Abstract Scope SO2 is one of the main sources of acid rain and air pollution. Use of powdered alkaline sorbents is an effective means of removing SO2. This semi-dry process is more economical and efficient than wet or dry desulfurization processes. The reaction between the sorbent (hydrated lime, Ca(OH)2) and SO2 is dominated by the adsorption process. In this study, a mathematical model has been developed to simulate the lab-scale desulfurization reactor employed for the low temperature gases containing low SO2 concentration coming out of the electrolysis cells used for aluminum production. A parametric study was carried out in order to examine the effects of certain parameters, such as inlet SO2 concentration and sorbent flowrate on the desulfurization efficiency. The model and some of the results will be presented in this article.
