Mathematical Modeling of Differential Equations of Concentration in a Sieve-Plate Extraction Column
In this study, the solute concentration in a Sieve-plate column was modeled. Two different models that were continuous phase axial dispersion model and disperse-continuous phase axial dispersion model were considered to simulate the behavior of the plate column under different flow rates. In fact, the solute concentration profiles in both disperse and continuous phase based on dispersion model with and without consideration of axial dispersion in both phase were studied. These models were validated by mass transfer tests with n-butanol/ acetic acid/ water system. According to results, the average deviation of 4.84% and 4.76% between experimental data and simulation outcomes in steady state condition were obtained for the models respectively, which showed a good agreement. Moreover, when…
