ABSTRACT:
The present invention provides a process to create without mechanical agitation a zone of low shear, low turbulence flow pattern within a continuous liquid phase contained in a vessel and comprising a dispersed phase consisting of particles or immiscible liquid droplets which have a density different from and should be distributed within the continuous phase without excessive agglomeration or breakups in order to largely preserve the initial particle size distribution, by a continuous or periodic re-circulation of at least a part of the continuous phase which is preferably free of dispersed particles or droplets.
