Liquid / Liquid Extraction Unit

Liquid / liquid extraction is important in chemical engineering where the separation of one or more of the components from a liquid mixture is required.

Liquid / liquid extraction is an important operation in chemical engineering where the separation of one or more of the components from a liquid mixture is required. Traditionally this has been difficult to demonstrate in the laboratory, requiring the use of highly toxic, expensive and / or environmentally damaging solvents. This system introduces a new approach using 1-Octanol or Canola oil which are safe, readily available and inexpensive.

Solvent temperatures: Ambient to 50°C, individually controllable
Pump rate: 0-13.5 l/hr
Feed rate: 0-3 l/hr
Rotation speed: 1 rev/15min (4 revs/hr)
Cell compartment: 0.16 l capacity

• Touch panel for control / calibration of pumps and display of measurements
• Recommended system uses water to separate Propionic acid from 1-Octanol
• Operation with the organic or the aqueous phase as the continuous phase inside the column
• Location of the phase boundary is predetermined by the density difference between the phases with no sensors or controls involved
• A single valve sets the organic phase or the aqueous phase as the continuous phase as required for a particular exercise
• Simple adjustment of lower phase boundary to compensate for variation in specific gravity of the organic phase
• Sensors measure the temperature and conductivity of the aqueous phase before and after the extraction process allowing the concentration of acid to be determined and the extraction efficiency to be calculated
• Includes PC software allowing data logging of measurements and calculation of acid concentration in the aqueous phase
• No solvent recovery system is necessary using the recommended organic solvent system
• Designed to handle 1-Octanol or Canola oil with a thermostat to limit maximum operating temperature for safe operation
• Pneumatic diaphragm pump used to minimise risk of ignition of the organic phase
