3. Introduction Distillation is a process in which a liquid or vapour mixture of two or more substances is separated into its component fractions of desired purity, by the application and removal of heat. Principle: Separation of components from a liquid mixture via distillation depends on the differences in boiling points of the individual components. And also depends on the vapour pressure characteristics of liquid mixtures.

4. Flash Distillation Flash Distillation is a process in which the entire liquid mixture is suddenly vaporized(flash) by passing the feed from high pressure zone to low pressure zone Flash distillation is used for separating components, which boils at very high temperatures. Moreover, it is a continuous process, used in multicomponent system. It is not efficient for pure components.
