Abstract
A Higee absorption process was developed for removing VOCs (Volatile Organic Compounds) from air into aqueous phase under a centrifugal field. A rotating packed bed, which replaces gravity with centrifugal force, was adopted in this study. Under a centrifugal field, the operating range can be covered in higher gas and liquid flow rates due to the reduced tendency to flood, and mass transfer was also enhanced. The experimental results showed that the mass transfer coefficient was increased with increasing rotor speed, to the power ranging from 0.28 to 0.51. Comparing with the model-predicted values and the experimental data of conventional packed beds, KG a obtained from our experiment was approximately an order of magnitude higher.
