A method and apparatus fueling vehicle with gaseous fuel includes storage vessels, dispensing sub-stations and a controller. The storage tanks or vessels can be at different pressures. The plurality of dispensing sub-stations each include a dispensing hose and a control valve. Each dispensing sub-station is in controllable fluid communication with the storage vessels so that fluid can flow from the storage vessels through the dispensing sub-station to a vehicle tank. A dispensing hose, and a control valve of the dispensing sub-stations are in the fluid flow paths. The controller receives feedback indicative of a filling parameter from the dispensing sub-stations, and provides control signals to the control valves of the first and second dispensing sub-station to implement one or more desired fill schemes.

A method for replenishing the supply of cryogenic liquid from a storage tank (2) includes: pressurizing a container (14) with cryogenic gas at a first pressure, said container having passing through it a first cryogenic fluid flow line referred to as the cold line and a second cryogenic fluid flow line referred to as the hot line, passing cryogenic liquid at a second pressure through the cold line (12), and supplying the container (14) with cryogenic gas at least partially from cryogenic liquid pumped from the storage tank (2) and vaporized. A device is also provided for the method hereinabove.

A dispensing assembly for a pressure dispense package includes a connector having separate and distinct liquid and extraction conduits, and having a pressurization gas conduit. A liner fitment adapter may include a longitudinal bore to receive a probe portion of a connector defining a liquid extraction conduit, and may include a lateral bore to enable removal of gas. Insertion of a connector into a dispensing assembly simultaneously makes fluidic connections between (a) a gas extraction conduit and a dispensing volume; (b) a liquid extraction conduit and the dispensing volume, and (c) a pressurization gas conduit and a space to be pressurized within a pressure dispense vessel.

The method for producing a filled container of the present invention includes: providing a metal storage container, at least an inner surface of which is formed of a manganese steel and in which the inner surface has a surface roughness R.sub.max of 10 m or less; performing fluorination by bringing the inner surface of the storage container into contact with a gas containing at least one first fluorine-containing gas selected from the group consisting of ClF.sub.3, IF.sub.7, BrF.sub.5, F.sub.2, and WF.sub.6 at 50 C. or lower; purging the inside of the storage container with an inert gas; and filling the inside of the storage container with at least one second fluorine-containing gas selected from the group consisting of ClF.sub.3, IF.sub.7, BrF.sub.5, F.sub.2, and WF.sub.6.

The invention relates to an apparatus for transferring flammable, hazardous and/or cryogenic fluids, comprising a first coupling part and a second coupling part having a connecting and locking mechanism in order to establish a connection to the first coupling part by connecting contact surfaces comprising sealing devices, so that charge equalization can be established. Furthermore, the invention relates to a method of operating an apparatus for transferring flammable, hazardous and/or cryogenic fluids into or out of a mobile, transportable or stationary storage device such that at first charge equalization is established before the transfer process begins.

A pressure control system includes at least one tank storing a mixture of oxygen and nitrogen. The system further includes a first branch of a pressure control line configured to transport a first portion of the mixture of oxygen and nitrogen to a pressurized enclosed volume. The system also includes a second branch of the pressure control line configured to transport a second portion of the mixture of oxygen and nitrogen to at least one flight suit removably coupled to the second branch.

The invention relates to a method for the leakage-proof storage of liquefied chlorine under increased pressure in pressure tanks, in which up to 20 wt. % polyvinyl chloride (PVC) or chlorinated polyvinyl chloride (cPVC) is placed in the pressure tank prior to filling the pressure tank with liquefied chlorine.

A method for releasing a fluid from a pressure vessel assembly, the method including the steps of providing: a pressure vessel; a piezo electric device; and an electric field generator; arranging the piezo electric device in a sealed relationship with a part of the pressure vessel, thereby providing the pressure vessel assembly, providing a fluid contained within the pressure vessel assembly under pressure, and using the electric field generator to apply an electric field to the piezo electric device, such that the piezo electric device fails, thereby releasing the fluid from the pressure vessel assembly.

A mixture and method of creating the mixture includes mixing hexachloroethane, stannous oxide, and aluminum together. The mixture may be loaded into at least one canister.
