“…The performances of FPA and MFPA were quantified and compared based on two metrics: the RMSD values for both thermodynamic models after the minimization of equation (11) and the number of objective function evaluations (NFE) involved in the parameter identification. Four systems were selected as benchmarking examples to illustrate the numerical performance of FPA and MFPA in the parameter estimation for LLE modeling.…”

“…Em outras palavras, a temperatura do reator não interfere nas frações produzidas pela reação já que a conversão dos reagentes foi fixada no próprio equipamento em 50% do reagente etanol. Portanto, a temperatura do reator foi alterada para 20°C em vez de 40°C, temperatura original da simulação, para que fosse possível comparar os dados obtidos na simulação com os dados experimentais disponíveis para o ELL do ternário (MERZOUGUI et al, 2011 A Tabela 3 apresenta os erros relativos médios para os pontos da binodal. Os erros obtidos para as frações de água em ambos os modelos são semelhantes, mas para as outras frações os valores apresentados são bastante diferentes.…”

“…Then, the concentrations of the acid in both the phases were obtained by potentiometric NaOH titration [6]. Besides, the water content of the organic phase was measured by the Karl-Fisher method [6] and the water contained in the aqueous layer was determined using refractive index measurement method [8]. The obtained tie line data for (water þ phosphoric acid þ methyl isoamyl ketone (MIAK)) [9] and (water þ phosphoric acid þ dichloromethane (DCM)) [10] ternary systems are presented in Figure 2 and Table 1, respectively.…”
