SS3G: An Integrated Risk Analysis Program Using Engineering Principles for Building Damage
(Mary Kay O'Connor Process Safety Center, 2001)
We announce the development, with the support of an industrial consortium, of an extensive new integrated modeling system named SS3G (Safe-Site 3rd Generation). This system is the first such risk analysis program to provide ...
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 ...
Explosion Risk Assessment, How the Results Vary With the Approach Chosen
(Mary Kay O'Connor Process Safety Center, 2001)
Within explosion risk assessment there is a range of methods being applied. Various kinds of guidelines and empirical models, where a lot of subjective assumptions will have to be done, are still widely used onshore. For ...
Role of Community Advisory Panels in the Aftermath of Critical Incidents in the Chemical Processing Industry
(Mary Kay O'Connor Process Safety Center, 2001)
Since the advent of "Responsible Care" initiatives, Community Advisory Panels ("CAP") have played an important role in ensuring community involvement in the safe operation of chemical facilities. Little consideration has ...
Issues in Fault Diagnosis and Isolation
(Mary Kay O'Connor Process Safety Center, 2001)
In the chemical and other related industries, there has been an impetus to produce higher quality products, to reduce rejection rates, limit down time, and to satisfy increasingly stringent safety and environment regulations. ...
Modeling Aerosol Rainout
(Mary Kay O'Connor Process Safety Center, 2001)
The AIChE Center for Chemical Process Safety has coordinated research efforts aimed at characterizing and predicting the behavior of aerosols during accidental releases. Field tests designed to be used for validation of a ...
Quantitative Risk Analysis - A Realistic Approach to Relief Header and Flare System Design
(Mary Kay O'Connor Process Safety Center, 2001)
As process industry facilities increase production capacity and add processing units, existing relief headers and flare systems are frequently found to no longer meet the same conservative design criteria used for the ...
Integration of a Reactive Chemicals Program into the Process Hazard Analysis Process at The Dow Chemical Company
(Mary Kay O'Connor Process Safety Center, 2001)
Dow's Reactive Chemicals Program has been in place since 1967 and has been utilized globally by Dow to reduce the hazards associated with reactive chemical scenarios. With the evolution to a broader Process Hazard review, ...
Risk Based Inspection Case Studies" Does RBI improve plant safety?
(Mary Kay O'Connor Process Safety Center, 2001)
In order for a facility to extend the operating lifetime of pressure vessels and piping, safely and cost effectively, it is necessary to implement the latest inspection and maintenance strategies. Risk Based Inspection ...
