Abstract:

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 oxide, hydrogen chloride, and phosphorus pentoxide. These gases were found to react readily with lime in a bubbling bed operating at 540 C 1000 F. Superficial gas velocity, bed temperature, bed depth, sorbent type, and sorbent utilization strongly affected the degree of acidic gas removal. Sorbent utilization was inhibited by reaction product occlusion of the particle surface. Keywords Waste disposal Environmental protection Pollution abatement Air pollution.
