Sulfolane, a highly effective solvent, is widely used in the chemical and pharmaceutical industries. However, its wastewater discharge has become a major environmental challenge for these companies. Traditional recovery methods are inefficient, energy-intensive, and result in significant solvent loss, leading to the waste of valuable sulfolane resources. Zhengzhou Tiei Extraction Technology, leveraging its leading centrifugal extraction technology, provides an efficient, cost-effective, and green solution for sulfolane wastewater recovery.
Centrifugal Extraction: A Revolutionary Process for Sulfolane Recovery
Zhengzhou Tiei Extraction Centrifugal Extractor adopts a unique multi-stage countercurrent centrifugal extraction process to efficiently separate and enrich sulfolane in wastewater:
1.Precisely match the extraction agent: Based on the physical and chemical properties of sulfolane, highly selective and low water-soluble extraction agents are preferred to ensure efficient capture of target substances.
2.High-speed centrifugal mixing and separation: The wastewater and the extraction agent are instantly and fully mixed in the high-speed rotating drum, and then quickly separated under the action of strong centrifugal force, greatly shortening the mass transfer time.
3.Multi-stage countercurrent extraction: The equipment adopts a compact countercurrent design to achieve multi-stage continuous extraction. The wastewater and extraction agent flow in countercurrent, and each stage pushes sulfolane into the extraction phase for enrichment, significantly improving recovery.
4.Efficient stripping and regeneration: The extraction phase loaded with sulfolane enters the stripping section, where sulfolane is released under suitable conditions, and the extraction agent is recycled to reduce costs.
5.Solvent distillation and purification: The sulfolane solution obtained by stripping is purified by distillation to obtain a high-purity product that can be directly reused in the production process.
Advantages of Zhengzhou Tiei Extraction CWL-M Centrifugal Extractor
1.High recovery rate and high purity: The multi-stage countercurrent design can stably achieve a sulfolane recovery rate of more than 95%. The product purity meets the reuse requirements, turning waste into treasure.
2.High processing efficiency and small footprint: High-speed centrifugation achieves mixing and separation in seconds, with large equipment throughput and short process, occupying only 1/5-1/3 of the floor space of traditional equipment.
3.Low operating cost and low energy consumption: Closed operation and high recycling rate of extraction agent; compared with distillation method, energy consumption can be reduced by 30%-50%.
4.Green, environmentally friendly, safe and reliable: Closed operation reduces volatilization loss and secondary pollution; the equipment has a high degree of automation and operates stably and safely.
Zhengzhou Tiei Extraction Company's centrifugal extraction process for recovering sulfolane from wastewater is an advanced, efficient, rapid, compact, highly automated, and environmentally friendly process. Its core advantage lies in the use of powerful centrifugal force to achieve ultra-fast separation, greatly improving stage efficiency and recovery rate, while reducing solvent consumption and floor space. This technology can effectively solve the problem of sulfolane wastewater treatment and achieve the dual goals of resource recovery and environmental protection. It has broad application prospects in industries such as petrochemicals, natural gas purification, and pharmaceuticals that produce sulfolane-containing wastewater.
