Zhengzhou Tiei Extraction specializes in liquid–liquid separation equipment and process engineering. For industrial DMF (Dimethylformamide) wastewater treatment and solvent recovery, Tiei Extraction provides a fully integrated centrifugal extraction process solution covering capacities from 1 to 60 m³/h, helping chemical, pharmaceutical, and synthetic materials enterprises achieve efficient solvent recovery and reduced operating costs.
Innovative Process: Integrated Extraction–Distillation System
This solution adopts an advanced route combining solvent extraction with distillation purification. A specially formulated extractant efficiently captures DMF molecules within a centrifugal force field, forming an enriched organic phase, which is then refined through low-temperature distillation to obtain regenerated DMF with purity above 99.5%. This technical approach breaks through the limitations of the traditional single distillation mode, achieving a comprehensive upgrade in terms of processing efficiency, energy consumption control, and equipment adaptability.
Complete Equipment Configuration: Precisely Matching Production Requirements
To meet the needs of enterprises of different production scales, Tiei Extraction provides modular system configurations:
CWL-M Centrifugal Extractor Small & Medium Systems (1–10 m³/h): Compact units suitable for pilot-scale or small-capacity wastewater treatment.
CWL-M Centrifugal Extractor Large Systems (11–60 m³/h): Designed for continuous industrial-scale production.
Each CWL-M centrifugal extractor system offers the following core advantages
1.Ultra-low energy consumption: Overall energy use reduced by 50–70% compared with traditional distillation
2.High recovery efficiency: DMF recovery rate stabilized at 98.5–99.8%
3.Intelligent control system: Fully automated operation with real-time monitoring of process parameters
4.Excellent corrosion resistance: Fluoropolymer-lined flow channels suitable for complex wastewater compositions
5.Compact layout: Footprint reduced to about 40% of conventional systems
Full Lifecycle Technical Support
Tiei Extraction provides comprehensive support from process validation to long-term operation:
Process Design Stage: Wastewater composition analysis, Process route optimization, Economic feasibility evaluation
Engineering Implementation Stage: Customized equipment manufacturing, Automation integration, Installation and commissioning
Operation & Maintenance Stage: Operator training, Remote monitoring services, Periodic optimization and upgrades
With increasingly stringent environmental regulations and the growing value of solvent resources, efficient DMF recovery has become a key factor in enhancing enterprise competitiveness. Tiei Extraction will continue advancing centrifugal extraction technology to deliver more efficient, economical, and sustainable solutions for industrial solvent recovery.
