T–x–y vapour–liquid equilibrium — ethanol/water at 101.3 kPa with azeotrope
Binary temperature–composition VLE diagram for ethanol and water at atmospheric pressure showing the bubble-point and dew-point curves and the minimum-boiling azeotrope at 0.894 mole fraction ethanol and 78.15 °C, the phase-behaviour figure a separations engineer needs before specifying a distillation or dehydration scheme.
