摘要：An aromatics complex producing one or more xylene isomers offers a largenumber of opportunities to conserve energy by heat exchange within the complex. Onepreviously unrecognized opportunity is through providing two parallel distillationcolumns operating at different pressures to separate Caromatics from C+ aromatics. Theparallel columns offer additional opportunities to conserve energy within the complexthrough heat exchange in associated xylene recovery facilities.
