Use of the Q-cascade in calculation and optimization of multi-isotope separation

Transient processes in Q-cascades for separation of multicomponent mixtures

“…Also, it was shown that the model cascades composed of stages with low enrichments, while optimized in the minimum total flow possess the parameters which are practically coincide to that of the optimum cascade providing a target component with a given concentrations in its product and waste flows Zeng et al, 2011;Sulaberidze et al, 2008). Given the above, one can conclude that the obtained in this study assessment determines the minimum possible time of separation cascade transfer to its stationary mode of operation.…”

“…Considering that the total flow of a working substance in the cross-section where a feed flow enters to the cascade is equal to (Kolokoltsov et al, 1970;Zeng et al, 2011Zeng et al, , 2012Tolstoy, 2010) …”

“…The incoming flows at the entrance to each stage of MARC have the same relative concentrations for the specified pair of components. The research on the Q-cascades acquires a second wind at the beginning of the 21st century Zeng et al, 2011Zeng et al, , 2012Zeng et al, , 2013Tolstoy, 2010;Smirnov and Sulaberidze, 2013). It allowed us, in particular, to identify the physical nature of a Q-cascade (Zeng et al, 2012), to demonstrate the physical equivalence of a Q-cascade and a "quasi-ideal" one, to study the regularities of molecular selective mass transfer in a Q-cascade in the presence of loss of working substance at its stages (Zeng et al, 2013;Smirnov and Sulaberidze, 2013).…”

Application of the Grey Wolf Optimization Algorithm to Separate Middle Components in Multicomponent Mixtures

“…GCs are arranged in a square and taper configuration in separation cascades. In taper cascades, model cascades such as Q, R, and quasiideal are used to design the cascade, and the designed cascade can separate only one isotope [1][2][3]. So, the cascade cannot be applied for other isotopes; to do this; the configuration of cascade single-cascade optimization has been alone, and there is only one multi-cascade optimization to achieve high concentrations for middle isotopes [8].…”
