Extraction of Oil from Canola Seeds With Supercritical Carbon Dioxide: Experimental and Modeling

摘要

In this work extraction oil from canola (Brassica Napus) seeds with supercritical CO_2 extraction at pressure of 1500 to 2750 Psi, temperature of 308 to 333 k, and particles size 0.08 to 0.2 mm in flow rate 5 Lit/hr was investigated in a bench scale apparatus. The extraction was modeled by the sovova extended lack's model. The fluid phase mass transfer coefficient (kf), solid phase mass transfer coefficient (ks), and hardly accessible solute (x_k) were just able parameter of Models. The broken and intact cells model fit the experimental data, quite well, showing the applicability of the model to the supercritical extraction system studied here.
