In liquid–liquid extraction processes, the operational stability and separation efficiency of centrifugal extractor are critical, and phase entrainment is a core issue that directly affects product quality and yield. The operating principle of a centrifugal extractor mainly consists of two…
As a key intermediate for a wide range of acid, direct, and reactive dyes used in wool and cotton textile dyeing, H-acid generates wastewater during the production of its crystallization mother liquor that is characterized by high color, strong acidity,…
In the hot-dip galvanizing and metal processing industries, the treatment and resource recovery of zinc-containing pickling waste liquor is an important issue that requires balancing environmental protection with economic benefits. Conventional methods such as neutralization–precipitation and evaporation–concentration generally suffer from…
In the process of producing high-purity lithium carbonate from lithium-containing brines, the removal of boron is a critical step. Due to the high solubility of boric acid and borate species in brine, boron is difficult to effectively remove by conventional…
In fine chemical production, removing DMF from the dichloromethane system containing the target product is a crucial purification step. Traditional batch-type reactor extraction methods are not only inefficient and labor-intensive but also fail to meet the requirements of modern production…
The CWL-M series centrifugal extractor manufactured by Zhengzhou Tiei Extraction has a good reputation in the industry. Their advantages are mainly reflected in the following aspects, which have led to their widespread application in chemical, pharmaceutical, environmental protection, and hydrometallurgy…
