粗苯加氢工艺改进和焦化苯生产试剂苯新工艺

Amelioration of Crude Benzene Hydrogenation Process and the New Process of Utilizing Coking Benzene to Produce Reagent Benzene

分析了原粗苯加氢工艺与装置存在的问题,通过在加氢单元前增加预处理装置,完善了粗苯加氢工艺,提高了装置的产能,生产的轻苯、重苯都达到了设计要求;介绍了利用焦化苯生产试剂苯新工艺实现工业化的情况,产品符合分析纯二级试剂标准,取得了较好的经济和社会效益。

The problems existed in the old process of crude benzene hydrogenation and equipment were analyzed. The process was improved and the capacity was enhanced through adding a pretreatment apparatus before the hydrogenation unit. The quality of both light benzene and heavy benzene was up to the design requirement. The commercialized production of reagent benzene （analysis class Ⅱ） from coke benzene was introduced. The economic and social benefit is prominent.
