Patent number: 7241340Abstract: The present invention is related to systems and methods for modifying various non-equidimensional substrates with modifying agents. The system comprises a processing chamber configured for passing the non-equidimensional substrate therethrough, wherein the processing chamber is further configured to accept a treatment mixture into the chamber during movement of the non-equidimensional substrate through the processing chamber. The treatment mixture can comprise of the modifying agent in a carrier medium, wherein the carrier medium is selected from the group consisting of a supercritical fluid, a near-critical fluid, a superheated fluid, a superheated liquid, and a liquefied gas. Thus, the modifying agent can be applied to the non-equidimensional substrate upon contact between the treatment mixture and the non-equidimensional substrate.Type: GrantFiled: July 24, 2003Date of Patent: July 10, 2007Assignee: Battelle Energy Alliance, LLCInventors: Stuart K. Janikowski, Mark D. Argyle, Robert V. Fox, W. Alan Propp, William J. Toth, Daniel M. Ginosar, Charles A. Allen, David L. Miller

Patent number: 6984768Abstract: A method for destroying halocarbons. Halocarbon materials are reacted in a dehalogenation process wherein they are combined with a solvent in the presence of a catalyst. A hydrogen-containing solvent is preferred which functions as both a solvating agent and hydrogen donor. To augment the hydrogen donation capacity of the solvent if needed (or when non-hydrogen-containing solvents are used), a supplemental hydrogen donor composition may be employed. In operation, at least one of the temperature and pressure of the solvent is maintained near, at, or above a critical level. For example, the solvent may be in (1) a supercritical state; (2) a state where one of the temperature or pressure thereof is at or above critical; or (3) a state where at least one of the temperature and pressure thereof is near-critical. This system provides numerous benefits including improved reaction rates, efficiency, and versatility.Type: GrantFiled: May 21, 2002Date of Patent: January 10, 2006Assignee: Battelle Energy Alliance, LLCInventors: Daniel M. Ginosar, Robert V. Fox, Stuart K. Janikowski

Patent number: 6962731Abstract: The present invention is related to the modifying of substrates with multiple modifying agents in a single continuous system. At least two processing chambers are configured for modifying the substrate in a continuous feed system. The processing chambers can be substantially isolated from one another by interstitial seals. Additionally, the two processing chambers can be substantially isolated from the surrounding atmosphere by end seals. Optionally, expansion chambers can be used to separate the seals from the processing chambers.Type: GrantFiled: September 23, 2003Date of Patent: November 8, 2005Assignee: Bechtel BWXT Idaho, LLCInventors: W. Alan Propp, Mark D. Argyle, Stuart K. Janikowski, Robert V. Fox, William J. Toth, Daniel M. Ginosar, Charles A. Allen, David L. Miller
