摘　　要：针对复杂多变的石化装置操作过程,给定了一种基于统计过程控制的装置操作质量评估分析方法,主要包括制程能力指数评估、直方图正态分布分析、控制图异常数据查找、组间异常过程诊断等,能够帮助工艺员或操作员准确找出操作质量差的参数,辅助分析操作过程中的异常原因,达到保障装置的稳定运行、产品质量以及防止安全事故发生的目的。In this paper, a method of operation quality analysis based on statistics process control is proposed for the complex process situations in petrochemical industries. There are four modules including process capability index, histogram normal distribution analy- sis, abnormal data searching and fauh diagnosis be- tween groups. This method will help operators identi- fy the poor variables accurately and find the reasons of abnormal situations immediately, ensuring the sta- ble plant operation anti product quality, as well as preventing the accidents from happening.
