction unit, are equipped with complex fall protection means. Moreover, in such a valve, a new approval procedure is carried out for the entire valve in the event of multiple modifications, for example when supplementing it with an additional function. In order to reduce the effort associated with this, an extraction fitting for a pressurized gas bottle is provided with a modular design, wherein a base module comprising the shut-off member and a fall protection device securing the shut-off member complies with legal requirements regarding fall protection and the shut-off device of the pressurized gas bottle. All further functionalities of the extraction fitting are integrated in at least one additional module, which is connected to the base module in a fixed but removable manner and without impairing the fall safety.
