Description
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:
- Theoretical study of solid-liquid extraction processes:
• Percolation.
• Extraction in suspension.
• Extraction by immersion.
• Vapour extraction. - Study factors influencing extraction:
• Nature of solute and solvent.
• Temperature and stirring of medium. - 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.
