Abstract

A multistage agitated column was investigated for use as a countercurrent gas-slurry contractor. Experimental results show that at high gas rates and low impeller speeds the impellers became flooded with air and the rising gas approached slug flow as in highly aerated bubble columns. The overall effect of the solids concentration on the gas holdup was to decrease the holdup with increasing concentration. The effect is two fold. Increasing the gas rate effectively increased the slurry rate through the column and reduced the solid holdup.
