Patent number: 7282099Abstract: Method for processing an article by contacting the article with a dense fluid. The article is introduced into a sealable processing chamber and the processing chamber is sealed. A dense fluid is prepared by introducing a subcritical fluid into a pressurization vessel and isolating the vessel, and then heating the subcritical fluid at essentially constant volume and essentially constant density to yield a dense fluid. At least a portion of the dense fluid is transferred from the pressurization vessel to the processing chamber, wherein the transfer of the dense fluid is driven by the difference between the pressure in the pressurization vessel and the pressure in the processing chamber, thereby pressurizing the processing chamber with transferred dense fluid. The article is contacted with the transferred dense fluid to yield a spent dense fluid and a treated article, and the spent dense fluid is separated from the treated article.Type: GrantFiled: September 24, 2002Date of Patent: October 16, 2007Assignee: Air Products and Chemicals, Inc.Inventors: Wayne Thomas McDermott, Richard Carl Ockovic, Alexander Schwarz

A processing agent may be added to the pressurization vessel, to the processing chamber, or to the dense fluid during transfer from the pressurization vessel to the processing chamber. The ultrasonic energy may be generated continuously at a constant frequency or at variable frequencies. Alternatively, the ultrasonic energy may be generated intermittently.Type: GrantFiled: December 16, 2003Date of Patent: September 11, 2007Assignee: Air Products and Chemicals, Inc.Inventors: Wayne Thomas McDermott, Hoshang Subawalla, Andrew David Johnson, Alexander Schwarz

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
