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.
