✦ Synopsis

The degradation of foam generated in a semi-batch system, operating under high retention times, has been monitored.

Under the experimental conditions particular to the study, the rate ofdegradation with respect to foam height and the total foam height itself are seen to be sensitive functions of the solubility of the filler gas and of the sparging rate. The first of these is explained in terms of the larger role of interbubble gas diffusion at higher gas solubilities, whereas the second is attributed to the varying residence time of the bubbles with regard to a particular height in the foam bed. Further. the dynamic simulation procedure described in Part I of this work is seen to follow the experimental trends rather well.

The general expressions for the Senftleben effects for a gas of 2LZ molecules are evaluated numerically for the thermal conductivity using a simple model. These effects are strongly dependent on the pressure. Good qualitative agreement is found between theory and the measurements of AX&, for NC+.

David and Wllermaux (1987,1989) and Muhr et al. (1990) have developed and applied a multizone mixing model (MZM) for semi-batch single jet mixing in stirred tanks. The aim of the present paper is to generalize the multizone model (MZM) to the case of a semi-batch stirred tank with two separate feeds
