Liquid Liquid Extraction Unit Manufacturer and Supplier

Description:

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 introduces a system using 1-Octanol or Canola oil which are safe, readily available and inexpensive. This comprises a glass separation column, 1600mm long and 50mm diameter, packed with glass Raschig rings which provide a large surface area for the extraction process. Four process tanks are included, a feed tank and collection tank for the organic phase and a feed tank and collection tank for the aqueous phase.

Specification:

  • A laboratory liquid / liquid extraction column designed for use with 1-Octanol and Propionic acid
  • Column length 1.6m (1.2m working length), 50mm diameter, made from glass
  • Column packed with 15mm glass Rashig rings
  • 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
  • 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
  • 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
  • Fine adjustment of the lower phase interface to compensate for variation in specific gravity of the 1-Octanol
  • Instrumentation measures the inlet and outlet concentrations in the aqueous phase when using the recommended acid
  • Data logging as standard, software calculates acid concentration in the aqueous phase from which extraction efficiency can be determined (requires PC, not supplied)

Technical Specification:

  • 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
