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 volumeβrelated liquidβside mass transfer coefficients in mechanically agitated gasβliquid contactors. Significant disagreement can be observed concerning the proposed correlations, so that no single corre
