Aromatic extraction can separate aromatics with several carbon atoms
Thread Content
The aromatic extraction process can separate aromatics with different numbers of carbon atoms; is it only capable of separating toluene and mixed xylene? Can those aromatic compounds with more than 9 carbon atoms be separated? Please give me some advice!
Currently, conventional aromatic separation involves separating them into C9. Aromatics above C9 can be separated, with a fractional distillation column added later in the process.
C1~C5 are called raffinate oils. C6 benzene, C7 toluene, C8 xylene; those with atomic numbers higher than C9 are called heavy aromatics
Are there any industrial applications for aromatics with a grade of C9 or higher?
Aromatic extraction depends mainly on what the raw material being extracted is and what extractant is used; however, the C9 components can generally still be separated
Based on the order in which solvents dissolve different hydrocarbons, it can be determined that C9A can be separated; it seems to have certain applications as well as economic benefits. However, the energy consumption required for this process is high, so it is usually not done

It starts with reformation, followed by pentane removal; after that, octane is removed and the mixture enters the extraction stage, where the raffinate oil is separated. Subsequently, it goes through distillation, allowing for the separation of benzene, toluene, mixed dichlorobenzenes, o-dichlorobenzene, and C9 compounds
C9 can be isomerized to produce blending components for high-octane gasoline
