A device for chemical destruction of at least one feed comprising at least one organic compound are provided. In one aspect, the device comprises at least one inductive plasma torch, means for introducing at least one plasma-forming gas into the torch, optionally when the plasma gas(es) comprise(s) no or little oxygen, means for bringing oxygen gas into the plasma or into the vicinity of the plasma, means for introducing the feed into the torch, a reaction enclosure capable of allowing thermal destruction of the gases flowing from the torch, a device allowing mixing of the gases flowing out of the reaction enclosure to be carried out, means for introducing air and/or oxygen gas into the mixing device, a device allowing recombination by cooling of at least one portion of the gases from the mixing device, the torch, the reaction enclosure, the mixing device and the recombination device being in fluidic communication.

Device for thermal destruction of organic compounds by an induction plasma

An injection and cooling system configured to equip a plasma torch, a plasma torch equipped with the system, an installation for treatment of a liquid solution including such a plasma torch, and a method for treatment of a liquid solution by injection into a plasma generated by such a plasma torch submerged in a different liquid solution.

Arrangement for the outlet nozzle of a submerged plasma torch dedicated to waste treatment

The method according to the invention enables a facility having a rather reduced dimension, for incinerating to be used, melting and vitrifying mixed waste () introduced into a reactor (), by means of a basket () in turn passing through an air lock (). Plasma torches () burn all waste () contained in the basket (). The waste is then lowered in a melting bath of a furnace () with an inductor () including a crucible-forming container (). A combustion gas treatment train completes the facility. The furnace () can be dismantled, after a series of treatments of several baskets () of waste () for disassembling the crucible-forming container () from the furnace (). Application in treating different radiologically contaminated and/or toxic mixed waste.

A method for producing hydrogen via a thermochemical route from water, based on the cerium-chlorine cycle is provided. The method comprises, according to a first reaction scheme, the following reactions:HO+Cl=2HCl+&#xbd;O;&#x2003;&#x2003;(A)8HCl+2CeO=2CeCl+Cl+4HO;&#x2003;&#x2003;(B)2CeCl+4HO=2CeO+6HCl+H;&#x2003;&#x2003;(C)

Method for producing hydrogen via a thermochemical route, based on hydrochlorination of cerium

A device having advantages in terms of equipment maintenance, since it provides maximum limitation of the onset of electric arcing between the electrodes, including a vertical cathode equipped with emissive points, these points being offset at an angle from each other from one plane to another, so as to be optimally distributed in space. One embodiment using two planar anodes, between which several vertical cathodes are arranged equipped with points, is also envisaged.
