Process Intensification of Multiphase Processes with a Rotor-Stator Spinning Disc Reactor

An overview of hydrodynamics and mass transfer for cocurrent gas-liquid flow in a rotor-stator spinning disc reactor is presented. The dependency of disc spacing and rotating speed on gas-liquid and liquid-disc mass transfer is discussed. Additionally results for multiple rotor-stator spinning discs mounted on a single axis are presented. Results will be shown for the application of the multiple spinning disc process for the production of a pharmaceutical by an ethynilation reaction. An outlook for further application to liquid-liquid, liquid-solid, and gas-liquid solid processes will be given.
