A laboratory liquid liquid extraction column designed for use with Kerosene Paraffin and Acetic acid.
Organic phase circulation system with an 18l feed tank, 18l return tank and variable speed air operated pump. Pump is calibrated and gives flows of 50-250ml/min.
Column length 1.6m (1.2m working length), 50mm diameter, made from glass.
Column packed with 15mm glass Rashig rings.
Includes valves for taking samples of both phases for analysis.
Touch panel for control / calibration of pumps and display of measurements.
A single valve sets either the organic phase or the aqueous phase as the continuous phase .
Aqueous phase circulation system with a 25l feed tank, 25l return tank and variable speed pump. Pump is calibrated and gives flows of 50-250ml/min.
Fine adjustment of the lower phase interface to compensate for variation in specific gravity of the Kerosene.
Distillation column and distillation bridge with liebig condenser
Electrical bottom heating via pid controller
Operation as continuous or discontinuous process using 2 three-way valves
Glass extraction column
Water jet pump for reduction of evaporation temperature during distillation
Liquid-liquid extraction in counter flow operation with distillation for enrichment of the extract
2 valves for adjusting the phase boundary
2 pumps to deliver the feed and solvent
Stainless steel tanks for feed, solvent, raffinate, extract and top product (distillation)
Distillation column packed with Raschig rings.
