Field of Research: Continuous crystallization
Crystallization is a key unit operation for separation and purification in the fine chemical and pharmaceutical industry. A tight control of product quality characteristics like crystal shape and crystal size distribution is crucial as they affect following downstream processes. At present, crystallization is commonly conducted in batch mode, although continuous processes offer several advantages. Therefore, the development of continuous crystallization processes has moved into the focus of research.
In this work, a continuous taylor-couette crystallizer is developed and characterized. It consists of two concentric cylinders, of which the inner one rotates while the outer one is stationary. As a result, toroidal vortices are induced in the annular gap that reduce axial dispersion and enhance mixing also for small volume flow rates. Different geometries and operating parameters are investigated towards an enhanced control of crystal product quality.
