<onlyinclude>'''Distillation''' is the process of separating the components or substances from a liquid mixture by using selective boiling and condensation. In industrial applications, distillation is a physical separation process, not a chemical reaction. The distillation of fermented products produces distilled beverages with a high alcohol content, or separates other fermentation products of commercial value.</onlyinclude> | <onlyinclude>'''Distillation''' is the process of separating the components or substances from a liquid mixture by using selective boiling and condensation.

=== Origin and composition === | |||
The distillation method is used to separate different components from a liquid mixture via a thermophysical separation. The feedstock for the distillation process normally is coming from a process with different products and it is used to seperate those into homogenous product streams. Distillation also is an effective and traditional method of desalination. | |||
=== Pre-treatment === | === Pre-treatment === | ||
For a distillation no specific pre-treatment is needed since it is used to separate different fraction within a process chain. Sometimes it is combined with other separation technologies. | |||

Dry distillation is the heating of solid materials to produce gaseous products (which may condense into liquids or solids). Dry distillation may involve chemical changes such as destructive distillation or cracking and is not discussed under this article. Distillation may result in essentially complete separation (nearly pure components), or it may be a partial separation that increases the concentration of selected components in the mixture. In either case, the process exploits differences in the relative volatility of the mixture's components. | Dry distillation is the heating of solid materials to produce gaseous products (which may condense into liquids or solids).
