Title: An equation of state for property prediction of alcohol-hydrocarbon and water-hydrocarbon systems

Abstract: Equations of state have been widely used in the petroleum and chemical industries for thermodynamic property calculation. in the presence of polar substances that self-associate through hydrogen bonding (such as water or alcohol), equations of state are of very limited use. One way to account for the association is to consider the equation of state to be formed of two contributions: physical and chemical. In this work, we develop an equation of state consisting of two terms as proposed by Andreko [Fluid Phase Equilib. 65 (1991) 89], a chemical and a physical term, for correlation of thermodynamic properties of mixtures containing an associating species. This equation of state is used to correlate vapor pressure data for a number of associating molecules, such as alcohol and water, as well as bubble point pressure data for binary water-hydrocarbon and alcohol-hydrocarbon systems. The results obtained are in good agreement with the experimental data and requiring the use of only one adjustable parameter for each binary system. (C) 2001 Elsevier Science B.V.
