The pulsed disc-doughnut column is used in various industrial applications. Knowing size distributions of the dispersed phase droplets through this column is necessary to management decisions for better extraction efficiency. To address this, we used various operational parameters, traditional sampling, characterizations, and maximum entropy modeling, and population balance equations to propose species distribution models for the size of droplets in the extraction zone. This paper is devoted studying the size distribution of the dispersed phase using three various liquid feeds in the absence of mass transfer at three operating variables, including the pulse intensity (Af) and flow rates of both liquid phases. The new correlations are proposed to describe Lagrange multipliers of the maximum entropy model regarding operating factors and the physical properties of phases. The population balance model was used to describe the distribution of droplets with main parameters in the breakage and coalescence functions. The comparison appears excellent agreement between these models and the experimental data. The maximum entropy principle has been a straightforward strategy that has successfully described droplet sizes.(c) 2022 Institution of Chemical Engineers. Published by Elsevier Ltd.
