Distillation allows the separation of a mixture of compounds having different boiling points. The boiling of the mixture, introduced initially into the boiler, 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. The vapors are condensed and then distributed between the distillate and the reflux via a manual flow control valve. The residue is recovered at the end of the operation.
The temperatures at the bottom and at the top of the column are measured as well as half of the column 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 solution.
  • Thermal balance.
  • Material balance.
  • Determination of the number of theoretical plates (Mc CABE and THIELE, PONCHON and SAVARIT).
  • Determination of the number of transfer units.
Technical specifications :

Equipment
 

  • Boiler made of borosilicate glass, electric heating, equipped with a minimum safety level and maximum temperature safety.
