In situ filling and emptying of rotating bed reactors

Video showing how a SpinChem® rotating bed reactor (RBR) was charged with solid particles, followed by draining and replacing the reaction liquid without escape of solids. Lastly, the solid phase was removed without opening the RBR. This procedure illustrates a concept for automatic handling of solid phases in production scale equipment without opening the reaction vessel.
