Abstract: Accurately determining thermodynamic properties is essential for process simulation and optimization in bioprocess engineering. Among these properties, activity coefficients are crucial for describing the non-ideal behavior of liquid mixtures. In this work, we developed a computational code to estimate the parameters required to calculate the activity coefficients of furan, furfural, and oxolane, using the Wilson, Van Laar, and NRTL thermodynamic models. Parameter estimation was performed by fitting experimental vapor-liquid equilibrium data. A comparative analysis between the models and the experimental data was conducted using T-x-y diagrams, allowing us to evaluate the performance of each approach. The results indicated good agreement between the simulated and experimental data, with occasional divergences in the vapor-phase region, attributed to the consideration of ideality in this phase in the present study. The results demonstrate the feasibility of the proposed model and highlight the potential for improving the computational code for future applications in separation process simulations.
