In industries such as chemicals, pharmaceuticals, and food processing, ethyl acetate is an important organic solvent, and its effective separation from water has long been a critical technical step. Although traditional separation methods such as distillation are widely used, challenges…

In vanadium extraction processes, whether using the traditional sodium roasting-acid leaching method or the novel salt-free roasting-acid leaching method, the final step involves an extraction process to achieve efficient separation and purification of vanadium. The CWL-M centrifugal extractor, based on…

In the development of hydrometallurgical processes, scaling up from laboratory research to industrial production is a critical step that often determines the success or failure of a project. The CWX-J Series laboratory mixer settler, independently developed by Zhengzhou Tiei Extraction,…

In many industrial fields such as chemical processing, pharmaceuticals, environmental protection, and hydrometallurgy, liquid liquid extraction is a core technology for separation and purification. Its efficiency and economic performance directly influence the overall competitiveness of production lines. Traditional equipment, such…

In the production workshop of a fine chemical enterprise, a mature process is operating steadily. A complete sequence—two stages citric acid washes, two stages alkaline washes, and two stages water washes—is repeated cycle after cycle in a 30-cubic-meter reactor. Although…

In various industrial fields such as chemicals, pharmaceuticals, and dyeing, dimethylformamide (DMF) is widely used as an important organic solvent. However, high-concentration DMF wastewater (with concentrations of 1%–20%) generated during production presents significant treatment challenges due to its complex composition,…
