The merit of each characterization procedure is evaluated through vapor-liquid equilibrium, phase separation and volumetric calculation. The methods are evaluated using information from literature for a twenty-component mixture. A commercial software was used to determine the true boiling points of the mixture and the Soave-Redlich-Kwong equation of state was used for vapor-liquid equilibirum calculations. In the three methods, the mixture is separated into six pseudo-components. It is found thaat the best characterization method is the one which directly uses the true-boiling point curve to obtain the pseudo-components.
