Theoretical analysis of chemisorption of gases in a three-phase system

Kinetics of chemisorption of sulfur dioxide by a limestone suspension is theoretically analyzed and a chemisorption mathematical model, which is used to determine the treatment efficiency of the gas, is developed. It is shown that the gas treatment efficiency considerably increases for the chemical absorption by a suspension containing solid absorbent particles as compared with physical absorption. The gas treatment efficiency rises with increasing solid absorbent mass in the solution and decreasing size of the particles.
