Distillation

Distillation is that operation for mass transport, which, by exploiting the differences of vapor voltages, separates a liquid solution in order to obtain pure components or, more generally, two phases one of which is rich of lighter components (with higher vaour voltage) and the other is rich of heavier components. Distillation is an operation which involves solutions of different substances which are all relatively volatile at operating conditions.

Educational programme main experimental tests:

Study of the separation at variations of the following operating conditions:

Ø      Feeding flow

Ø      Feeding temperature
