In Part I of the article there were reported profound differences in behaviour between the bottom and the upper stages of a multiple-impeller vessel under gassed conditions: the volumetric mass transfer coefficient, kLa, for the bottom stage was by up to 50% lower than that for the upper stages.

method is described for evaluating the gas-liquid mass transfer coefficient k,a in agitated vessels from transient-response measurements. It involves cbncentration measurements at several places in the liquid phase and an axial dispersion model for the gas phase. Results are presented showing the di
## Abstract There are a large number of correlations given in literature for the prediction of volume‐related liquid‐side mass transfer coefficients in mechanically agitated gas‐liquid contactors. Significant disagreement can be observed concerning the proposed correlations, so that no single corre
Volumetric mass transfer coefficient, holdup and power consumption were measured in individual stages of the vessel stirred with 4 Rushton turbines on a common shaft. Water and a 0.5 M aqueous solution of Na2SO4 were used to simulate coalescing and noncoalescing batches. Volumetric mass transfer coe
