Patent number: 6913029Abstract: A process and apparatus to deliver both process chemical and solvent for cleaning the process chemical in a solvent purge refill system along with an integral solvent sorption module, in a single “assembly” that permits ease of shipping, minimal end-user interaction, sufficient solvent for the solvent purge operation, without residual solvent, requiring disposal. This eliminates customer handling of the solvent, and eliminates the customer's need to find a solvent waste facility, as residual solvent can be returned in the same package in one piece/one step.Type: GrantFiled: September 15, 2004Date of Patent: July 5, 2005Assignee: Air Products and Chemicals, Inc.Inventors: Robert Sam Zorich, David Allen Roberts, George Oleg Voloshin

Patent number: 6534666Abstract: This invention relates to an improvement in a purification process for producing those liquid copper based complexes of &bgr;-diketones and, particularly the monovalent copper complexes of &bgr;-diketones, which are suited for application by chemical vapor deposition in the electronics industry. In the basic process for preparing a copper based complex, a reactive copper compound is reacted with a fluorinated &bgr;-diketonate and an organo source such as an olefinic source or one having acetylenic unsaturation. Purification is effected by contacting reaction product with a double deionized deoxygenated water source and preferably an acid/water source. An aqueous layer and an organic layer are formed with the aqueous layer containing byproducts and the organic phase containing product.Type: GrantFiled: December 27, 2001Date of Patent: March 18, 2003Assignee: Air Products and Chemicals, Inc.Inventors: Robert Sam Zorich, James Richard Thurmond, David Allen Roberts

Patent number: 6341615Abstract: A vacuum purge system is provided to protect the vacuum pump from becoming flooded with liquid that on occasion is purged with vapors from process equipment. The liquid is trapped in a vessel and then evaporated and exhausted through the vacuum pump as vapor. Evaporation of trapped liquid is effected by reducing or stopping the purge stream to the trapping vessel while continuing to operate the vacuum pump, thereby reducing the absolute pressure within the vessel. Evaporation of liquid can also be effected by supplying heat to the trapped vessel, either in cooperation with or instead of the pressure reduction. Use of a programmable logic controller enables a cyclic operation that traps liquid from entering the pump, removes the trapped liquid as vapor, and then resumes normal purge operation.Type: GrantFiled: September 13, 2000Date of Patent: January 29, 2002Assignee: Air Products and Chemicals, Inc.Inventors: Robert Sam Zorich, David James Silva
