摘要
为了扩大某100 kt/a环己酮装置的生产能力,对现有氧化反应系统进行改造。分析了氧化反应装置提产的原理,介绍了采用冷模实验与CFD数值模拟研究方法开发的气体再分布器的结构,以及再分布反应器替代原有分布器后的应用效果。生产运行结果表明:该反应装置每年可增产35 kt/a环己酮,且降低了吨酮制造成本,值得推广。
In order to enlarge the production capacity of a 100 kt/a cyclohexanone unit,optimization revamp is carried out for the existing oxidation reaction system.The principle of production improvement of oxidation reactor is analyzed,and the structure of gas redistributor developed by cold model experiment and CFD numerical simulation is introduced,as well as the application effect of redistributor replacing the original distributor.The production and operation results show that the reactor unit can increase 35 kt/a cyclohexanone production per year and reduce the production cost of per ton ketone,which is worth promotion.
