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…

In the acrylic acid extraction process, traditional extraction and separation processes often face challenges such as low efficiency, high solvent consumption, and easy emulsification, which directly impact production profitability. Zhengzhou Tiei Extraction Technology’s CWL-M series centrifugal extractor, with their unique…

In the precision manufacturing process of active pharmaceutical ingredients (API), efficient extraction and separation of reaction mixtures are the core links that determine product purity, yield and cost. With the increasingly stringent global drug regulation and the deepening of the…

In the context of the increasing importance of resource recycling, vanadium, as an important strategic metal, plays a key role in the fields of steel, new energy, aerospace, etc. More than 90% of the world’s vanadium is used in the…

As global environmental regulations become increasingly stringent and demand for resource recycling increases, waste lubricating oil regeneration technology is facing major changes. N-methylpyrrolidone (NMP) has become a common solvent in waste lubricating oil refining processes due to its excellent solubility…

Using centrifugal extractor to extract and recover dimethylformamide (DMF) from wastewater is an advanced technology that is efficient, fast and suitable for continuous production. The core is to use centrifugal force to accelerate the mixed mass transfer and rapid separation…
