Flue gas desulphurization by spray dry absorption

Absorption efficiency of sulphur dioxide in spray dry absorption depends on the superposition of the absorption process with the drying process. A mod el has been established considering heat and mass transfer processes for a single droplet and the two phase flow inside the spray dryer. Model predict ions are compared with experimental data showing the influence of drying co nditions and stoichiometric ratio on the absorption efficiency. (C) 2000 El sevier Science S.A.
