摘要：

Absorption of SO2 from a gas mixture with an ammonia-based solution was investigated using a counter current rotating packed bed (RPB) with SiC structured packing and plastic packing. Effects of operating parameters, such as the rotational speed, liquid flow rate, gas flow rate, liquid-gas ratio, inlet concentration of SO2, and the alkalinity of absorbent on the removal efficiency of SO2, were examined. Experimental results showed that the plastic packing had a better desulfurization performance under the same operation conditions. Moreover, correlations of gas-side volumetric overall mass transfer coefficients of the RPB with the two types of packing were obtained and the predicted data were in good agreement with experimental results.
