Abstract

Stagewise forward mixing model considering coalescence and redispersion of drops ‎was used to predict the performance of Rotating Disc LIQUID-LIQUID EXTRACTION ‎Contactors. Experimental data previously obtained in two RDC columns of 7.62cm ‎diameter, 73.6cm height and 21.9cm diameter, 150cm height were used to evaluate ‎the model predictions. Drop-side mass transfer coefficients were predicted applying ‎Handlos-Baron drop model and Olney"s model was used to predict drop velocities. ‎According to the results obtained the followings could be concluded: (1) If the height ‎of coalescence and redispersion i.e.: h=h__p#f__p/#F could be estimated, the ‎Stagewise forward mixing with coalescence and redispersion model will predict the ‎column height and efficiency with the acceptable accuracy, (2) The Stagewise ‎modeling predictions are highly dependent on the number of stages used when the ‎number of stages is less than 10 and (3) Application of continuous phase mass transfer ‎and axial dispersion coefficients (Kc and Ec) obtained from te solute concentration ‎profile along the column height will predict the column performance more accurately ‎than the Calderbank and Moo-Young (for Kc) and Kumar-Hartland (for Ec) ‎correlations‏.‏
