Numerical Simulation and Experimental Study on Supercritical CO₂ Extraction of Red Pepper Seed

Abstract:

Numerical simulation and experimental study on the extraction of oil from red pepper seed using supercritical CO2 was performed in this study. Some main influence factors were investigated, including the influence of operation pressure and temperature on extraction yield Xe(%). A model equation was established based on mass transfer process, and the model equation was validated with the experimental data. The maximal and minimal relative errors between experimental data and numerical simulation value were 1.29% and 0.28% respectively. The results of 3-D simulations were obtained by associating extraction yield Xe(%) with operation temperature and pressure. As shown in the figures, it is obvious that there is an excellent agreement between the correlations results and the experimental data. Consequently, the optimum pressure and temperature were determined to be 20MPa and 318K respectively.
