Patent number: 8105562Abstract: The invention relates to a method and an apparatus for treating exhaust gases comprising organosilicon components or accompanying substances. The invention more specifically relates to the use of bulk regenerator materials as storage materials allowing periodic removal, purification, and redelivery to the system. The invention solves the problem of clogged regenerator-storage materials during regenerative post-combustion of exhaust gases containing organosilicon components.Type: GrantFiled: December 7, 2004Date of Patent: January 31, 2012Assignee: Clausthaler Umwelttechnik-Institut GmbH (CUTEC-Institut)Inventors: Otto Carlowitz, Bernd Ruskamp, Olaf Neese, Frank Kriebisch

Patent number: 8092689Abstract: A method of reducing styrene emissions in aqueous cured-in-place pipe closed molding processes and other aqueous environments using a styrene reduction agent. The reduction agent generally comprises a calibrated mixture of salts including sodium chloride plus three persulfate salts: ammonium (APS), potassium (KPS), and sodium (NPS). These ingredients are combined in powder form and are compressed into soluble capsules containing calibrated amounts of the mixture. The capsule(s) may be prescribed through the use of software. Capsule(s) are added to the cure water prior to starting the boiler equipment for the Cured-In-Place Pipe process in order to reduce the residual monomer content in either process or waste streams.Type: GrantFiled: September 27, 2010Date of Patent: January 10, 2012Inventor: Michel Gosselin

Patent number: 8093442Abstract: The method of the invention provides means of destroying highly stable metal cyanide ions found in a solution, and converting the cyanide to harmless by-products. Contrary to conventional methods which merely complex the cyanide into a mechanically or physically removable complex, the present method destroys the cyanide found in the sample. The invention is directed to a method of destroying cyanide comprising providing a highly alkaline solution containing a metal cyanide ions; and subjecting the solution to electro-oxidation.Type: GrantFiled: July 18, 2008Date of Patent: January 10, 2012Assignee: Rio Tinto Alcan International LimitedInventors: Jacques Labrie, Hugues Menard

Patent number: 8088312Abstract: Method for removing the epoxy and/or phenolic polymer encapsulating a nuclear fuel pellet comprising uranium dioxide UO2, the method comprising the following successive steps: a) the polymer is pyrolysed in a reducing atmosphere; and b) the carbon residues obtained after the pyrolysis step (a) are selectively oxidized, the oxidation being carried out at temperature above 1000° C. in an atmosphere comprising carbon dioxide CO2. Such a method makes it possible to remove the epoxy and/or phenolic polymer encapsulating the pellet while avoiding or limiting the risk of radiological contamination by the formation of U3O8.Type: GrantFiled: July 23, 2009Date of Patent: January 3, 2012Assignee: Commissariat a l'Energie Atomique et aux Energies AlternativesInventors: Eric Hanus, Olivier Fiquet, Nicolas Tarisien
