The main forms of titanium in the earth’s crust are titanium dioxide and titanate, and usually coexist with fe, ca, mg, si, al, mn and rare earth elements. According to statistics, there are more than 140 kinds of titanium minerals,…
In many fields such as chemistry, medicine, and food, the processing technology of extraction liquids plays an important role. In actual production, we often encounter situations where we need to perform multi-stage extraction on the extraction liquids. This article will…
Liquid liquid extraction/solvent extraction is a technique for separating substances based on the different solubility or partition coefficients of substances in two immiscible or slightly soluble solvents. Here are some key information about solvent extraction: Liquid liquid extraction is an…
Current Status of NMP Wastewater Treatment NMP can be miscible with water in any ratio, has high boiling point, flash point and strong solubility, so it is not easy to separate and recover directly from NMP aqueous solution. Its recovery…
In the field of organic synthesis, water washing, as a basic and crucial process, runs through the production process of many products. Its important value lies in effectively removing the residual acid, alkali, salt and other water-soluble impurities in the…
The treatment of naphthenic acid wastewater is relatively complicated due to its high COD concentration and difficulty in biodegradation. As an effective liquid-liquid extraction and separation equipment, the centrifugal extractor plays an important role in the treatment of naphthenic acid…
In the chemical industry, dimethylformamide (DMF) is an indispensable solvent and is widely used in the production of medicines, pesticides, dyes, etc. However, with its large-scale use, the problem of DMF wastewater treatment has become increasingly prominent, posing a severe…
