Achieving high purity in specialty chemicals and solvents often requires the targeted removal of both polar and non-polar impurities, a challenge addressed by Sulzer’s advanced Solvent Extraction & Separation solutions.
These technologies enable precise impurity removal while preserving valuable product qualities and improving overall process sustainability.
Sulzer’s flagship liquid-liquid extraction platform, OptimEXT™, combines high-performance Kühni™ agitated columns with integrated solvent recovery to provide outstanding removal efficiencies even in complex feedstocks.
The system is engineered to selectively remove polar impurities like acids and amines or non-polar contaminants such as aromatic hydrocarbons, ensuring cleaner, compliant products.
Key application areas include:
Purification of solvents like DMF, NMP, DMSO, and acetone
Extraction of aromatic impurities from specialty chemicals
Removal of trace organic acids and bases for pharmaceutical and fine chemical applications
Recovery of flavors, fragrances, and vitamins with minimal degradation
By maintaining low operating temperatures and leveraging optimized mass transfer, Sulzer’s solutions minimize energy consumption and reduce solvent usage compared to traditional methods. Extensive pilot testing and modular design support easy integration and scale-up.
