摘要： 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.

摘要翻译： 产生一种或多种二甲苯异构体的芳族化合物通过复合物内的热交换提供了大量的节能能量的机会。 一个以前未被认识的机会是通过提供在不同压力下操作的两个平行蒸馏塔来分离C8芳族化合物与C9 +芳族化合物。 平行柱提供了额外的机会，通过相关的二甲苯回收设备中的热交换来节省复合物内的能量。

摘要： Processes and apparatus are provided that provide high yields of xylenes per unit of aromatic-containing feed while enabling a high purity benzene co-product to be obtained without the need for an extraction or distillation to remove C6 naphthenes. The processes of this invention include a transalkylation section and a disproportionation section in the benzene and toluene-containing feed is directly provided to the transalkylation section and in which a benzene recycle loop in the transalkylation section isolates the disproportionation section from C6 naphthenes.
