MASS-EXCHANGE MODELS WITH DIFFERENT
EQUILIBRIUM DEPENDENCES

The efficiency of mass exchange in the complex and hypothetical 
models and in the Murphree and Hausen models for concurrent and cross 
motions of the vapor and liquid phases has been compared with the 
use of equilibrium dependences of the y = mx and y = ax + b type. 
Industrial data on separation of furfurol-water and ethanol-water 
binary mixtures have been employed in the calculations. Satisfactory 
convergence of the results has been obtained.
