Continuous Distillation Pilot Plant vocational education equipment

BDC Continuous Distillation Pilot Plant vocational education equipment

The solution having to be distilled, stored in a tank of plastic material, is sent to the distillation column by a metering pump after crossing a pre-heating exchanger.
The distillation column is completely of glass and it consists of a reboiler, of a sieve-tray column and of a condenser with reflux head and valve.
The bottom product and the distillate are collected into two tanks after being cooled by two heat exchangers.
Training program
This unit enables to deepen the following issues:
• Distillation of different mixtures (water / ethanol, water / methanol, methanol / propanol, etc…) at atmospheric pressure, versus the variation of the following operational parameters:
• reflux ratio
• feeding flow rate
• feeding composition
• Mass balance
• Energy balance
• Flooding

• Calculation of the number of theoretical trays
