Abstract

The authors obtained generalized dependences for the heights of transfer units of ideal and actual steps that are expressed by the parameters of an actual tray in the vapor and liquid phases. The particular dependences of the heights of the transfer units equivalent to a theoretical tray that are expressed by the parameters of an actual tray in the vapor phase are presented for four variants of interrelation between the ideal and actual trays, two of which are characteristic of the Murphree model in analyzing the efficiency in the vapor and liquid phases and one of which is characteristic of the Hausen model. The ratio of the heights of the ideal and actual trays in all the variants is equal to the efficiency. It is noted that the expressions of the average moving forces, the mass-transfer coefficients, and the numbers of transfer units are individual for each variant and form of organization of phase motion, but in generalized form they are given by the existing dependences.
