Process Intensification in Rotating Packed Beds (HIGEE): An Appraisal

Rotating packed beds have received considerable attention as a means of process intensification for gas−liquid mass transfer over the past 2 decades. In this work, we take a critical view of the developments in understanding the transport processes in rotating packed beds. The intensification achieved so far falls short of the goal of 2−3 orders of magnitude volume reduction compared to that obtained conventional columns. The directions toward achieving this goal are outlined.
