  • Energy-efficient process for para-xylene production
    Patent number: 7553998
    Abstract: This invention is drawn to a process for producing and recovering one or more high-purity xylene isomers from a feed stream having a substantial content of C9 and heavier hydrocarbons. The feed stream is processed to de-ethylate heavy aromatics, fractionated and passed to a circuit comprising C8-aromatic isomer recovery and isomerization to recover the high-purity xylene isomer with lowered energy costs.
    Type: Grant
    Filed: June 21, 2006
    Date of Patent: June 30, 2009
    Assignee: UOP LLC
