PIGNAT Solid Liquid Extraction – ESS2000


SKU: ESS2000 Category: Tags: , ,


Study two solid-liquid extraction methods:  extraction in a fixed bed and in suspension

The Solid-liquid extraction is a unit operation which entails extracting a compound (solute) from a solid phase using a liquid (solvent), producing a solution enriched in solute (extract) and a depleted solid phase (residue).

Proposed experiments:

  1. Theoretical study of solid-liquid extraction processes:
    • Percolation.
    • Extraction in suspension.
    • Extraction by immersion.
    • Vapour extraction.
  2. Study factors influencing extraction:
    • Nature of solute and solvent.
    • Temperature and stirring of medium.
  3. Experimental study:
    • Extraction of chlorophyll in aqueous medium.
    • Extraction of lavender by washing out with steam.
    • Percolation of coffee.
    • Extraction of plant extract with an organic solvent.
