Back propagation (BP) neural networks are applied for reactor fault diagnosis. Analyzed is the output prediction error between a neural network model and an independent dynamic process model, which serves as a residual for ...

This paper presents experimental measurements of the thermal decomposition reaction of 50 wt% hydroxylamine/water (HA) in an oxygen-free environment using an APTAC calorimeter. Overall kinetics, onset temperatures, heats ...

A database of spontaneous combustible substances is under development. Over 100 substances commonly found in the chemical processing industry have been included to date. Spontaneous combustion includes the several related ...

The evaluation of reactive hazards is necessary for the safe working of the chemical process industries. An integral aspect of reactive hazard testing is the screening of chemicals to focus experimental efforts on the more ...

Structured packing has been widely used because of large surface area that makes possible columns with high capacity and efficiency. The large surface area also contributes to fire hazards because of hydrocarbon deposits ...

This paper explores a novel approach for improving chemical safety in the United States by establishing National Process Safety Goals. Process safety initiatives in the recent years have given rise to significant increases ...

Fault tree analysis (FTA) has been used in the chemical process industry (CPI) for systematic safety and reliability analysis during the past decades. Once constructed, the fault tree can be of considerable value in ...
