Abstract: The problem of gas absorption with reaction, in a slurry containing fine particles, is important in the development of processes for the removal of acidic pollutants such as sulfur dioxide. Typically, lime and lime stone slurries can be used for removal of sulfur dioxide. However, magnesium hydroxide slurries may yield a higher scrubbing capacity as a result of the more soluble reaction product, magnesium sulfite, compared to the corresponding calcium salt. In this study, absorption experiments were carried out in a stirred cell and the resulting data is analyzed using the model proposed by Mehra [Chem. Eng. Sci. 1996, 51, 461-477]. The proposed theory incorporates the process of particle dissolution and the consequent change in particle size near the gas-liquid interface, using Higbie's model of mass transfer with chemical reaction. A population balance approach is used to track the particle size distribution.
