Technical Specification

A laboratory liquid / liquid extraction column designed for use with Kerosene (Paraffin) and Acetic
acid.
Touch panel for control / calibration  of pumps and display of measurements
Recommended system uses water to separate Acetic acid from Kerosene
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 Kerosene system, (the used Kerosene can be disposed of, or else reused by performing a simple assay and topping up with acetic acid)
