"The process of separating liquids through differences in
their vapor pressures is called Distillation. In the
oldest method, the concentration of alcohol by the
application of heat we get the fermented liquid mixture.
Now this method is energy-consuming used for the
production of petroleum products in chemical industry
and other fields. The chemical properties of the mixture
are determined by the composition of vapor during liquid
Distillation is possible only when the component having
higher vapor proportion than the mixture. With other
components, the given component having a higher vapor
pressure and a low boiling point."
