  • Energy conservation in heavy-hydrocarbon distillation
    Patent number: 8754281
    Abstract: An aromatics complex producing one or more xylene isomers offers a large number of opportunities to conserve energy by heat exchange within the complex. One previously unrecognized opportunity is through providing two parallel distillation columns operating at different pressures to separate C8 aromatics from C9+ aromatics. The parallel columns offer additional opportunities to conserve energy within the complex through heat exchange in associated xylene recovery facilities.
    Type: Grant
    Filed: August 25, 2010
    Date of Patent: June 17, 2014
    Assignee: UOP LLC
    Inventors: Gregory R. Werba, Jason T. Corradi, Zin X. Zhu, David W. Ablin, Saadet Ulas Acikgoz
