Abstract

To carry out this investigation, drop behavior in a horizontal pulsed sieve-plated column was measured under with and without reactive extraction situations. Central composite design, a subcategory of response surface methodology, was utilized to survey the influence of the operational parameters on the drop behavior. The effect of the reactive extraction situation was also observed on droplet behavior. According to the experimental results, the effect of pulse intensity on the droplet behavior was greater than the phase flow rates. For the prediction of the Sauter mean drop diameter in a reactive extraction situation, a new correlation was determined. The results obtained via the proposed correlation were closely matched with the experimental results (AARE is about 6.64%). Also, to determine a predictive correlation for drop size distribution, log-normal and normal of probability density function were examined. The constant parameters at these probability density functions are specified by the obtained results as well as the mathematical approach.
