Abstract
Solvent containing a product (or precursor for the product) and anti-solvent are introduced via tangential inputs respectively of a fluidic vortex mixer The emerging mix from axial outlet is supplied directly to a precipitate entrapment device such as filter bed so that precipitate is removed from the solution before the precipitated particles have time to grow. Filtrate is treated in a reduced pressure evaporator to recover anti-solvent and return concentrated solution for combining with a product make up stream at and return to tangential input of the fluidic vortex mixer.
