The thermodynamic study of liquid-liquid equilibrium (LLE) can provide insights for understanding the process of furfural extraction of water by extraction in biorefinery plants, which produces high value-added products. The present work aimed to use the LLE of the water (1) + fufural (2) + solvent (3) system from experimental data and computer modeling for simulation or liquid-liquid extraction behavior using different solvents, verifying its efficiencies. The solvents studied were p-xylene, toluene, benzyl alcohol, acetophenone and methyl isobutyl. The thermodynamic NRTL model was able to monitor well the studied system. With a simulation run on Aspen Plus®, verify that the system adopted is an economically viable process.
