【摘要】 针对超临界流体萃取土壤污染物的传质过程数据的缺失,分析了当前超临界流体萃取模型的优缺点,并在超临界流体萃取土壤污染物的过程是内扩散控制过程的基础之上,建立起基于微分床单元的质量守恒模型,再对模型进行求解与分析从而来模拟超临界流体萃取土壤污染物的传质过程。更多还原

【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.更多还原
