Liquid-Liquid Extraction Pilot Plant Educational Training Equipment

LL1a Liquid-Liquid Extraction Pilot Plant Educational Training Equipment

This unit includes two separate tanks for the solvent and for the phase having to be refined, that are sent to the extraction column by two metering pumps; the column is provided with top and bottom phase separators and with two other tanks for collecting the refined and extracted products.
TRAINING PROGRAM
This unit enables to deepen the following issues:
• 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 (for mod. LL1a, only)
• Plant supervision by P.C. (for mod. LL1a, only)
TECHNICAL SPECIFICATIONS:
LL1a
Besides being provided with all the technical specifications of mod. LL and of mod. LL1, this model also includes the following additional items:
• Electronic level transmitter of AISI 316 stainless steel, differential pressure type, with range of 0 to 200 mm H2O, 4-20 mA output signal
• 3 electropneumatic converters 4 to 20 mA/0.2 to 1 bar
• Microprocessor digital PID controller with serial card
• Supervision software for Windows: it enables to control ON-OFF signals, analog signals coming from the PID controller, real-time trend and historical trend
