New advance in application research of high gravity process intensification technology

Process intensification (PI) has generated considerable interest as a potential avenue for sustainable and green development within the chemical industry. High gravity (HiGee) technology is regarded as a significant breakthrough in PI, as it has possessed the potential to increase the mass transfer rate by similar to 1-3 orders of magnitude in comparison to conventional equipment. Rotating packed bed (RPB), as a classical HiGee apparatus, has been proven to have great advantages for application in various chemical engineering fields, for it can provide large contact area between phases, faster surface renewal rate and more homogeneous nucleation sites, and so on. As research on HiGee technology has become more advanced, it is necessary to collate the various studies on the application of HiGee technology in different fields systematically. This work mainly reviews the research progresses of HiGee technology in synthesis of chemicals, preparation of particles, and separation in recent 5 years. Specifically, the latest applications of HiGee technology under different demands and novel structures of RPB designed for various working conditions are presented. Finally, the opportunities and further research directions of the HiGee technology are proposed.
