Longitudinal dispersion in rotating impeller types of contactors

Abstract

Abstract On the basis of a back‐flow model, the rates of interstage mixing of continuous phase for RDC and Mixco columns are measured experimentally under flow and nonflow conditions. These rates are correlated into dimensionless formulas for wide combinations of operational condition, column geometry, and dimensions, and are put into a single formula by introducing the power number as an additional parameter. The final correlation covers the impeller Reynolds number from 3.5 × 10 3 to 1.0 × 10 6 and the diameter of columns from 4.1 to 218 cm.
