20080234530 | Atmospheric Pressure Plasma Treatment of Gaseous Effluents - The invention relates to a method for the conversion of a gas or gas mixture and, in particular, a fluorinated gaseous effluent. According to the invention, at least one bond between two atoms of at least one molecule of the gas or gas mixture is broken under the influence of an electric and/or magnetic field to which the gas or gas mixture is subjected. The gas or gas mixture stream is injected through the electric and/or magnetic field in a non-rectilinear manner in order to increase the distance travelled by the gas molecules through the field and, in this way, increase the effectiveness of the conversion of the gas or gas mixture molecules. | 09-25-2008 |

20090304950 | Method for Cold Plasma Treatment of Plastic Bottles and Device for Implementing Same - The present invention relates to a method for treating plastic bottles comprising an operation for cold plasma sterilization with non-germicidal gasses and/or an operation for the cold plasma deposition of a diffusion barrier layer, said method being characterized in that said cold plasma delivers adjustable nonthermal energy to the entire inside surface of the bottle, said cold plasma being generated either through a distributed propagation of microwaves having a maximum intensity in the vicinity of said surface or by a hollow cathode system adapted to the bottle and supplied with pulsed DC and/or RF voltage. The invention also relates to the devices for implementing the method. | 12-10-2009 |
20090314626 | METHOD FOR TREATING EFFLUENTS CONTAINING FLUOROCOMPOUNDS LIKE PFC AND HFC - The invention relates to a method for destroying effluents issuing from a reactor, the said effluents being transported through at least one pump towards plasma means capable of destroying at least certain bonds in the molecules of the PFC or HFC type between the fluorine and the other elements of these molecules of the PFC or HFC type, in order to generate first species which are then converted to second gaseous, liquid or solid species before interaction of these second species with dry or wet purifying means. According to the invention, at least one reducing agent is injected upstream and/or downstream of the plasma, but upstream of the purifying means, in order to react with the first species created. | 12-24-2009 |
