六西格玛在提高粗苯收率和优化工艺参数中的实践与应用

Practice and Application of Six Sigma Methodology in Improving Crude Benzene Yield and Optimizing Process Parameter

文章重点介绍如何运用六西格玛的DMAIC方法对可能影响粗苯收率的工艺参数进行筛选分析,以确定关键工艺参数,再运用Minitab软件对关键工艺参数的历史数据进行回归分析,得出有实际指导意义的理论模型,最终通过响应优化器给出关键工艺参数的调整方法。此外,将传统意义的粗苯收率定义分解为洗苯效率和脱苯效率,使得研究更具有针对性,为研究粗苯产线效率提升提供了一种新思路,可供参考。

The paper focuses on how to use the DMAIC method of Six Sigma to screen and analyze process parameters that may affect the yield of crude benzene,in order to find out the key process parameters,and then use Minitab software to conduct regression analysis on the historical data of the key process parameters to obtain a theoretically meaningful model with practical guidance.Finally,the adjustment method for key process parameters is provided through the response optimizer in Minitab software.In addition,the traditional definition of crude benzene yield into benzene washing efficiency and benzene removal efficiency,making the research more targeted and providing a new approach for improving the efficiency of crude benzene production lines for reference.
