Phase equilibria of the propylene glycol/CO2 and propylene glycol/ethanol/CO2 systems

- Solubility of CO2 in the binary system of PG/CO2 under high pressure.
- Measurements were performed from 2.5 to 55.0 MPa at 398.2, 423.2 and 453.2 K.
- Solubility of CO2 in the ternary system of PG/EtOH/CO2 under 15 MPa of pressure.
- Measurements were performed at temperatures of 398.2, 423.2 and 453.2 K.
- Calculation of distribution coefficients (K′) and separation factors (α12).
