Description

DC Continuous Distillation Pilot Plant Vocational Training Equipment Chemical Engineering

The solution having to be distilled, stored in a glass tank, is sent to the distillation column by a metering pump after crossing a pre-heating exchanger. The column can be fed through 3 points at different height.

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:
• feed pre-heating temperature
• reflux ratio
• feeding flow rate
• reboiler heating power
• feeding composition
• residual pressure
• Mass balance
• Energy balance
• Flooding
• Calculation of the number of theoretical trays
