Hypergravity Distillation System for DMF & DMSO Waste Solvent Recovery

This column focuses on high-salt DMF & DMSO waste mother liquor recovery solutions based on hypergravity distillation technology. We will break down core technical principles, complete system configuration, practical process parameters, energy consumption data, and comparison advantages against traditional packed distillation towers. If you’re engaged in peptide CDMO, API synthesis, fine chemical production and troubled by blocked towers, high operation costs and unstable solvent purity when recycling polar solvents, this series will bring you practical, low-carbon recycling technical references. Stay tuned for full technical proposals, real-site project photos and case data sharing.Industry professionals engaged in fine chemical, pharmaceutical peptide synthesis, polymer manufacturing often face the pain point of waste DMF/DMSO mother liquor treatment: high salt content easily blocks traditional distillation towers, large tower footprint, high packing replacement cost, low separation efficiency & unstable solvent purity.

Our CX650-IV Hypergravity Distillation Recovery Skid delivers a fully customized, low-carbon alternative to conventional packed distillation columns for DMF & DMSO solvent recycling.

Core Working Principle

As a new-generation high-efficiency rotating distillation unit that replaces traditional towers, it employs gas-liquid countercurrent atomization mass transfer within the rotor. The liquid undergoes repeated dispersion & aggregation to generate an ultra-large, continuously refreshed gas-liquid contact interface, drastically boosting separation efficiency under negative pressure (98~90kPa) at mild 40–120°C operating temperature.

Target Feedstock & Processing Index

Suitable for high-salt DMF/DMSO waste mother liquor with raw composition: 20% chloride-free inorganic salts + 40% water + 35% DMF/DMSO + 5% mixed light solvents (methanol, toluene, etc.)

Monthly capacity: 25 tons (CX650-IV model)

Final solvent purity: DMF / DMSO ≥99.5%

Pre-distillation pretreatment solves salt crystal blockage of distillation channels fundamentally
