Argonne has had in operation for the last two years a high-sulfur dry FGC system. (1) We have successfully demonstrated that reliable, economical, removal of sulfur dioxide at, and above, the levels dictated by the NSPS is possible. (2) It has been shown that a lime-based spray dryer can perform successfully in a retrofit mode, removing 70% of the inlet SO/sub 2/. (3) System economics based on actual operation have been ascertained, and seem to be in line with published estimates. (4) Waste studies have indicated that there is a dependence of pH upon leachate concentration but, no concentration of elements were high enough to classify wastes from a dry scrubbing system as hazardous. 7 figures, 4 tables.
