A model of the reaction between SO 2 and calcium‐based slurries is presented. The model is coupled with an extensive model of the evaporation process and considers external SO 2 mass transfer and liquid‐phase mass transfer of dissolved sulfur and calcium species in both the film surrounding the calcium particles and the bulk liquid phase. The model assumes that particles do not circulate within slurry droplets and that evaporation results in an accumulation of particles at the droplet surface that causes a shift in the controlling mechanisms. Agreement between the model and data available in the literature is excellent.
