摘要: Absorption of SO2 from a SO2/air mixture with sodium citrate buffer solution was investigated using a rotating packed bed(RPB) in laboratory scale.The effects of operating parameters, such as the rotation speed of RPB, liquid-gas ratio, inlet gas flow rate, inlet concentration of SO2 in flue gas, sodium citrate buffer concentration and initial pH of absorption solution, on the SO2 concentration in the absorption solution or removal efficiency of SO2 were examined.Incremental rate of sulfate radical ions in the absorption solution was also examined.Experimental results indicate that the efficiency of this regenerative process will be improved by using RPB under appropriate operating conditions, and the generation of SO42- will be restrained in the process in RPB.
