Experimental Study and Modeling of Phase Equilibrium of the Methanol–Tripalmitin System: Application to Palm Oil Transesterification with Supercritical Methanol

摘要: The phase behavior of the methanol–palm oil system was first experimentally assessed in temperature range 363–393 K and pressure 1–4 MPa. Second, comparative modeling equilibrium methanol–tripalmitin performed using Peng–Robinson equation state (PR EoS) with second-order modified Huron–Vidal (MHV2) mixing rules, combination universal functional activity coefficient model (UNIFAC) quasi-chemical (UNIQUAC) excess Gibbs free-energy model. agreement between experimental results found to be satisfactory when MHV2 rules are used UNIQUAC Finally, thermodynamic applied predict fluid equilibria palm transesterification supercritical methanol. From isochoric method 373–693 1–16 MPa, global mixture behavior.
