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 the column.
  • Influence of the operating conditions on the separation of a binary solution
  • Remote process control by an industrial supervisor.
  • Thermal balances.
  • Material balance.
  • Determination of the number of theoretical plates (McCabe and Thiele, Ponchon and Savart).
  • Determination of the number of transfer units
Technical specifications :

Equipment : 

  • Storage can of the polyethylene feed solution.
  • Feeder dosing pump, 316L stainless steel - PTFE. with remote control.
  • Feed preheater with two valves for 33% or 66% column feed, equipped with minimum level safety and maximum temperature safety.
  • Continuous boiler in borosilicate glass, electric heating, equipped with minimum safety level and maximum temperature safety.
  • Refrigerant for differential pressure test.
  • Column in borosilicate glass, in three elements with lining.
  • Three stainless steel 316L recentering trays, each equipped with a sampling valve and temperature sensor.
  • Borosilicate glass column head, with temperature measurement, equipped with a timer valve to control the reflux ratio.
  • Vertical condenser made of 316L stainless steel.
  • Two refrigerants of distillate and residue in 316L stainless steel.
  • Recipe for borosilicate glass distillate.
  • Recipe for borosilicate glass residue

  • 316L stainless steel connection pipes.
  • Support frame in 304L stainless steel tubes and aluminum nuts.


Instrumentation :

  • Condenser cooling water supply equipped with a float flowmeter with its control valve and a water circulation controller to stop heating due to lack of cooling.
  • Measurement of pressure loss of the column.
  • Industrial Supervisor with real-time process visualization, data acquisition and remote instrumentation control.
  • Control and control cabinet, IP55, equipped with emergency stop, operating buttons and the following interfaces:
  • Communicating preheater temperature controller.
  • Temperature regulator of the communicating column head.
  • Heating controller of the communicating boiler.
  • Control regulator of the communicating supply pump.
  • Digital converters of four Pt100 Ω probes (column temperature profile) communicating.
  • Two digital temperature indicators of 12 probes type Pt100 Ω including a communicating.
Options :
Option 1: Touch screen to view temperatures and control the regulators. With data storage and data recovery on USB stick in .txt files.
