Abstract:
A low-cost getter material comprising palladium and manganese oxide and methods of making the same. A tank including said getter material, and a method of removing hydrogen gas.
Abstract:
A system for dispensing a cryogenic liquid includes a storage tank containing a supply of the cryogenic liquid and a metering chamber. A liquid inlet line is in communication with the storage tank and the metering chamber so that the metering chamber receives cryogenic liquid from the storage tank. A meter run is in communication with the metering chamber and includes a metering element, a dispensing line and a dispensing valve. A stabilizing column is positioned within the metering chamber and includes vertically spaced openings. Vertically spaced first and second pressure sensors are in communication with the interior of the stabilizing column. A controller is in communication with the metering element, the first and second pressure sensors and the dispensing valve.
Abstract:
A cryogenic fluid delivery manifold system includes a plurality of cryogenic supply tanks. A liquid flow manifold permits flow of liquid a use device. A vapor pressure manifold is coupled to the supply tanks and to a pusher tank for regulating and/or balancing pressure across the plurality of supply tanks.
Abstract:
An integrated cryogenic fluid delivery system includes a cryogenic liquid tank having an interior, a wall and a geometry. The interior of the cryogenic liquid tank contains a supply of cryogenic liquid. A fuel pickup line is positioned within the interior of the tank and is in fluid communication with a vaporizer so that the vaporizer receives and vaporizes cryogenic liquid from the tank. The vaporizer is positioned outside of the tank and is secured to the wall. The vaporizer also has a shape that conforms with the geometry of the tank.
Abstract:
A system for dispensing a cryogenic fluid includes a bulk tank containing a supply of cryogenic fluid. A heating circuit includes an intermediate tank and a heating device and has an inlet in fluid communication with the bulk tank and an outlet. A bypass junction is positioned between the bulk tank and the inlet of the heating circuit. A bypass circuit has an inlet in fluid communication with the bypass junction and an outlet so that a portion of cryogenic fluid from the bulk tank flows through the heating circuit and is warmed and a portion flows through the bypass circuit. A mixing junction is in fluid communication with the outlets of the bypass circuit and the heating circuit so that warmed cryogenic fluid from the heating circuit is mixed with cryogenic fluid from the bypass circuit so that the cryogenic fluid is conditioned. A dispensing line is in fluid communication with the mixing junction so that the conditioned cryogenic fluid may be dispensed. Warmed cryogenic fluid remaining in the heating circuit after dispensing is directed to the intermediate tank and used to warm cryogenic fluid directed through the heating circuit.
Abstract:
A frangible closure coupling is used with or on pipe of a tank that contains a potentially dangerous fluid, such as liquid natural gas. The closure coupling mitigates the uncontrolled release of fluid from the tank in the event of a rupture of a pipe attached to the tank.
