MODELING OF FLUE-GAS DESULFURIZATION USING DRY ADDITIVES

The objective of this work is to investigate the behavior of the two m ain mathematical models used for the estimation of SO2 reduction with the application of the dry additive method. The shrinking-core and por e-tree models for the conversion of the reactant CaO to CaSO4 are test ed for various parameters such as SO2 concentration, temperature of th e flue gas, porosity and diameter of the sorbent particles. Furthermor e, a comparison between the accuracy of predictions of these two model s, using experimental test cases, is presented in this paper.
