Description
This plant consists of a liquid-liquid extraction column of glass with rotating discs installed aside a distillation column. This last column can be used to recover the solvent used for the extraction, or separately for the study of distillation process. The automated version is equipped with 2 PID controllers enabling to control the level in the extraction column and the flow rate of the water cooling the condenser of the distillation column.
TRAINING PROGRAM
This unit enables to deepen the following issues:
Extraction
• Determination of the number of transfer units
• Height of a transfer unit
• Extraction efficiency
• Mass balance
• Calculation of mass transfer coefficient
• Calculation of the number of theoretical stages
• Trend of concentrations along the column
• Exercises on systems of 3 partially mixable components:
- acetic acid – toluene – water
- acetic acid – isopropyl ether – water
- acetic acid – ethyl acetate – water
• Automatic control with PID controller
• Plant supervision by P.C.
Distillation
• Recovery of the solvent used in the extraction
• Distillation of different mixtures (water / ethanol, water / methanol, methanol / propanol, etc...) versus the variation of the following operational parameters:
- reflux ratio
- feeding flow rate
- reboiler heating power
- feeding composition
• Flooding
• Automatic flow control by PID controller
• Plant supervision by P.C.
