MODELING OF SUPERCRITICAL FLUID EXTRACTION KINETIC OF FLAXSEED OIL BY DIFFUSION CONTROL METHOD

34101

In this study, Flaxseed oil was extracted by Supercritical Carbondioxide Extraction, and extraction kinetics was modelled using diffusion controlled method. The effect of process parameters, such as pressure (20, 35, 55 MPa), temperature (323 and 343 K), and CO2 flow rate (1 and 3 L CO2 /min) on the extraction yield and effective diffusivity (De) was investigated. The effective diffusion coefficient varied between 2.4 x10^-12 and 10.8 x10^-12 m^2s^-1 for the entire range of experiments and increased with the pressure and flow rate. The model fitted well the experimental data (ADD varied between 2.35 and 7.48%).
