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 packing present in the column multiplies the contact surface and thus the material transfers. A metering pump for introducing the solution at specific points in the column makes this unit operation continuous. The vapors are condensed and then distributed between the distillate (recovered continuously) and the reflux via a solenoid valve regulated on the column temperature. The residue is also recovered continuously from the bottom of the boiler. The temperatures at the bottom and at the top of the column are measured as well as at the points of introduction of the solution in order to establish the temperature profile.

Educational Objectives :

Study of the hydrodynamics of the column.
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
