Definitions

  • the present invention relates to a process for destroying organic products with toxic effects avoiding pollution of the surrounding environment after an incident, accident or any other case requiring the decommissioning of these products.
  • the invention also relates to installations implementing this method.
  • PCBs polychlorinated biphenyls
  • the present invention proposes to avoid these drawbacks and it provides a process for destroying toxic organic molecules without having the risk of the dangers mentioned above, in particular of the formation of very toxic degradation products, while minimizing the volume of gas released, this process being characterized by the fact that it comprises as main stage a steam cracking operation.
  • this steam cracking is carried out in a reducing medium in the presence of hydrogen.
  • the quantity of hydrogen chosen as the reducing medium is between 1 and 1.5 Nm 3 / kg of product to be treated.
  • the presence of such a reducing medium has the effect of preventing the oxidation of organic products leading to very toxic by-products of the dioxin type in the case of the destruction of a compound of the PCB family.
  • reaction temperature is between 1000 and 1500 ° C.
  • the process is carried out by injecting superheated steam and oxyhydrogen combustion.
  • the quantity of hydrogen necessary for this oxyhydric combustion corresponds to an excess of 2 to 10% compared to the stoichiometric conditions.
  • the invention covers any installation comprising a combustion and mixing chamber with admission of hydrogen, oxygen and water vapor; at least one reactor receiving the mixture resulting from such combustion and the product to be treated and, at the outlet of this reactor, stations for condensing and treating the solid, liquid and gaseous reaction products.
  • the installation shown in the figure consists of a known diffusion burner 1, a combustion and mixing chamber 2, a reactor 3, a condenser 4, a tank 5 for storing products condensates and an evacuation 17 of the gases to a conventional treatment device not shown.
  • the diffusion burner 1 comprises a pipe 6 for injecting hydrogen or nitrogen, a pipe 7 for injecting oxygen or air. These two pipes supply a plurality of diffusers.
  • the diffusion burner 1 also includes a pipe 8 for propane and oxygen injection supplying the ignition pilot flame and a water supply circuit 9 for cooling the burner jacket.
  • the combustion and mixing chamber 2, placed above the burner 1 and comprising a supply of water vapor 10 modulates the temperature and the residence time.
  • the product 11 to be treated is injected, for example pyralene and water vapor 12 serving as carrier gas and steam trap.
  • Product 11 is admitted into an ultrasonic resonance injector requiring an ap point for example water vapor 12, which improves the spraying and thereby the efficiency of the reaction.
  • the chamber 2 and the reactor 3 have nozzles 13 and 13a for thermocouples and operating control manometers.
  • the condenser 4 has in its upper part an inlet for water 15 ensuring the condensation of the water for cooling the gases and an inlet for a basic product 16 for example diluted sodium hydroxide allowing the neutralization of the hydrochloric gas formed in the case treatment of chlorinated products.
  • the decomposition by-products include in particular naphthalene, diphenyl, phenanthrene, fluoranthene, heavy hydrocarbons.
  • the gases released consist of excess hydrogen and light hydrocarbons: C2 / C3 fraction; these gases are burnt in a flare but can advantageously on large units be used as a heat source for the production of water vapor necessary for the process.
  • the sources of hydrogen suitable for carrying out the process can be any, that is to say that the hydrogen can be supplied by an industrial gas (coke oven gas, flue gas ...) or by domestic gas.
