Experimental modeling of slip velocity in an L-shape pulsed packed extraction column using response surface methodology

Abstract

The “L-shaped pulsed packed extraction column,” a distinctive form of extraction column, is used in this study to examine the impacts of operational parameters and the physical features of the liquid systems on the slip velocity in a pilot plant. This assessment is done using response surface methodology (RSM). The operational factors of pulsation intensity, dispersed phase flow rate, and continuous phase flow rate are examined through the use of central composite design (CCD) on slip velocity. In the absence and presence of a mass transfer agent (acetone), two common liquid-liquid systems—butyl acetate and water and toluene and water—were used as the chemical systems. Interfacial tension, dispersion phase flow rate, and pulsation intensity are among the parameters that have been found to have a substantial impact on slip velocity. However, the slip velocity was either unaffected or was very slightly affected by the continuous phase flow rate and the mass transfer agent's presence. In addition, new practical models with R2 > 0.93 are presented to predict slip velocity by RSM. Finally, new comprehensive correlation based on dimensional analysis procedure, is put out to precisely forecast the slip velocity. For all of the investigated operating parameters and chemical systems, there was good agreement between predictions and experiments.
