The use of dry injection of sorbents for control of S02in conjunction with a fabric filter is currently undergoing evaluation at the large pilot plant level, and is being considered for full scale application. This paper discusses a recently developed model for predicting the removal efficiencies of S02as a function of system operating parameters, and utilizing a semi-emperical pore plugging experience to account for the observed reaction die off behavior. The model assumes that the reaction between the gas and the solid occurs in two phases; (1) in a transport-line section where the finely powdered solid is injected and mixed with the flue gases, and (2) across the filter cake which develops at the fabric filter. In the current development of the model, isothermal conditions are assumed. Comparisons between predicted and reported values of S02removal are given for the Na2C03—S02system.
