ABSTRACT:
An improved aromatics extraction process is disclosed. Key feature of the present invention is use of the fractionator in the hydrodealkylation unit or other unit with a benzene fraction to fractionate not only hydrodealkylated benzene but also extracted benzene. The extracted benzene is used as "pseudo" reflux in the hydrodealkylation unit fractionator, thereby reducing the reflux requirement. The conventional re-run fractionator for clay treated benzene extract is eliminated, since polymerized olefins in this extract are removed as a bottoms fraction from the hydrodealkylation fractionator.
