Development of a Continuous Segmented Flow Tubular Reactor and the “Scale-out” concept – In Search of Perfect Powders

The synthesis of powders with controlled shape and narrow particle size distributions is still a major challenge for many industries. A continuous Segmented Flow Tubular Reactor (SFTR) has been developed to overcome homogeneity and scale-up problems encountered when using batch reactors. Supersaturation is created by mixing the co-reactants in a micromixer inducing precipitation; the suspension is then segmented into identical micro-volumes by a non-miscible fluid and sent through a tube. These micro-volumes are more homogeneous when compared to large batch reactors leading to narrower size distributions, better particle morphology, polymorph selectivity and stoichiometry.
