摘要： The present invention relates to a method for continuously preparing mineral particles by means of the thermolysis of mineral precursors in an aqueous medium, comprising contacting: a reactive flow, including mineral precursors at a temperature lower than the conversion temperature thereof; and a heat transfer flow that is countercurrent to said reactive flow and contains water at a temperature that is sufficient to bring the precursors to a temperature higher than the conversion temperature thereof, the mixture flow that results from said reactive flow and said heat transfer flow then being conveyed into a tubular reactor, inside of which particles are formed by gradually converting the precursors, and where the reactive flow and the heat transfer flow are placed in contact with each other inside a mixing chamber, inside of which the reactive flow and the heat transfer flow are fed by supply pipes having outlet cross-sections that are smaller than the maximum cross-section of said mixing chamber. The invention also relates to a device for implementing said method.

摘要： The invention relates to a method for decontamination of a liquid effluent including one or more radioactive chemical elements to be eliminated including the following steps: a step of bringing into contact in a stirred fluidised bed, in a first zone of a reactor, of the said liquid effluent with solid particles able, by coprecipitation and/or adsorption and/or ion exchange, to capture and retain the said radioactive chemical element or elements, as a result of which a suspension of solid particles is obtained containing the said radioactive chemical element or elements; a step of settling, of the said suspension, in a second zone of the same reactor, where this second zone is separate from the first abovementioned zone, as a result of which a solid phase is obtained including the solid particles containing the said radioactive chemical element or elements to be eliminated, and a liquid phase with a reduced or zero content of the said radioactive chemical element or elements to be eliminated; and a step of separation of the said solid phase and of the said liquid phase.

摘要： A method for decontamination of a liquid effluent including one or more radioactive chemical elements to be eliminated is disclosed. According to one aspect, the method includes The method includes mixing, in a first zone of a reactor, solid particles with the liquid which are able, by co-precipitation, adsorption and/or ion exchange, to capture and retain the radioactive chemical elements. The solid particles settle in a second zone of the reactor. The solids, including the radioactive chemical elements, are then separated from the remaining liquid.
