EXCHANGE IN THE COMPLEX MODEL FOR HIGHLY
VOLATILE AND NONVOLATILE COMPONENTS

The efficiencies of mass exchange in the complex model
have been compared for two variants of representation of the running
equation of the equilibrium line: *y* = *mx* and *y* = *ax* + *b*. Based on
the processing of experimental data on separation
of the benzene-toluene mixture in cross motion of the flows, it
has been shown that the first equation is adequate only for small
variations in the concentrations at the step of mass-exchange while
the second equation has a more universal character.
