摘要: 分析了脱苯塔整体操作条件,研究了操作参数对粗苯 Cl - 含量的影响。根据实际生产情况,为保证粗苯 Cl - 含量达标,应将塔顶温度控制在 80 ℃左右,塔顶压力在 -30 kPa 左右,塔底压力在 -20 kPa 左右。研究可知, 蒸汽添加量、回流量与粗苯 Cl - 含量呈反比关系;贫富油 Cl - 含量与粗苯 Cl - 含量的整体变化趋势相同。

Abstract: This paper analyzed the overall operating conditions of benzol stripper and studied the effect of operating parameters on Cl- content in crude benzol.According to the actual situation and in order to ensure that the Cl- content in crude benzene reaches the standard,the stripper top temperature should be controlled at about 80 ℃,the stripper top pressure at about -30 kPa,and the bottom pressure at about -20 kPa.The research shows that the amount of steam added and the reflux flow rate are inversely proportional to the Cl- content in crude benzol.The overall change trend of Cl- content of lean and rich oil is the same as that of crude benzol.

Key words: Crude benzol distillation, Benzol Stripper, Operating parameters, Cl- content
