“…De La Garza et al are credited with the initial theory of a MARC for overall separation factors close to unity (5,6). Later the theory was broadened for the case of arbitrary separation factors (7,8,(10)(11)(12).…”

The possibility of estimating the minimum total flow in a cascade with concentrations of a target component given in the product and waste flows by means of a model match abundance ratio cascade (MARC) is studied. The parameters required to describe MARC characteristics are the total number of separation stages, the feed flow location, and the M Ã parameter, which is equal to a half-sum of mass numbers of the target and the supporting components. Specific research carried out independently in two scientific labs in China and Russia has demonstrated that the integral parameters of the MARC, optimized by the M Ã parameter, are very close to that of the optimum by the minimum total flow cascade found by means of numerical optimization. The calculation is performed for separation of krypton isotopes when the end component 78 Kr and the intermediate component 83 Kr are considered to be the targets. It paves the way to use the optimized MARC parameters for two purposes: first, for fast and easy evaluation of the real cascade parameters and second, as an initial guess in its further direct numerical optimization, thereby allowing significant savings in computation time.

“…As is known, the model cascade theory is widely used to study the regularities of the multicomponent selective mass transfer in separation of multicomponent isotope mixtures in cascades (Sulaberidze et al, 2006;De la Garza et al, 1961;De la Garza, 1963;Yamamoto and Kanagawa, 1987;Wu and Fu, 1998;Von Halle, 1987;Agostini, 1994;Zeng et al, 2012;Scopatz, 2013;Wood and Megliorini, 2012;Song et al, 2010). On the base of this theory, it was demonstrated the fundamental possibility of obtaining relatively high concentrations of intermediate components in the additional product flow within the cascade having an "extension" of a working substance flow at its internal stage.…”

“…The concept of the model continuous profile cascades for separation of multicomponent mixtures has been developed in the middle of 1960s (De la Garza et al, 1961;De la Garza, 1963;Levin, 1963). This concept was further developed by the Russian scientists in 1970s (Kolokoltsov et al, 1970(Kolokoltsov et al, , 1973Kolokoltsov and Sulaberidze, 1971).…”

“…There exist two main types of model cascades, which are a "quasi-ideal" cascade with arbitrary enrichments (Yamamoto and Kanagawa, 1978;Sazykin, 2000) and a Q-cascade with "weak" enrichments (Kolokoltsov et al, 1970) at cascade stages. The special case for both types is a Matched Abundance Ratio Cascade (MARC) (De la Garza et al, 1961;De la Garza, 1963;Von Halle, 1987). The incoming flows at the entrance to each stage of MARC have the same relative concentrations for the specified pair of components.…”
