Heat transfer modeling of high expansion foam application for vapor risk mitigation of Liquefied Natural Gas (LNG) spills
(Mary Kay O'Connor Process Safety Center, 2018)
The consumption of natural gas is expected to increase significantly over the next few decades due to much less carbon dioxide emission per unit of energy, when compared to other sources like oil or coal. This has also ...
Buckets to Disaster: What to Avoid in Making Critical Decisions
(Mary Kay O'Connor Process Safety Center, 2017)
This paper offers an approach to the development of techniques and tools to teach risk-based decision analysis and complex decision analysis to minimize the disastrous outcomes of critical decisions taking in the worlds ...
A Hazard Identification Framework of Complex Systems
(Mary Kay O'Connor Process Safety Center, 2018)
A chemical process facility is a highly complex system. The interactions among a small group of the functions, such as process, equipment, human, organizational functions, could split, merge or couple leading to a complex ...
Review: Overview of flame retardant additives, mechanism of flame retardancy and characterization techniques for polymer nanocomposites
(Mary Kay O'Connor Process Safety Center, 2017)
Fire retardancy of plastics is becoming increasingly important due to the widespread application of plastics in daily life and the subsequent fire hazard associated with it. A wide variety of flame retardant additives have ...
Modelling Ice and Wax Formation in a Pipeline in the Arctic Environment
(Mary Kay O'Connor Process Safety Center, 2019)
In the Arctic environment, fluid temperature in pipeline can drop below the freezing point of water, which causes wax and ice to form on pipeline surface. Solid formation on pipeline surface can lead to flow assurance and ...
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 ...
Spontaneous Combustible Substances: a Database Update
(Mary Kay O'Connor Process Safety Center, 1999)
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 ...
System Dynamical Simulation of Risk Perception for Enterprise Decision-Maker in Communication of Chemical Incident Risks
(Mary Kay O'Connor Process Safety Center, 2016)
System Dynamical Simulation of Risk Perception for Enterprise Decision-Maker in Communication of Chemical Incident Risks
Multi-Objective Stochastic Optimization for Preventive Maintenance Planning
(Mary Kay O'Connor Process Safety Center, 2018)
Maintenance is an essential part of mechanical integrity programs and aims to prevent the occurrence of process safety incidents and costly unplanned shutdowns. Maintenance can increase the reliability of equipment in ...
