What is Distillation?

Distillation is a process of separating the component substances from a liquid mixture by selective evaporation and condensation. Distillation may result in essentially complete separation (nearly pure components), or it may be a partial separation that increases the concentration of selected components of the mixture. [1]

Basically, Distillation is the most important process in most of the industries, it is also one of the most complicated one. However, The Machines and Instruments that are used for Distillation process are quite costly require lots of energy.

To overcome this efficiency issue, there are some key changes & mechanism designed, which can be really helpful in energy conservation.

• Distillation permits separation of air into its components — notably oxygen, nitrogen, and argon — for industrial use.

• In the field of industrial chemistry, large ranges of crude liquid products of chemical synthesis are distilled to separate them, either from other products, or from impurities, or from unreacted starting materials.

• Distillation of fermented products produces distilled beverages with a high alcohol content, or separates out other fermentation products of commercial value.[1]

Furthermore, it has a great influence on the number of theoretical stages needed for the separation and the diameter of the column. Firstly, operating pressure affects the temperatures of heating and cooling. The bubble point and dew point temperatures of a mixture of a given composition depend strongly on pressure. For mixtures in which the vapor phase behaves as an ideal gas and the liquid phase behaves as an ideal liquid solution, Raoult’s law can be used, together with a suitable vapor-pressure model, to predict the pressure temperature relationships. For less ideally behaved mixtures, other fluid property models, including cubic equations of state and activity co-efficient models, are needed.
