Adaptability of statistical process control tools to modifications in plant operation strategies
The influence of modifications in the operation strategy of a chemical plant on the output of statistical process control (SPC) tools developed for fault detection is examined. Particularly, the square prediction error (SPE) and the Hotelling T2 charts are analyzed for reported problems. The effect...

The influence of modifications in the operation strategy of a chemical plant on the output of statistical process control (SPC) tools developed for fault detection is examined. Particularly, the square prediction error (SPE) and the Hotelling T2 charts are analyzed for reported problems. The effect of training the tools either with an extended historic databank obtained under standard operation or including also non-conventional conditions is studied. The ability of the tools to provide a specific alarm is examined in both cases. In addition, the sensitivity for diagnosing a given problem by analyzing the contributions per variable to the SPE and the T2 is addressed. |
