✦ Synopsis

A new methodology, fault-dynamic modelling, has been developed for analysis of potentially hazardous situations in the process industries. Traditional fault-tree analysis is used to determine the combinations of component failures that can lead to a particular process upset condition. Realistic dynamic modelling is then used to calculate the time available for corrective action once the upset has started. The method is applied to e phthalic anhydride reactor. The results of the analysis identify three process upsets that can lead to catastrophic failure in 2-5 min if left uncorrected. Other process upsets lead to safe conditions.

## Abstract In this paper, we present a method for detecting faults that can appear in some parts of a chemical plant. This method is based on statistical information generated by the Extended Kalman Filter (EKF) technique and is designed to reveal any drift from the normal behavior of the process.

## Abstract Although there are several kinetic models for the production of phthalic anhydride from the partial oxidation of __o__‐xylene, only few studies have compared the effect of the kinetic model on the prediction of the hot‐spot temperature. In this work, the predicted temperature profile fo
