In this work, we have formulated a series of nonlinear programming models based on first principles and rigorous thermodynamic predictions, to perform economic evaluation for different scheme alternatives in supercritical methanol transesterification for biodiesel production. The model includes thermodynamic predictions with a group contribution equation of state that have been favorably compared, in this work, to the available experimental data for the different mixtures at different operating conditions. The resulting nonlinear programming problem for cost minimization has been solved with a successive quadratic programming algorithm. Numerical results indicate that the use of a heat pump within the noncatalytic biodiesel production scheme significantly reduces operating costs, making this technology economically competitive as compared to conventional ones. 6 Energy & fuels 23 ARTICULO Díaz, M.S. 42293 Espinosa, S. 42294 Brignole, E.A. 42295 170795 170795 0 0 0 0 238614 BAAB BAAB 2026-03-05 200045649 0 200045649 2026-03-05 15:12:59 2026-03-05 ARTICULO
