This work reports phase equilibrium measurements for the ternary system CO2 + glycerol + ethanol. Experiments were performed in a high pressure variable-volume view cell at temperatures ranging from 303.15 K to 343.15 K and pressures up to 26 MPa. The CO2 molar fraction varied from 0.1308 to 0.9871, and glycerol to ethanol molar ratios studied were 1:12, 1:20, and 1:30. For the systems investigated, vapor-liquid (VL), liquid-liquid (LL), and vapor-liquid-liquid (VLL) phase transitions were observed. Phase equilibrium data measured for the ternary system aim the better understanding of the phase behavior knowledge of the glycerol in the ethanol + CO2 mixture at high pressure system.
