粗苯蒸馏操作制度的分析与优化

Analysis and optimization for operating system of crude benzol distillation

运用模拟仿真计算方法对粗苯蒸馏单元的操作温度、蒸汽耗量、回流比以及产品质量等参数进行分析,找到最佳的操作参数。通过对操作制度的细微调整,在保证粗苯产品合格的同时,可以降低循环洗油的萘含量,避免萘在洗苯塔内析出,还可以降低净煤气的萘含量,为焦炉煤气的深加工打好基础。

We obtained optimized operating parameters by analyzing the datum such as operating temperature,steam consumption,reflux ratio and products quality,etc.by numerical simulation.The fine tuning of the operating system can not only guarantee qualified crude benzol products,but also reduce naphthalene content in circulating wash oil so as to prevent the naphthalene from separating out inside benzol scrubber and decrease the naphthalene content in the purified gas,which will lay a solid foundation for further treatment of the coke oven gas.
