摘　　要：利用ASPEN PLUS化工流程模拟软件对苯加氢系统的二甲苯塔进行了模拟计算,获得了和设计值一致的数据。通过对二甲苯塔的进料状态、回流比和侧线采出量等问题的分析,提出了最优的操作方案,达到了提高塔的最大处理能力和增效降耗的目标。The distillation tower in the benzenol hydrorefining system was simulated by the ASPEN PLUS software and the simulation results were consistent with the design data. According to the calculation, the feed condition, reflux ratio and side flow of the xylene tower were analyzed and an optimized operation scheme suggested. The results show that the new project improves the maximum processing capacity and can increase output and decrease consumption.
