Abstract

The concepts of mass and heat transfer are applied to derive the equations of Murphree and vaporization point efficiencies with an approximation in which the linear relationship of vapor-liquid equilibrium is assumed. Characteristics of the efficiencies, including the effects of liquid composition upon the distillation point efficiencies, importance of thermal effects in evaluating the mass transfer coefficient from observed data, and accuracies of the equations are examined with numerical examples of a binary system and a ternary system.
