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.
