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

Patent number: 6469780Abstract: An apparatus and a method are disclosed for detecting particles in a particle-containing gas at a pressure greater than about 0 psig. The apparatus includes a gas distribution line containing a pressurized gas having a pressure greater than about 0 psig and a condensation nucleus counter in fluid communication with the pressurized gas in the gas distribution line. The condensation nucleus counter is adapted to receive a stream of the pressurized gas at a pressure substantially equal to the pressure of the pressurized gas in the gas distribution line. The condensation nucleus counter is constructed of materials resistant to corrosion and to reaction with the pressurized gas, which may be one or more reactive or toxic gases, such as those used in microchip processing, or an inert gas.Type: GrantFiled: December 21, 1998Date of Patent: October 22, 2002Assignee: Air Products and Chemicals, Inc.Inventors: Wayne Thomas McDermott, Richard Carl Ockovic

Patent number: 6383257Abstract: An apparatus and process for separating perfluorocarbon compounds from a gas mixture passes an incoming stream of a gas into a cold trap, the gas stream including a plurality of perfluorocarbon compounds. The gas mixture is cooled within the cold trap to a temperature below −100° C. to produce a condensate that is enriched in at least one perfluorocarbon compound and a non-condensed stream from which the condensate was separated. The condensate is withdrawn from the cold trap. The condensate may be withdrawn by warming the cold trap to vaporize the condensate and thereafter flowing the vaporized condensate into a storage vessel. The non-condensed stream may be vented to the atmosphere, re-circulated into the cold trap or flowed through subsequent separation processes to extract additional perfluorocarbon compounds.Type: GrantFiled: April 4, 2000Date of Patent: May 7, 2002Assignee: Air Products and Chemicals, Inc.Inventors: Wayne Thomas McDermott, Richard Carl Ockovic, Alexander Schwarz, Rakesh Agrawal
