Description

LL Liquid-Liquid Extraction Pilot Plant Teaching Education Equipment for School Lab Chemical Engineering

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
