Product Purification
Remove Impurities to achieve Regulatory and Performance Requirements with no Product loss.
Pharmaceutical & Bio-tech - metals and organic impurities to < 1ppm or lower; No product loss, No added impurities
Precious Metal Recovery - recover a very high % of the metal value;
Electronic Chemicals - Precious Metals and Li, Na, K. Mg, Ca, Fe, Cu etc to <1 ppm or lower
Performance and Fine Chemicals - cost-effective removal of metals and organic impurities
Precious Metal Recovery
Recovery of Precious Metal & Gold from Product, Process and Waste streams
Recovery of Precious Metal & Gold from product, process and waste streams
Very high metal recovery and selective for the target metal
Cost-effective and simple processes to implement with low environmental impact; implementation with significant commercial, operational and environmental benefits and on site operation.
Reactions
Hydroformylation - Rhodium - For production of acids, aldehydes and alcohols
Cost effective processes, very high metal recovered, very low residual metal content
Hydrosilylation - Platinum - silanes and silicones - >95% Platinum recovery achievable
C-C (Suzuki) & C-N (Buchwald-Hartwig) coupling - Palladium & Rhodium >99% metal recovered
Hydrogenations - Pd, Pt, Ru, Rh recovered from product, process, waste streams & catalyst washing
Oxidations, Rearrangements, Protection/De-protection Pd and Pt >98% recovery
Process, Coating and Washing Streams

separation of Copper from Gold streams
Environmental Scavenger-Solutions
Stricter enforcement and lower regulatory residual levels require more effective Scavengers.
Si-Novation Smart Novel Technology meets these and future regulatory lower levels.
Scavenger Solutions are available for the metals highlighted in blue in the Periodic Table.
Notable - Scavengers for Ni, Cu, Cr and Fe achieving <0.1 ppm
