SORBION

How It Works

• Selective adsorption - functionalised resins selectively bind impurities such as heavy metals based on chemical affinity.
• Targeted impurity removal - removes trace metals like Pd, Pt, Cu, Hg, Pb, and others from reaction mass and effluents.
• Column or batch operation - operates in fixed-bed (continuous) or slurry (batch) modes depending on process needs.
• Process optimization - resin selection is based on impurity type, followed by pilot trials and scale-up.
• Counter-current operation - adsorption columns are designed based on flow rates and ppm-level impurity concentrations.

Key Features

• High selectivity for low ppm impurities
• Enables recovery of precious and valuable metals
• Economical operation with reduced OPEX
• Supports catalyst recycling and reuse
• Stable chemical and physical properties
• Non-swelling resin structure
• Easy handling with pellet form
• Flexible operation (batch or continuous)
