摘　　要：为进一步提升焦化粗苯精馏工艺所得产品的纯度,降低生产成本,在对当前焦化粗苯精馏工艺所面临实际问题分析的基础上,对间歇精馏工艺展开重点研究;通过搭建实验平台分别对回流比和溶剂加入速率对最终产品纯度的影响进行研究,并得出最佳的工艺参数。In order to further improve the purity of the products obtained from the coking crude benzene distillation process and reduce production costs,based on the analysis of the actual problems faced by the current coking crude benzene distillation process,key research has been conducted on the intermittent distillation process.By establishing an experimental platform,the effects of reflux ratio and solvent addition rate on the purity of the final product were studied,and the optimal process parameters were obtained.
