Various extraction processes
Thread Content
The extraction processes include: single-stage extraction, multi-stage counter-current extraction, multi-stage counter-current extraction with reflux, multi-stage counter-current extraction using two solvents, and continuous counter-current extraction. Could anyone tell me how it is applied in industry?
In my industry, only single-stage extraction is used, with reaction vessels that include trial screenings
I usually work on laboratory extraction; I haven’t done much else of that kind
The most commonly used devices in industry are extraction towers and reaction vessels; extraction towers are used for continuous extraction, while reaction vessels are used for batch extraction
Multi-stage series counter-current extraction is widely used in industry, for example in the rare earth industry and pharmaceuticals
Extracting nickel using extraction during the production of spheroidized nickel
Liquid-liquid extraction is widely used in the pharmaceutical industry and for the separation of hydrocarbon products; we use single-stage extraction towers to separate C5 compounds
The metallurgical industry generally uses double counter-current extraction```
