| Abstract: | Aim at the lack of mass transfer process data of supercritical fluid extract soil contaminants, this paper analyzes the advantages and disadvantages of the current model of supercritical fluid extraction. And on the basis of the process of supercritical fluid extract soil contaminants is the process of the diffusion-controlled process, the paper establishes a mass balance model based on the differential bed, and then solves and analyzes the model in order to simulate the mass transfer process of supercritical fluid extract soil contaminants. |
