Abstract :
Introduction: Supercritical fluid extraction (SCFE) is a promising technique that has been attracted by some scientist recently due to the moderate operational condition.Moreover, SCFE products are pure and free of residual solvents. Mathematical modeling of supercritical extraction is a useful tool for deducing the SCF extraction systems, prediction of optimum operational conditions and system design variables, and scale-up to the pilot and industrial scales. Materials and Methods: A new mathematical model modified by Sovova, based on the concept of broken and intact cells, has been applied to understand the variables effect on extraction efficiency in a SCF extraction system. System was made in order to extract the essential oil from orange peel. This model simulates the experimental data points adequately for two separate time using combined pattern of phase equilibrium equations, solute/matrix interaction and internal diffusion rules in the solid particles. Model equations for plug flow are ordinary differential equations and are solved by matlab using numirical method. A number of physical parameters have been determined by experimental data fitting.Results: Extraction curves have been presented on the form of extraction yield versus relative amount of passed solvent. The effect of operational parameters including grinding efficiency, bed void fraction, number of mixers and external mass transfer coefficient have been also investigated.Conclusion: The most desirable result is obtained from grinding efficiency and external mass transfer coefficient of 0.7 and 0.011 respectively, within 20 mixers. The model results present a good agreement with the experimental results. Average absolute deviation between experimental data and the modeling results is about 6%.
