Distillation - an overview | ScienceDirect Topics

Introduction. Distillation is the most commonly used method for the separation of homogeneous fluid mixtures. Separation exploits differences in boiling point, or volatility, between the components in the mixture. Repeated vaporization and condensation of the mixture allows virtually complete separation of most homogeneous fluid mixtures.
