In the production of fine chemicals and pharmaceutical intermediates, 3-mercaptopropionic acid (3-MPA), an important sulfur-containing compound, is widely applied in drug synthesis, polymer modification, and other fields. However, its production process is complex and prone to multiple side reactions, resulting…

In cutting-edge fields such as semiconductors, new energy batteries, and aerospace, high-purity metals (such as cobalt, nickel, lithium, etc) have become indispensable “industrial blood.” However, efficiently and sustainably extracting and refining these “metal treasures” from complex waste liquids, low-grade ores,…

Success Story: Turning Wastewater into High-Purity DMF One chemical plant successfully upgraded its wastewater treatment process by adopting Tiei Extraction’s CWL-M centrifugal extractor. The wastewater, initially containing 16% DMF, was processed at room temperature with a daily capacity of 15…

In chemical production, acid washing, alkali washing, and water washing are common process steps, mainly used to remove inorganic salts and other impurities from organic substances. Traditional processes mostly rely on batch reactors, where separation is achieved through steps such…

In the field of hydrometallurgy, efficient and economical recovery of copper from PLS produced by heap leaching or in situ leaching has always been the key to improving the competitiveness of enterprises. While traditional mixer settler is widely used, their…

In the production of pharmaceutical and pesticide intermediates, pyridine base compounds are hailed as the “chip” of the three major heterocycles, and their manufacturing process directly impacts the green development of the entire industry chain. However, in the mainstream synthetic…
