Quality differences among aromatic oil types
Thread Content
What is the difference in quality between the fractionated aromatics and the extracted aromatics? Thank you
The aromatic hydrocarbons obtained through extraction have a higher purity; after extraction, distillation is required for further separation.
The aromatic extraction process is a method for separating the aromatic components from the non-aromatic components in the reformate oil; the aromatic compounds obtained through this process are a mixture that includes triphenyls and small amounts of heavy aromatics. This process utilizes the principle of extraction separation. The aromatic distillation process is a method in which an aromatic mixture is separated into individual components through distillation, with the aim of obtaining pure aromatic compounds. This process uses the difference in boiling points for fractional separation. These are two completely different separation process operations.
