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.

The effect of diffusivity on gas-side mass transfer coefficient was studied in an experimental bubble column. A fourteen-fold variation of diffusivity was obtained by using a variety of solutes and carrier gases. Both absorption and vaporization experiments were car&d ou< some&es for the same solute
