Description

The Chromatography process:

• Feed components have different affinities for the solid phase (resin)è different velocities / retention times across the resin bed
• Slow components have high affinity for the resin: can enter inside the resin / make complex with the resin functional groups.
• Fast components have less affinity for the resin: cannot enter inside the resin / cannot make complex with the resin functional groups.
• Primary filtration to remove mycelium
• Membrane filtration to clarify broth
• Concentration
• Chromatography to separate citric e.g. acid from remaining non fermented sugars, and organic and mineral impurities
• Polishing by activated carbon and ion exchange
• Crystallization

Applications in Chemical Industries: 

• Recovery of metals in liquid phases (metal plating, washing bath, metal leaching)
• Separation of metals by ion exchange
• Separation of acid/acid salts by acid retardation (sulphuric, hydrochloric, phosphoric…)
• Recovery of dyes
• Catalysis on resin
• Recycling and drying of organic solvent
