Abstract

A proper description of the physical properties of the petroleum fractions in hydrocarbon mixtures is essential in performing reliable phase behavior calculations and compositional modeling studies. This paper presents a comparison study among nine different correlations used to calculate the molecular weight of undefined petroleum fractions. A new correlation was developed for calculating the molecular weight of undefined petroleum fractions as a function of boiling point with an average error of 0.4 %, standard deviation of 0.6 % and correlation coefficient of 0.99991.
