| Abstract: | It is necessary to build a reliable dynamic model for designing an extraction plant and optimizing operation conditions. This paper summarized and discussed mechanisms and dynamic models of supercritical fluid extraction of oils from different vegetable seeds. The general hypotheses of mathematical model of the extraction, mass transfer force and resistance in extracting were given. Overall volumetric mass transfer rates and correlation of parameters of the models were discussed in detail. |
