Patent number: 7201018Abstract: The invention relates to a process and apparatus for delivering an ultra high purity fluid comprising at least one component to a point of use at a required pressure without mechanical pumping. In one embodiment, a high purity feed comprising at least one component in gaseous or liquid form is charged into a vessel and at least partially converted to a solid phase source. As the feed is converted to a solid phase source, additional feed may be added until the vessel is at least substantially filled with a solid phase source or slush. Once filled, the solid phase source or slush may be isochorically heated whereby the solid phase source is converted to a product at an elevated pressure.Type: GrantFiled: January 9, 2004Date of Patent: April 10, 2007Assignee: Air Products and Chemicals, Inc.Inventors: Vladimir Yliy Gershtein, Alexander Schwarz, Wayne Thomas McDermott, John Frederick Cirucci, John Christopher Ivankovits

Patent number: 6901941Abstract: 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.Type: GrantFiled: July 10, 2002Date of Patent: June 7, 2005Assignee: Air Products and Chemicals, Inc.Inventors: Vladimir Yliy Gershtein, Pingping Ma, Steven W.

Publication number: 20040154333Abstract: This invention relates to a process and apparatus for delivering an ultra high purity fluid comprising at least one component to a point of use at a required pressure without pumping. In one embodiment, a high purity feed comprising at least one component in gaseous or liquid form is charged into a vessel and at least partially solidified, i.e., converted to a solid phase source. As the feed is converted to a solid phase source, additional feed may be added until the vessel is at least substantially filled with a solid phase source or slush. Once filled, the solid phase source or slush may be isochorically heated whereby the solid phase source is converted to a product at an elevated pressure. In other embodiments, an apparatus and a method for the production and collection of a high purity solid phase source or slush comprising at least component is disclosed herein.Type: ApplicationFiled: January 9, 2004Publication date: August 12, 2004Inventors: Vladimir Yliy Gershtein, Alexander Schwarz, Wayne Thomas McDermott, John Frederick Cirucci, John Christopher Ivankovits

Patent number: 6457327Abstract: The process removes from a diluted gas one or more fluorine compounds present at a first concentration in the diluted gas and concentrates the fluorine compounds. This is done by directly contacting the diluted gas with a cryogenic liquid having a temperature less than or equal to about −150° F., thereby producing a vapor lean in the fluorine compounds and liquid enriched with the fluorine compounds at a second concentration. The second concentration is greater than the first concentration.Type: GrantFiled: May 8, 2000Date of Patent: October 1, 2002Assignee: Air Products and Chemicals, Inc.Inventors: Zbigniew Tadeusz Fidkowski, John Frederick Cirucci, Rakesh Agrawal, Timothy Edward Conway
