Desulfurization mechanism by rotating packed bed was introduced in this paper. In the experiment
pure water
slaked lime and slurry of magnesium hydroxide were used as absorbent for the flue gas desulfurization. The sorts of absorbent
rotating speed
concentration of absorbent and SO-2 concentration in the gas were studied. The results showed that alkaline slurries enhanced the mass transfer rate of SO-2 up to 3
4
times higher than that of pure water. The mass transfer rate of SO-2 in RPB was greatly depended on the flow rate of absorbent and the rotating speed. Under optimal condition
