PIGNAT Continuous Distillation – DVI3000


SKU: DVI3000 Category: Tags: , ,


Operate a continuous distillation process

The distillation process separates several volatile liquids, simple or complex mixtures, by a series of vaporization and condensation steps. A number of liquids may be separated in this way if their boiling points are sufficiently different. Continuous distillation separates a mixture into fractions: a volatile fraction, the distillate extracted at the column head and a heavy fraction, the residue extracted at the bottom of the column.


  • Hydrodynamic study of the column to determine overflooding conditions and/or determine packing factor
  • Operate a continuous process to determine materials balance, thermal balance, yield, productivity.


  • Feed rate, preheating temperature, reflux ratio, and column pressure drop can be manipulated
  • The unit can work in batch or in continuous and with a vaccuum

Proposed Experiments:

  • Technical data:
    • Column hydrodynamics with water
    • Rectification of a binary water-ethanol mixure
  • Operations in continuous mode:
    • Study of a packed column
    • Determine the efficiency of the column by the McCabe-Thiele method (number of theoretical plates).
