Abstract

Abstract: High gravity(Higee) technology is one of the novel technologies for process intensification and it is usually carried out in a rotating packed bed(RPB),which can tremendously intensify mass transfer and micromixing processes. After decades of predecessors' efforts,the fundamental research and industrial applications of RPBs have been made great progress. In this paper,the various types of packing used in the RPB,the visualization of fluid flow,and mass transfer and micromixing performance with different packings were summarized. The advantages and disadvantages of different packings were analyzed for various applications. The merits and limitations of different visualization techniques were also pointed out. Some suggestions were proposed to further enhancement of mass transfer and micromixing processes. Industrial applications of RPBs in recent years,including advanced chemicals,marine natural gas purification,preparation of nanomaterials,and environmental protection,were summarized and the potential industrial applications of RPBs were also forecasted.
