“…The bulk concentration on each tray is assumed constant, that is, the concentrations of components in both phases do not change within the static and dynamic holdup. Sanpui and Khanna (2002) have suggested that the parallel-parallel mass-transfer resistance model matches well with the experimental results. A summary of the parallel masstransfer-resistance model is given below.…”

“…It has been observed that Skelland and Conger (1973) (for k ij of stagnant drops), Wesselingh and Krishna (1990) (for D ij ), and Siddiqi and Lucas (1986) (for D ij 0 ) as suggested by Sanpui and Khanna (2002) are the best combination for the TAW and MAW systems.…”

“…Drops were spaced more than 60 mm apart, typically with a range of flow-rate between 20.54-120.23 mL/h. Acetone concentration in the collected samples was measured with a GC (Shimadzu, 14B) with FID detector, calibrated with reference substances of toluene and acetone (Merck) for gas chromatography [12,21,28]. The concentration of acetone in the known samples was within the range of 1.5-44.7 g/L with 14 samples in calibration.…”

“…A list of the published correlations for the mass transfer coefficients for the circulating drops has been provided by Sanpui and Khanna [21]. Lochiel and Calderbank [22] developed a model describing the transfer of solutes, around a spherical drop when the Schmidt number is large, i.e., Sc>>1 (about 930 in this work),…”

A combined model was used for prediction of overall mass transfer coefficient of drops in the liquid-liquid extraction process, prone to the deleterious effect of adsorbed hydroxyl ions onto the interface. The importance is due to the use of different pH waters as aqueous phase. The work is based on single drop experiments with a chemical system of toluene-acetone-water where the pH of the continuous aqueous phase was within the range 5.5-8, appropriate to most industrial waters, and can lead to rigid behavior of circulating drops. The combined model in conjunction with the correlation developed here for the ratio of interfacial velocity to drop terminal velocity that links the film mass transfer coefficients of both sides can be used satisfactorily for design purposes. This model gives a maximum relative deviation of less than ±10% for the mass transfer directions of dispersed to continuous phase and vice versa.
