✦ Synopsis

On the basis of Kolmogoroff's theory of local turbulent isotropy, an attempt is made to describe quantitatively the mass transfer process in liquid-liquid dispersion systems. On condition that the mass transfer resistance is located in the continuous phase, equations are developed for the two extreme cases: (a) when the liquid drops behave like rigid spheres and (b) when its surface is perfectly mobile. The assumption made, that the break-up-coalescence process does not affect the transfer mechanism is confirmed by the results of the extraction experiments in high turbulent pipe flow. It is noticed that the mechanism considered can be also extended to other similar cases of liquid-liquid mass transfer processes when turbulent isotropic flow field is realized.

Mass transfer rates were measured for smooth pipe sections of benzoic acid dissolving in glycerine-water solutions. For Reynolds numbers of 10,000 to 100,000 and Schmidt numbers of 430 to 100,000, the data were correlated with an average deviation of 5.4 per cent by the equation Nsh = 0.0096 NR~ O.9
