In the production of hydrometallurgy, when extracting rare metals, centrifugal extractor can be used for non-equilibrium extraction. The two-phase contact time in the centrifugal extractor is very short (a few seconds), so that one element with a fast mass transfer…

In the production process of fine chemicals such as pharmaceutical API and pesticide intermediates, extraction and separation are the core links that determine product purity and production efficiency. Traditional extraction processes often face problems such as low efficiency, high energy…

Trialkylacetic acid, also known as tertiary carbonic acid or neoacid, is a type of branched monobasic saturated carboxylic acid and an important branch of industrial fatty acids. Tertiary carbonates have excellent hydrolysis resistance, and also have high heat resistance, weather…

In the production process of enterprises, after repeated use of water washing and other processes, the water will contain oil. If you want to recycle the water for continued use, you need to separate the oil from the water to…

Salicylic acid is a fat-soluble organic acid, also called o-hydroxybenzoic acid. In the process of producing salicylic acid, a large amount of phenolic wastewater will be produced at the same time. These phenolic wastewaters are very harmful, not only polluting…

The main method for extracting zinc from flue ash is solvent extraction. The specific process flow is: leaching-purification-extraction-stripping-electrolysis. In the leaching stage, acid leaching is generally selected, mainly using sulfuric acid as the leaching agent. After leaching, the purification stage…
