    • Enabling a transalkylation process to handle both C10 alkylaromatics and unextracted toluene permits the following improvements to be realized. No longer extracting toluene allows a reformate-splitter column to be eliminated. The extraction unit can be moved to the overhead of a benzene column. No longer requiring a rigorous split between C9 and C10 alkylaromatics allows a heavy aromatics column to be eliminated. Such an enabled transalkylation process requires stabilization of a transalkylation catalyst through the introduction of a metal function. A further enhancement to the flow scheme is accomplished through the elimination of clay treaters in favor of selective olefin saturation at the exits of a reforming unit and an isomerization unit. These improvements result in an aromatics complex with savings on inside battery limits curve costs and an improvement on the return on investment in such a complex.
    • 实施烷基转移方法来处理C10烷基芳族化合物和未萃取的甲苯允许实现以下改进。 不再提取甲苯可以消除重整分离柱。 提取单元可以移动到苯塔的塔顶。 不再需要C9和C10烷基芳族化合物之间的严格拆分,可以消除重芳烃柱。 这种使能的烷基转移方法需要通过引入金属官能团来稳定烷基转移催化剂。 通过消除粘土处理剂有利于重整单元和异构化单元的出口处的选择性烯烃饱和来实现流程图的进一步改进。 这些改进导致了芳烃复合物,节省了内部电池限制曲线成本,并改善了这种复杂的投资回报。
