Methanol water separation by distillation

Experiment #2: Distillation CHEM 213 – Fall 2009 Distillation is an inexpensive and relatively simple technique used to purify liquids. Chemists often use this method to separate homogeneous solutions of two or more liquids. In industry, distillation is used to separate the Equilibrium Separation Column In equilibrium separation processes, two or more coexisting zones are created with preferential distribution of the different components involved in the process in each zone. For example, in distillation a liquid and vapor zones are created and the components are separated in different proportions between these zones. In the current study, a novel approach for separating ethanol-water mixture by microbubble distillation technology was investigated. Traditional distillation processes require large amounts of energy to raise the liquid to its boiling point to effect removal of volatile components.
