Mass Transfer in a Rotating Packed Bed: A Critical Review

Process intensification in rotating packed bed (RPB) has been demonstrated to be a favorite and spotlight in field of multiphase transportation and reaction. The state of the art in the field of mass transfer has been investigated and proposed. In this review, firstly, highlighted modifications on rotor and distributor are developed and enumerated to inspire the potential on mass transfer. Additionally, various methods are presented and compared based on their adaptation. Then, much effort has been directed at analyses below: Characteristics of flow are qualitative in flow distribution while characteristics of mass transfer are quantitative in correlations and parameters. Finally, applications which are excellent in mass transfer among conventional chemical industry and emerging industry are described. The review mentions the considerable opportunity for exploitation of hybrid technology in mass transfer and highlights the valuable challenge in multidisciplinary integration. To inspire the potential on mass transfer process in RPB, fundamental research on structures, methods, characteristics and applications are also prospective.
