This work presents the modeling and experimental investigation on absorption of CO2 by Benfield solution in rotating packed bed (RPB). A model was established to illustrate the mechanism of gas-liquid mass transfer with reactions in RPB at higher gravity level. Experiments were carried out at various rotating speeds, liquid flow rates, gas flow rates and temperatures in RPB, with Benfield solution as the absorbent. The validity of this model was demonstrated by the fact that most of the predicted y(0) (mole fraction of CO2 in outlet gas) agreed well with the experimental data with a deviation within 10%. The presented profile of K(G)a (gas-phase volumetric mass transfer coefficient) along the radial direction of the packing could reasonably explain the end effect in RPB. As a result, this model is reliable in describing the removal of CO2 by Benfield Solution in RPB at higher gravity level. (c) 2008 Published by Elsevier B.V.
