Squared-off cascade with a given concentration of the target component in external streams

Abstract

The paper presents a method developed for calculating a squared-off cascade with several types of stages along the feeding stream. The method minimizes the total feeding stream of the cascade. Calculations of germanium tetrafluoride separation in cascades with different numbers of sections have been performed. Using the example of ⁷⁰Ge concentration, the optimal three-section cascade is demonstrated as effectively approximating the conical profile of R-cascade streams.
