Investigation of the effect of feed stage and first stage cut on the squared cascade performance to offer an appropriate strategy for separation of tellurium stable isotopes

Abstract

In the present work, the performance of a square cascade in the separation phase of tellurium stable isotopes is studied. In this cascade, the selection of an appropriate feed stage, the first stage cut, and the cut of the cascade are the effective parameters. The results showed that in the various separation factors, selection of the middle feed stage leads to appropriate results. Also, if the cut of the first stage is selected in such a way that the cuts of stripping section are obtained the same, it is one of the cut-offs for which the two grouping parameters of components will have the highest possible value. Based on the selection of this cut, one of the possible strategies available through using the code-named SQCASSIM for the separation of tellurium stable isotopes to the enrichment of more than 90% is presented.
