Micromixing of a Two Phase System in a Stirred Tank with Multiple Impellers
The competitive iodide/iodate reaction scheme was used to ascertain the micromixing in the stirred solid-liquid systems.Two different glass beads from 450 to 1250μm were tested.The effect of solid particles on reaction selectivity with multiple impellers at different feed points has been investigated.It was confirmed that glass beads as a second phase were suitable for the study.The segregation index has changed significantly only for the medium-sized particles at relatively high solid holdups.The cloud formation was clearly observed for the medium-sized particles at a concentration of 12.12 wt.%.When feeding into the clear liquid above the cloud,the value of the segregation index increased significantly.However,in the presence of particles of 1-1.25 mm,the influence on the selectivity was negligible when the agitation speed was increased.
