Measurements and correlation of high-pressure VLE of binary CO 2–alcohol systems (methanol, ethanol, 2-methoxyethanol and 2-ethoxyethanol)

High-pressure vapor–liquid equilibrium (VLE) data were measured for binary CO 2–alcohol systems (e.g. methanol, ethanol, 2-methoxyethanol, and 2-ethoxyethanol) at various isotherms (313.15–345.15 K). The quantitative VLE data and mixture critical conditions were measured using a new design for a cir...

Summary:High-pressure vapor–liquid equilibrium (VLE) data were measured for binary CO 2–alcohol systems (e.g. methanol, ethanol, 2-methoxyethanol, and 2-ethoxyethanol) at various isotherms (313.15–345.15 K). The quantitative VLE data and mixture critical conditions were measured using a new design for a circulation VLE system. The measure data were correlated by the classical Peng–Robinson and the multi-fluid nonrandom lattice fluid hydrogen-bonding (MF-NLF-HB) equation of state. The MF-NLF-HB model was formulated previously by the present authors based on the proton donor–acceptor principle to the hydrogen-bonding interaction in CO 2–alcohol systems. For the measured and calculated data of CO 2–alcohol systems, the relative accuracy of the data was discussed.
