Modeling of the Extraction Process of Tea Seed Oil With Supercritical Carbon Dioxide

Abstract

-The kinetics of the extraction of tea seed oil with supercritical CO 2 was studied. A kinetic model of the extraction of tea seed oil using supercritical CO 2 was developed on the basis of the differential mass balance to simulate the extraction process. The model could simulate the distribution of the solute concentration in CO 2 inside the extraction bed as a function of extraction time and height of the extraction bed. The model could also simulate of the solute concentration in CO 2 at the outlet of the extractor as a function of time. The effects of the parameters such as pressure and temperature on extraction yield and the process were investigated through the model. This model could simulate satisfactorily the process of extraction with an error between simulation data and experimental data of less than 10%.
