Process intensification aims for increasing efficiency and sustainability of (bio-)chemical production processes. The second book of our two-book series focusses entirely on process intensifi cation by centrifugally enhanced (reactive) separations. The book provides an overview of the main applications of rotating packed beds (RPBs) in liquid-liquid, gas-liquid and vapor-liquid contacting, within academic research and industrial applications. The book addresses current design rules and modeling frameworks, including the tailored design of functional packings by means of additive manufacturing. Rotating packed beds are widely applicable and fl exible mass transfer machines for process intensifi cation. Applications, design rules and advanced modeling for rotating packed beds are presented in an interconnected way.
