A Robust Sensor Fault Diagnosis System Using Neural Networks and a Dynamic Process Model
(Mary Kay O'Connor Process Safety Center, 2001)
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 ...
Effect of Air in the Thermal Decomposition of 50 wt.% Hydroxylamine/water
(Mary Kay O'Connor Process Safety Center, 2001)
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 ...
Computer-aided Fault Tree Synthesis for Quantitative Risk Assessments
(Mary Kay O'Connor Process Safety Center, 2001)
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 ...
