摘要：

The experimental equilibrium solubility of ethylene glycol in supercritical carbon dioxide was measured by the static method at temperatures between (313.15 and 353.15) K and pressures up to 19.0 MPa, and the effects of temperature and pressure on the solubility were investigated. The experimental results show that the solubility ranged from ethylene glycol mole fraction of 0.83.10(-2) (353.15 K, 7.0 MPa) to 4.2940(-2) (353.15 K, 19.0 MPa), and the solubility increased with increasing pressure at a constant temperature, but a crossover pressure point (about 16.0 MPa) has been observed in the solubility isotherms at the temperature range from (313.15 to 353.15) K. Moreover, the experimental results were correlated with the Peng-Robinson equation of state using the quadratic mixing rules of the two-fluid van der Waals (vdW2) as well as the modified associative model; both correlations demonstrated satisfactory results, with an average absolute relative deviation (AARD) less than 5 %.
