Description

DIS Batch Distillation Pilot Plant Vocational Education Equipment for School Lab

The distillation column is completely made of glass and it consists of a reboiler, of a column with steel mesh packing and of a condenser with reflux valve and head.

Training program

This unit enables to deepen the following issues:

• Distillation of different mixtures (water / ethanol, water / methanol, methanol / propanol, etc…) versus the variation of the following operational parameters:
• reflux ratio
• reboiler heating power
• feeding composition
• residual pressure
• Mass balance
• Energy balance
• Flooding
• Calculation of the number of theoretical trays
