A complex model is compared with the Murphree and Hausen 
models for the cases of concurrent and cross motion of vapor and liquid 
phases. Use is made of results of experimental studies involving separation 
of an acetic acid-water mixture and industrial data on rectification 
of furfurol and ethanol. It is proved that the efficiencies in the 
complex and Murphree models coincide as the coefficient of phase equilibrium 
m approaches unity but when this coefficient increases, the 
first model and the Hausen model coincide. The possibility of using 
the Murphree model at m  1 and the Hausen model at m   is shown.
