Abstract
The report presents a comprehensive mathematical model of the SO2 removal process in a spray-dryer flue-gas desulfurization system. Simultaneous evaporation of a sorbent droplet and absorption/reaction of SO2 in the droplet are described by the corresponding heat- and mass-transfer rate relations. Dissolution kinetics of lime particles within a slurry droplet is included in determining the overall SO2 removal rate. The model identifies several important parameters which need to be estimated or determined from experimental data. The report also includes a computer program, 'SPRAYMOD,' written in Basic language, to predict SO2 removal in a spray dryer, based on the model developed. The program is user oriented and easy to use. The contribution of particulate collection equipment, a baghouse and an electrostatic precipitator, toward overall SO2 removal is also discussed.
