✦ Synopsis

A new turbulent oscillating drop model for predicting drop-side solute mass transfer in agitated liquid-liquid systems is proposed. The model assumes that drop deformation and oscillation due to the surrounding agitated fiow field results in random radial mixing within the drop. An effective diffusivity dependent on power input, drop size and interracial tension is derived as follows: D:=D,,+ KllpDd1%2;~ 96Ou The above coefficient is substituted for the molecular diffusion coefficient in the spherical drop diffusion equation which is solved in the normal manner to predict drop-side mass transfer rates. The proportionality constant, K, must be determined from extraction column mass transfer data, e.g. by comparing experimental and column model predicted longitudinal solute concentration profiles.

## Emulsion drop size distributions have been measured at various locations in a turbine mixer for the methyl isobutyl ketone-salt water system. The drop sizes are strongly dependent on the sampling position, being smallest near the impeller tip and largest at the bottom of the mixing tank. The va
