Batch distillation pilot plant DIS/EV

Batch distillation pilot plant DIS/EV designed to teach distillation principles and practical work with distillation systems. The device consists of a borosilicate glass distillation column with AISI 316 stainless steel mesh packing, a reboiler, a condenser and a reflux head. The distillate is collected in glass containers after cooling in a tubular heat exchanger.

The automated version (DISa/EV) has PID controllers that allow automatic adjustment of feed preheating temperature, condenser cooling water flow and vacuum level.

Training opportunities:

• Distillation of different mixtures (water/ethanol, water/methanol, methanol/propanol, etc.) by changing the following parameters:
  • return current ratio,
  • reboiler heating power,
  • feed composition,
  • pressure level.
• Preparation of mass and energy balances.
• Calculation of the theoretical number of pallets.
• Observation of tidal phenomena and hydrodynamics.
• Automatic flow, pressure and temperature control (DISa/EV only).
• Device monitoring via computer (DISa/EV only).
