A Research on the Process Simulation of the Supercritical Fluid Extraction of the Vegetable Oils

摘要

In this work, the process simulation of supercritical fluid extraction of solid material and its development are expounded. The representational kinetic models and the advantages and disadvantage for each one are particularly introduced. Because of the models are immature, the most popular one is discussed, and the improvements of its disadvantages are given. Based on the broken-intact cells model, a new differential mass balance equation is presented. The initial and boundary conditions are obtained by the analysis the process and the acceptable hypotheses, and the numerical solution of the model is given.
