Abstract
A method for wet oxidation of organic material, characterized by the utilization of the heat generated by the oxidation of the pollutants that are present in a first preheated wastewater introduced at the base of the reactor in order to provide the energy sufficient to trigger the oxidation reaction in a second wastewater, which is introduced in a higher point with respect to the base of the reactor and has a temperature that is proximate to the ambient temperature and a high concentration of pollutants; and an apparatus adapted to provide this innovative wet oxidation method.
Claims8
A method for the wet oxidation of one or more oxidizable compounds, comprising the steps of introducing into a wet oxidation apparatus oxygen, introducing in the wet oxidation apparatus a first wastewater having a first COD and a first input temperature between 200° C. and 280° C., and subjecting the first wastewater to wet oxidation to obtain a reaction mixture at a reaction temperature, and introducing in the wet oxidation apparatus in the reaction mixture a second wastewater having a second COD and a second input temperature equal to 25° C. and subjecting the second wastewater to wet oxidation, the reaction temperature and the second input temperature being such as to allow continuation of wet oxidation of the first wastewater and wet oxidation of the second wastewater, the CODs being reduced by the wet oxidation of the wastewaters.
