1.16: Methods for Separating Mixtures
Distillation is an effective method to separate mixtures that are comprised of two or more pure liquids. Distillation is a purification process where the components of a liquid mixture are vaporized and then condensed and isolated. In simple distillation, a mixture is heated, and the most volatile component vaporizes at the lowest temperature.
Separation Equipment
The shortcut distillation method, the so-called Fenske-Underwood-Gilliland method, enables design calculations of distillation columns. Azeotropic and extractive distillations are used to separate mixtures with low relative volatility or azeotropic mixtures. Reactive distillation combines chemical reaction and distillation in single equipment.
