PHASE BEHAVIOR PREDICTIONS FOR CARBON DIOXIDE + ISOPROPANOL BINARY SYSTEM WITH A CUBIC EQUATION OF STATE

Abstract The purpose of this paper is to demonstrate the ability of a cubic equation model to predict the phase behavior of the carbon dioxide (1) + isopropanol (2) binary system. A single set of binary interaction parameters for each EoS, determined for the carbon dioxide + 2-butanol binary system,...

Summary:Abstract The purpose of this paper is to demonstrate the ability of a cubic equation model to predict the phase behavior of the carbon dioxide (1) + isopropanol (2) binary system. A single set of binary interaction parameters for each EoS, determined for the carbon dioxide + 2-butanol binary system, was used to model the global phase behavior of the system. Instead of correlating the experimental data, we used a predictive approach. [...]the GEOS equation was used in a semi-predictive approach to obtain a set of binary parameters yielding good results in the binary system carbon dioxide + 1-propanol (including VLE in the entire temperature range, critical points, global phase behavior) [14].
