Patent number: 6938654Abstract: System for the transportation and storage of a product which comprises a tank including cylindrical wall section and two ends, wherein the cylindrical wall section and two ends define a cylindrical tank periphery, and wherein the tank periphery has an interior and an exterior. The system utilizes a valve box that includes 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. One or more process valves are disposed in the valve box, wherein each valve has a first and a second end, wherein each first end is 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. A purge valve and pressure measurement means are installed in fluid communication with the valve box.Type: GrantFiled: October 6, 2003Date of Patent: September 6, 2005Assignee: Air Products and Chemicals, Inc.Inventors: Vladimir Yliy Gershtein, Robert William Ford, John Frederick Cirucci

Patent number: 6814092Abstract: 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.Type: GrantFiled: June 27, 2003Date of Patent: November 9, 2004Assignee: Air Products and Chemicals, Inc.Inventors: Anthony J. Lachawiec, Jr., Vladimir Yliy Gershtein, Ronald Martin Pearlstein, Robert William Ford

Patent number: 6637469Abstract: 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.Type: GrantFiled: March 19, 2002Date of Patent: October 28, 2003Assignee: Air Products and Chemicals, Inc.Inventors: Steven W. Hoffman, Vladimir Yliy Gershtein, Alexandre De Almeida Botelho, Robert William Ford, Paul David Kottler

Patent number: 6614009Abstract: 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.Type: GrantFiled: September 28, 2001Date of Patent: September 2, 2003Assignee: Air Products and Chemicals, Inc.Inventors: Vladimir Yliy Gershtein, Alexandre De Almeida Botelho, Bruce H.

Patent number: 6514564Abstract: A dynamic blending gas delivery system and method are disclosed. A blended gaseous mixture produced in accordance with the method is used in chemical vapor deposition tools or similar process tools. One embodiment is a multi-step method for processing a plurality of fluids to form a blended gaseous mixture and supplying the blended gaseous mixture to a distribution header from which the blended gaseous mixture is delivered to at least one tool. The first step is to supply a first fluid. The second step is to heat the first fluid to a temperature where at least some portion of the first fluid is a vapor. The third step is to superheat the vapor portion of the first fluid to a temperature sufficient to avoid condensation of the blended gaseous mixture delivered to the at least one tool. The fourth step is to supply a second fluid.Type: GrantFiled: March 6, 2001Date of Patent: February 4, 2003Assignee: Air Products and Chemicals, Inc.Inventors: Alexandre de Almeida Botelho, Thomas Anthony Del Prato, Robert William Ford
