Sažetak
The extraction of soybean oil from the surface of spiked quartz sand using supercritical CO2 was investigated. Sand as solid was used; it is not porous material so the internal diffusion does not exist, all the soluble material is in the surface of the particles. Sovová’s model has been used in order to obtain an analytical solution to develop the required extraction yield curves. The model simplifies when the internal diffusion can be neglected. The external mass transfer coefficient was determined by fitting the theoretical extraction curve to experimental data. According to the external mass transfer coefficient, a new Sherwood correlation was developed in terms of the dimensionless groups: Reynolds and Schmidt number. It was found that this correlation give superior results when compared to experimental data.
