In the field of fine chemicals and pharmaceuticals, 2-Methylfuran is an important organic solvent and intermediate, and its production process often faces the problem of efficient separation from the aqueous phase. The traditional static stratification method has problems such as long time consumption, low efficiency, and solvent residue. The CWL-M series centrifugal extractor independently developed by Tiei Extraction provides a solution to this industry pain point with its advanced solvent extraction technology and equipment innovation.
2-Methylfuran and Water Separation
2-Methylfuran is slightly soluble in water (about 1.3% solubility at 25°C), and often forms an emulsified or microemulsified mixture after the synthesis reaction. Traditional gravity sedimentation takes several hours and is prone to entrainment losses. In addition, its low boiling point (63-65°C) makes the distillation method energy-intensive and poses safety risks. Although the solvent extraction method can achieve directional separation, the conventional extraction column equipment is large in size and low in efficiency, making it difficult to meet the needs of modern continuous production.
Advantages of Centrifugal Extractor
Tiei Extraction CWL-M series centrifugal extractor adopts an integrated design of multi-stage countercurrent extraction + high-speed centrifugal separation, optimize the process according to the characteristics of the 2-methylfuran-water system, and achieve three core breakthroughs:
- Ultra-short residence time
Through the 4000-6000rpm high-speed centrifugal force field, the mixing-mass transfer-phase separation process is compressed to seconds, avoiding the risk of emulsification, especially suitable for heat-sensitive material processing. - Stage efficiency > 95%
The special drum structure and composite filler design increase the contact area of the two phases by more than 3 times, and the single-stage extraction efficiency far exceeds that of traditional equipment, reducing the number of extraction stages and solvent usage. - Intelligent control
Integrated online pH and flow monitoring system, automatically adjust the ratio of extractant (such as n-hexane, cyclohexane) to feed liquid, and ensure separation purity (2-methylfuran recovery rate ≥ 99.2%).
Centrifugal Extractor Application Cases
A pharmaceutical intermediate company uses CWL-M centrifugal extractor to treat a wastewater system containing 15% 2-methylfuran. Operation data comparison:
Processing capacity: 8m³/h (220% higher than the original extraction column)
Solvent loss: <0.5kg/ton product (reduced by 67%)
Effluent index: 2-MF content ≤50ppm (meets national emission standards)
The CWL-M centrifugal extractor is characterized by high efficiency, energy saving and safety. For difficult-to-separate systems such as 2-methylfuran, Tiei Extraction provides a full-process solution from laboratory testing to 10,000-ton production lines, helping enterprises achieve quality improvement, efficiency enhancement and green transformation.
