【 摘 要 】

It has been shown recently that Q-cascade with an expansion of the entering flow at the intermediate withdrawal point is able to obtain a concentration of an intermediate component far exceeding the concentration limit available from an end withdrawal. To enhance the applicability of this approach, it is necessary to reduce the relative total flow while maintaining the concentration of the intermediate target component unchanged. Optimization is carried out by using the technique of cascade segmentation, and using the mass numbers of the virtual components in the segments and the lengths of the segments as decision variables. The results demonstrate that the relative total flow is considerably reduced through optimization.
