Bubble point measurements for the ternary system carbon dioxide, benzene and naphthalene

Abstract

Bubble point pressures data were measured for the system carbon dioxide, benzene and naphthalene at 40, 60 and 80°C. The experimental points were determined for three constant mole ratios of benzene to naphthalene of 9:1, 9:2 and 9:3. The resulting experimental data were modeled using the Peng-Robinson equation of state. Two temperature independent interaction parameters k ij and l ij were used to obtain a relatively good agreement between the calculated and experimental data.
