This work intend to model supercritical fluid extraction of Rosemary essential oil (Rosmarinus officinallis l.) obtained at 310.15 and 320.15 K at 100, 120, 140 and 160 bar and to analyze the parameters and the objective function with statistic tools. We have been used the finite differences method to solve the model, the parameters were estimated using the maximum-likelihood method. The results have shown that the model can reproduce the experimental data of supercritical fluid extraction.
