INFLUENCE OF INLET DISTRIBUTOR AND COLUMN DIAMETER ON HYDRODYNAMIC CHARACTERISTICS IN RDC LIQUID EXTRACTION COLUMN

Stagewise Modeling of Liquid-Liquid Extraction Column (RDC)

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 appl...

Experimental Investigation of Phase Inversion of Liquid-Liquid Systems in a Spray Extraction Column

An experimental study of the phase inversion behavior of liquid-liquid dispersion has been conducted in a spray extraction column for systems of toluene / water, n-hexane/water, CCl4/water, toluene /water + glycerol (25 % wt), toluene + CCl4 (25 % wt) / water and toluene / acetic acid (5 % wt)/water. The effects of physical properties, mass transfer and column geometry...

Investigation of Packing Effect on Mass Transfer Coefficient in a Single Drop Liquid Extraction Column

Presenting an Empirical Correlation for Maximum Sauter Mean Diameter in a Spray Extraction Column

Based on the importance of drops' behavior in liquid-liquid extraction, the maximum sauter mean drop diameter has been investigated and correlated in a counter-current spray extraction column with two chemical systems. Spargers were set of nozzles in all experiments. Studying the effects of several parameters on drops size, some correlations were estimated by the last available version of softw...
