Abstract

Partial mixing of a liquid in cross motion of the phases is considered. Part of the liquid (ϕ) on a plate is totally mixed, while the other part (1 − ϕ) moves in the regime of ideal displacement; the degree of mixing is determined by the relation of these parts. The composition of a vapor after the plate is taken to be equal to the average value of the compositions of the vapor that come out of the initial and final portions of the plate in the direction of liquid motion. After an ideal plate these compositions are in equilibrium with the arriving and leaving liquid, respectively. The analytical dependences of the efficiency on the parameters of a real plate are obtained. The equality of the efficiencies in the vapor and liquid phases is proved. Certain particular and limiting cases of applicability of the complex model are considered.
