Gas-liquid mass transfer processes are widely used in chemical industry. Studies of gas-liquid mass transfer enhancement have vital significance in many aspects

including shortened process

reduced equipment size

lower investment

lower operating cost

etc. High gravity (also called Higee) technology with a core device of rotating packed bed (RPB) is one of the effective technologies for mass transfer enhancement. Based on research and development in 30 years

significant progress has been made in high gravity process intensification technology in fundamental and application researches

especially in these processes limited by mixing or mass transfer rate. According to rotor structure

such as block packing rotary rotor

two rotating disks rotor

rotating and static disk combined rotor

research progress and theoretical achievements about mass transfer intensification in RPBs are reviewed. The topics of future development of gas-liquid mass transfer enhancement are also suggested.
