摘　　要：重芳烃分离装置是为分离重整装置二甲苯塔塔底产出的碳九芳烃而设计的。为弥补原料不足,加工组分和馏程变化较大的、以碳九、碳十芳烃为主要成分的重芳烃宽馏分进口原料,经方案选择、工艺模拟计算及流程改进,成功地生产了偏三甲苯与富集均三甲苯工业产品。The separation installation is designed to separate C9 aromatics from the bottom of the dimethyl benzene tower in reforming plant. The selection for design scheme, the simulation and calculation for process, and the modification for flow process were conducted to remedy the insufficiency of materials, the imported heavy aromatics with C9 and C10 aromatics as chief components, containing different components and wide distillation range, were used as materials, having produced successfully eligible 1,2,4- and 1,3,5-trimethylbenzene in industry.
