Comparison of Pilot Data with Predictions from the U.S. EPA (Environmental Protection Agency) SPRAYMOD Computer Program

摘要

The report compares SO2 removal predictions of the EPA-developed SPRAYMOD computer program with 12 different data sets collected at the University of Tennessee with a 1000 cfm (28.3 cu m/min) lime spray dryer operating without recycling of the baghouse collected solids. The experimental results were obtained with spray dryer operating conditions of: SO2 concentration, 633-3178 ppm; inlet gas temperature, 123-171 C (254-339 F); and approach to saturation, 8-20 C (14-36 F). The predicted SO2 removal efficiency depended on SO2 concentration and/or slurry concentration as well as the user's choice of the model reaction rate coefficient (KR).
