The conversion of two-phase esterification was performed with the employment of two approaches whereby in the first approach, pseudo-homogeneous phase was assumed and deviation from the experimental data was noticeably observed; and to overcome the drawback, in the second approach, vapor-liquid equilibrium (VLE) was accounted for using ASPEN PLUS and the reaction was allowed to occur in small-time steps using the fatty acid catalyzed kinetics model prior to subsequent VLE calculation. It is assumed in the second approach that transfer between the phases would be faster than the reaction in the separate phases. The outcomes of the second approach show good agreement between the calculated conversion and experimental esterification data in the presence of two phases.
