安阳钢铁集团有限责任公司焦炉煤气回收苯有两个系统,均采用洗油洗苯和堂式炉加热脱苯工艺,两系统洗苯塔均采用填料塔,但二系统洗苯塔后煤气含苯明显高于一系统洗苯塔后含苯即二系统洗苯塔吸收效率不佳,进行原因分析,验证,对策实施,提高苯的回收率。
Anyang iron and steel group company limited has two systems to recovery benzene from coke oven gas,and both of two systems are packed column,but comparing the first system,the second system was of lower absorbing efficiency in benzol washing tower because gas washed by the second system contained higher benole.Then the article analysed the reason,made verification,and implemented strategies to increase the recovery rate of benzene.
