✦ Synopsis

A method for evaluating the mass transfer coefficient, kLa, in a gas sparged stirred vessel from the initial portion of the liquid dynamic response curve is described. The method assumes perfect liquid mixing but is independent of the gas mixing characteristics.

Results obtained from two geometrically similar air-water systems (volume ratio 8 : 1) correlate well over a wide range of operating conditions and are in good agreement with evaluations made on the smaller system using an established and more involved experimental technique.

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.
