  Abstract:   The ability of different thermodynamic models to predict the phase behaviour of carbon dioxide (1) 1,2-dimethoxyethane (2) binary system is tested. The model chosen is the General Equation of State (GEOS) coupled with classical van der Waals mixing rules (two-parameter conventional mixing rule, 2PCMR). Comparisons were made with the GEOS3C, Soave-Redlich-Kwong (SRK), and Peng-Robinson (PR) cubic equations of state (EoS) too. A single set of binary parameters for each model was used to predict correctly the global phase behaviour of the system. 

Keywords: carbon dioxide, 1,2-dimethoxyethane, high-pressures, vapour-liquid equilibrium, equations of state, GEOS, GEOS3C
