Abstract

In the research work, several series of experiments are carried out by a ten-stage progress horizontal MIXER-SETTLER. In the first series of experiments, the effect of impeller speed on the OVERALL VOLUMETRIC MASS TRANSFER COEFFICIENTs at a constant and specific volumetric flow rates for both phases is studied. In the second series of experiments, the effect of volumetric flow rates of dispersed phase on the OVERALL VOLUMETRIC MASS TRANSFER COEFFICIENTs at a constant impeller speed for all stages is studied. In the third series of experiments, the effect of volumetric flow rates of continuous phase on the OVERALL VOLUMETRIC MASS TRANSFER COEFFICIENTs at a constant impeller speed for all stages is studied. According to the experiments, the following conclusions can be made: -An increase of impeller speed results to an increase of the OVERALL VOLUMETRIC MASS TRANSFER COEFFICIENTs, but after a specific speed (critical speed) the OVERALL VOLUMETRIC MASS TRANSFER COEFFICIENTs decrease. - An increase of raffinate volumetric flow rate results to an increase of the OVERALL VOLUMETRIC MASS TRANSFER COEFFICIENTs. - An increase of extract (solvent) volumetric flow rate results to an increase of the OVERALL VOLUMETRIC MASS TRANSFER COEFFICIENTs. - The obtained results show that the resistance against mass transfer in both phases is considerable high and cannot be neglected none of them.
