Abstract:
A process for creating without mechanical agitation a flow pattern, in a continuous liquid phase contained in a reaction vessel and comprising a dispersed phase selected from the group consisting of solid particles which can also be coated or immiscible liquid droplets, the dispersed phase having a density different from the continuous phase and undergoing processing during which the particles or droplets need to preserve their size and particle size distribution and to remain submerged and uniformly distributed within the continuous phase, comprising continuously or periodically injecting into selected part(s) of the reaction vessel one or more streams of fluid immiscible and inert to the reaction vessel contents and having a density lower than the reaction vessel contents, so that not less than 90% of the initial particle size distribution of the dispersed phase is preserved, and retrieving this fluid above free surface of liquid phase.
