“…N Js (7) However, higher value of the exponent of NIN js obtained in our work suggest that increase of impeller speed is more effectively utilized to cause solid-liquid mass transfer in multiple impeller agitated reactor.

The mass transfer coefficientsbetweensolid particlesand liquidsin high aspect ratio contactors agitated by multiple impellers have been reported. Two vessel sizes i.e.,0.15 m and a.30m l.D. each with a length of 1.0m were used. The effects of particle size, liquid viscosity and agitation speed were studied using two types of impellers, i.e., disc turbine (DT) and pitched turbine downflow (PTD). The spacings between two impellers were maintained at tankdiameter. Asimplemasstransfer correlation basedoncritical suspension speed is proposed.

“…Note that the reduction in the present data is even more severe than that found by Hansford and Litt. 4 It should be reiterated that the ion in the present study is a much stronger electrolyte than the benzoic acid used by Hansford and Litt. 4 Another interesting feature of Figure 5 is the apparent plateau or slow decrease in D/Do values that ranges from about 0.75% to 2.5% concentration.…”

synopsisDiffusion in polyelectrolyte solutions was studied. The mass transfer was determined by an electrochemical technique which involved transport from the fluid to the tube wall. It was found that diffusion behavior depended on the ionic nature of the diffusing species. Neutral molecules showed an increase in diffusion coefficients. This was apparently due to both solvation of solvent molecules and extension of polymer molecules. Ionic diffusing species showed a decrease in diffusion coefficients. The greater the ionic strength, the greater the decrease. The effect was most likely due to ionic interaction with the polyelectrolyte molecules.
