Distillation is a process including heat and material transfers in order

to separate one or several products of relative different volatility.

The separation is carried out by a chaining of vaporizations and condensations.

The theoretical base is that a vapor produced from a mixture is in equilibrium with

the mixture liquid phase and has generally a higher composition in the most volatile compound.

The separation is carried out in a column (packed or plates column) designed to get the best

contact and material exchanges between the climbing vapor and the falling liquid into the column.

This separations can be done in continuous or discontinuous (batch) process.
