Abstract
The invention relates to a process () for deriving polymerizable aromatic compounds having nine carbon atoms (S) in which a component mixture (B) is formed at least partially by steam cracking, in which the component mixture (B) is subjected to a workup () comprising a gasoline removal () and thereafter is a compression () and a fractionation (), and wherein one or more pyrolysis gasoline fractions (H, L) is or are formed in the gasoline removal () and/or the compression (). The invention provides that a separation feed is formed which comprises predominantly exclusively pyrolysis gasoline from the or at least one of the pyrolysis gasoline fractions (H, L) and that the separation feed is subjected to a separation (), wherein in the separation () at least one fraction (P) enriched in aromatic compounds having nine carbon atoms compared to the separation feed is formed. A corresponding plant likewise forms part of the subject matter of the invention.
