Resumen
ESPINOSA, S.; DIAZ, M. S. y BRIGNOLE, E. A.. Process optimization for supercritical concentration of orange peel oil. Lat. Am. appl. res. [online]. 2005, vol.35, n.4, pp.321-326. ISSN 0327-0793.
This work addresses modeling, simulation and optimization of countercurrent deterpenation of orange peel oil, modeled as a model mixture of limonene-linalool, with supercritical carbon dioxide as solvent. Binary and ternary systems are modeled with a group contribution equation of state, and vapor-liquid equilibria and selectivity predictions are compared to experimental data from different sources. A nonlinear programming model is proposed for the maximization of net profit. Process simulations are carried out at conditions reported in the literature and component purity and recovery in the output streams are contrasted against laboratory-scale process results. Optimization results provide operating conditions and equipment size to maximize net profit.
