Abstract: | The distribution of components along the distillation column height in distillation of binary and ternary mixtures is studied at different profiles of liquid holdup in the system. It is shown that physical modeling of continuous and batch distillation at infinite reflux ratio without taking into account the liquid holdup distribution may be inadequate to the real process. Equations for the curvilinear equilibrium line are proposed, which relate the number of transfer units, the number of theoretical separation stages, and the component concentration.Translated from Teoreticheskie Osnovy Khimicheskoi Tekhnologii, Vol. 39, No. 1, 2005, pp. 3–6.Original Russian Text Copyright © 2005 by Lotkhov, Dil man, Lipatova, Kvashnin, Kulov. |
