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.
