Four regions of the complex mass-exchange model, the boundary 
cases of which are the Murphree model in analysis of the efficiencies 
in the vapor and liquid phases, the Hausen model, and the hypothetical 
model, are distinguished depending on the values of the distances 
h and h1. The limits of variation of h and h1 are found in each region. 
The dependences of h and h1 on the activity coefficients of highly volatile 
and involatile components and the equilibrium constant are substantiated.
