On almost continuous regime of cascade of successively joint adsorbing apparatus

The sequence $K_n$, $n=1,2,\dots,$ of cascades of consecutive-joint sorption apparatus under periodic switching that approximated a continuous countercurrent sorption apparatus (column) $K_\infty$ has been considered. It was shown, that the sequence of solutions of mathematical models described the limit (settle) operating conditions of the cascades $K_n$, $n=1,2,\dots,$ uniformly converges to stationary solution of mathematical model of countercurrent column $K_\infty$. The result obtained is used in approximate description of $K_n$-cascades' operation.
