Defintion (From Wikipedia)
Distillation is a method of separating chemical substances based on differences in their volatilities. Distillation usually forms part of a larger chemical process, and is thus referred to as a unit operation.
Distillation has a number of uses. It is used to separate crude oil into more fractions for specific uses such as transport, power generation and heating. Water is distilled to remove impurities, such as salt from sea water. Air is distilled to its components such as oxygen for medical applications and helium for party balloons. The use of distillation on fermented solutions to produce distilled beverages with a higher alcohol content is perhaps the oldest form of distillation, known since ancient times.
An introduction on distillation site for fresh engineer and refresher for experienced engineer being maintained by M.T. Tham from Department of Chemical and Process Engineering at the University of Newcastle, Tyne, UK.

The purpose of below notes is to expose you to the terminology used in distillation practice and to give a very basic introduction to:

Restek has presented some distillation theory and practice related stuff such as CLAUSIUM-CLAPEYRON equation, TROUTON's rule, RAOULT's Law, basic equiment, estimation of plate, compositional changes, Distillation Column, etc.

Will bring to you some industrial distillation related stuff next round...
