A series of bench-scale tests was conducted to evaluate a dry, fluidized-bed, scrubbing process for removing acidic gases from incinerator flue gas. The acidic gases studied were sulfur dioxide, hydrogen, chloride, and phosphorous pentoxide. These gases were found to react readily with lime in a bubbling bed operating at 540 to 650/degree/C (1000 to 1200/degree/F). Superficial gas velocity, bed temperature, bed depth, sorbent type, and sorbent conversion strongly affected the degree of acidic gas removal. Sorbent utilization was inhibited by the occlusion of the particle surface by reaction products. 4 refs., 6 figs., 1 tab.
