摘要

Abstract

In this study

the mean droplet diameter in the cavity zone and the total mass transfer area of a multi-stage highspeed disperser (HSD) reactor with different packing combinations were measured and evaluated. The effects of rotational speed and packing radius

as well as the packing ring radius and numbers

on the mean droplet diameter and the total mass transfer area were evaluated. A model was established to calculate the mass transfer area in the cavity zone in the HSD reactor

and it was found that the packings contribute 61%-82% of the total mass transfer area. A correlation for predicting the mass transfer area in the packing zone was regressed by the dimensionless analysis method. An enhancement factor based on the mass transfer area in the packing zone was proposed to evaluate the effect of packing combination on mass transfer area. Two optimum packing combinations were proposed in consideration of the mean droplet diameter and the enhancement factor.
