Definition - What does Distillation mean?

Distillation is a separation technique, where substances are removed from a fluid mixture by evaporation and condensation. The distillation method can be either complete or partial. The process usually separates component substances from the fluid mixture. Distillation is used in many commercial industries for various applications.

Corrosionpedia explains Distillation

The oil industry uses a distillation unit as the primary process to obtain different types of petroleum products. The crude oil is heated and passed through a distillation unit using a variety of mediums and techniques.

Similarly, in a water distillation process, separating the water from the liquid mixture and other volatile components can be performed either by heating the mixture or without heating the mixture. Heating involves converting the mixture into vapors, then cooling and condensing these vapors. The components of the liquid mixture are separated out by partial vaporization, and then the vapors and liquid residue is collected. The more volatile components such as water are converted into a vapor state by this process, which is subsequently condensed or purged to the atmosphere.
