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
