Higee Contactors: Features and Configurations

This lecture covers the features, drawbacks, and various configurations of Higee contactors, focusing on the high mass transfer rates, selectivity, and new applications enabled by these devices. It also discusses the drawbacks such as rotating equipment, energy requirements, and mechanical stability issues. Different configurations like single block, split-packing, and rotating zigzag bed are explained in detail, highlighting their advantages over conventional packed beds. The lecture delves into the principles, features, and efficiency of rotating packed bed (RPB) contactors, emphasizing their high mass transfer rates, low mixing times, and suitability for fast catalytic reactions. It also explores the characterization of Higee contactors through typical measurements and segregation/mixing time analysis.
