Principle of operation :

Distillation allows the separation of a mixture of compounds having different boiling points. The boiling of the mixture makes it possible to obtain vapors of compositions different from the liquid. Re-condensations and multiple re-evaporations progressively enrich the vapor phase to the most volatile product. The vapors are condensed and then distributed between the distillate (recovered continuously) and the reflux via a column head valve. The residue is also recovered continuously from the bottom of the boiler.

Educational Objectives :

Study of the hydrodynamics of packed columns and perforated tray columns.
Continuous distillation.
Azeotropic continuous distillation.
Comparison of packed columns and perforated tray columns.
Influence of the operating conditions on the separation of a binary solution
Thermal balances.
Material balance.
Determination of the number of theoretical plates (McCabe and Thiele, Ponchon and Savart).
Determination of the number of transfer units
