Abstract An innovative technique to remove SO 2 from flue gas, comprising a rotating packed bed (RPB) coupled with an electric‐field device, is presented herein. The effects of operating conditions, such as packing type, rotation speed, gas‐liquid volumetric ratio, Na 2 SO 3 content, and voltage supply on SO 2 removal efficiency ( η ), as well as the gas‐phase overall volumetric mass‐transfer coefficient ( K G a ), were systematically investigated. Results indicate that a high η can be achieved under certain operating conditions. A correlation to predict K G a was also established and results show that the predicted values are in agreement with the experimental results. This work generally provides a feasible means of intensification for flue gas desulfurization.
