The interaction of solute transfer, contaminants and drop break-up in rotating disc contactors: part I. correlation of drop breakage probabilities

摘要

The breakage process of single deops in RDC liquid-liquid extraction columns has been investigated. The breakage probability and daughter drop size distribution were the measured characteristics. Binary systems, non-equilibrated ternary systems with mass transfer in both directions (c→d and d→c) and systems with surface active agent added were used in the experiments. A model of the breakage probability was developed based on a modified Weber number, taking into account the applied shearing stress and the resisting interfacial tension force.
