Abstract

Consideration is given to a tray liquid in the intermediate state between ideal displacement and total mixing, for which purpose the degree of attaining the latter state by the liquid is introduced. The composition of the vapor after leaving an ideal tray is assumed to be in equilibrium with that of the liquid in its intermediate state. Four variants of interrelation of the real and ideal trays are considered; the efficiencies for the vapor and the liquid are proved to be equal for each of them. Ratios for the efficiencies of all the variants are obtained. A comparison is made of the efficiency ratios as functions of liquid mixing.
