An innovative technique to remove SO2 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, Na2SO3 content, and voltage supply on SO2 removal efficiency (η), as well as the gas-phase overall volumetric mass-transfer coefficient (KGa), were systematically investigated. Results indicate that a high η can be achieved under certain operating conditions. A correlation to predict KGa 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. |
