Mathematical Modeling of Plug flow and Axial Dispersion Models in a Sieve-plate Extraction Column

Mathematical Modeling of Plug flow and Axial Dispersion Models in a Sieve-plate Extraction Column

Modeling of a counter-current Sieve-plate liquid ndash;liquid extractor has been conducted using plug flow (PF) model and axial dispersion (AD) model. Several experiments were done using toluene/ acetic acid/ water system with acetic acid as mass transfer agent from aqueous to organic phase. New analytical solutions are proposed for two models respectively and the simulation results show a good agreement, compared with experimental data. In this paper, the solute concentration profiles in both ...

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 ...
