<p>Performing a polyphase chemical reaction, comprises contacting at least a liquid reagent with at least a solid reagent, optionally resulting in the creation of foams and/or insoluble deposits, in a hydrocyclone introducer including a cylindrical upper part and a truncated lower part, introducing tangential liquid reagent into the cylindrical upper part so as to create a vortex in the truncated lower part, and introducing the solid reagent into the hydrocyclone introducer carried out at an internal surface of the vortex to form a reactional mixture. Performing a polyphase chemical reaction, comprises contacting at least a liquid reagent with at least a solid reagent, optionally resulting in the creation of foams and/or insoluble deposits, in a hydrocyclone introducer including a cylindrical upper part and a truncated lower part, introducing tangential liquid reagent into the cylindrical upper part so as to create a vortex in the truncated lower part, and introducing the solid reagent into the hydrocyclone introducer carried out at an internal surface of the vortex to form a reactional mixture, where the truncated lower part has a residential volume for the vortex and the flow of introduction of the liquid reagent and residential volume for the vortex are such that the residence time of the reactional mixture in the truncated lower part is 0.3-2 (preferably = 1) seconds. Independent claims are included for: (1) a hydrocyclone introducer for performing a polyphase chemical reaction comprising an external envelope including a cylindrical upper part and a truncated lower part terminating by outlet tube, and a coaxial central tubular device that is adapted for introducing the solid reagent and comprises an outlet orifice to deliver the solid reagent to the internal surface of the vortex of the liquid reagent, where the external envelope of the cylindrical upper part includes at least a tangential injector for a liquid reagent and the outlet orifice is located inside the truncated lower part of the external envelope of the hydrocyclone introducer so that, for a flow of introduction given of the liquid reagent, the residence time of the reactional mixture of the liquid reagent and solid reagent in the truncated lower part is 0.3-2 seconds, preferably = 1 second; (2) the hydrocyclone pre-reactor for performing a polyphase chemical reaction including an external envelope including a cylindrical upper part and a truncated lower part and at least three tangential injectors for the tangential introduction of part of a reactional mixture from the reactor, where the hydrocyclone pre-reactor is intended to be fluidic connection with a reactor and the cylindrical upper part of the external envelope includes an inlet orifice for a reactional mixture; and (3) a device for performing a polyphase chemical reaction including the hydrocyclone introducer, the hydrocyclone pre-reactor and the reactor.</p> |
