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.
