H05B 302

US Classification:

219486, 219497, 392416, 392394

Abstract:

A high flow rate, transportable, ultra high purity gas vaporization and supply system is provided which includes a vessel suitable for carrying large quantities of a liquefied gas, valves to operate with liquid or gas phases, a loading/unloading unit disposed on the vessel for loading and unloading the liquefied gas to be supplied, and a heater containing heating elements permanently positioned on the vessel to supply energy into the liquefied gas. The heater causes the liquefied gas to be supplied through the loading/unloading unit as a gas. A heater controller is also provided which uses process variables feedback for regulating the heating elements to maintain and regulate gas output.

Abstract:

A process and system for conditioning a bulk container for ultra-high purity liquefied gas. Vapor is generated in the container from a conditioning quantity of the ultra-high purity liquefied gas by imposing a temperature difference on the container so that the vapor condenses when a temperature difference is achieved. The resulting liquid reflux, e. g. , the condensed liquid drips or flows back to the conditioning quantity of the liquified gas, washes or removes contaminants, e. g. , particles, metal and moisture, from the interior surface of the container. A portion of the vapor is vented from the container for reclamation. The used conditioning liquid may also be reclaimed.

Abstract:

A container for holding a solid, liquid and/or gaseous phase product therein and for use within a transportable or stationary support structure. The container maximizes the compressed product volume contained therein and prevents liquid and/or contaminant entrainment during gaseous product delivery from liquid phase product. The system allows for product withdraw when the level is above the delivery valves using, at a minimum, two delivery legs linked by a compartment or housing that connects the delivery point and a container head space via a removable manway.

International Classification:

B65B 104

US Classification:

141 64, 141311 A, 141 86, 137350, 220 15

Abstract:

A system for the transportation and storage of a product comprising a tank including a cylindrical wall section and two ends which define a cylindrical tank periphery, wherein the tank periphery has an interior and an exterior; a recessed valve box including one or more side walls, a bottom wall, and a removable, sealable top cover which can be attached to the one or more side walls to seal the valve box, wherein the valve box side walls are sealably joined to the cylindrical wall section such that the valve box extends through the cylindrical wall section into the interior of the tank periphery and is partially or totally disposed in the interior of the tank periphery; and one or more valves disposed in the valve box. Each valve has a first and a second end, wherein each first end may be connected to a pipe which passes through a wall of the valve box for introducing product into the tank or withdrawing product from the tank, wherein the valves are disposed partially or totally within the tank periphery, and wherein the tank has a rigid framework surrounding the tank and valve box, wherein the framework is attached to and supports the tank, and wherein the framework defines a periphery which encloses the periphery of the tank. The product in the tank can be isolated from the atmosphere surrounding the tank when the valves are closed.

Air Products and Chemicals, Inc. - Allentown PA

International Classification:

F17C 500

US Classification:

62 541, 62537, 417207

Abstract:

This invention relates to an improvement in a process and apparatus for delivering ultra high purity liquid carbon dioxide to a point of use at pressures above ambient without pumping. In the process a high purity carbon dioxide feed in gaseous or liquid form is charged to a vessel and at least partially solidified, i. e. , converted to a solid phase. As the liquid is converted to a solid phase, additional liquid is added until the vessel is at least substantially filled with slush. Once filled, the slush or solid is isochorically heated, i. e. , heated at constant volume whereby the solid phase carbon dioxide is converted to a liquid. Liquid, then, is withdrawn from the vessel at a desired pressure at a rate at which the solid phase carbon dioxide is converted to a liquid.

Abstract:

A vessel for the storage and transportation of bulk volumes of a fluid is described herein and a method for using same. The vessel contains a plurality of dividers that apportion the internal volume into a number of sections. The dividers within the vessel aid in minimizing sloshing of the fluid contained therein during transport. In addition, the dividers optimize the fluid flow pattern thereby allowing for the continuous purge of the vessel without the need for the application of a partial or full vacuum.
