Safety-oriented Resilience Evaluation in Chemical Processes
(2012-02-14)
In the area of process safety, many efforts have focused on studying methods to prevent the transition of the state of the system from a normal state to an upset and/or catastrophic state, but many unexpected changes are ...
Dynamic Operational Risk Assessment with Bayesian Network
(2012-10-19)
Oil/gas and petrochemical plants are complicated and dynamic in nature. Dynamic characteristics include ageing of equipment/components, season changes, stochastic processes, operator response times, inspection and testing ...
Study of the Effects of Obstacles in Liquefied Natural Gas (LNG) Vapor Dispersion using CFD Modeling
(2012-10-19)
The evaluation of the potential hazards related with the operation of an LNG terminal includes possible release scenarios with the consequent flammable vapor dispersion within the facility; therefore, it is important to ...
Study of the Influence of the Main Input Parameters on Toxic Consequence Calculation for a Formaldehyde Release
(2015-07-29)
Formaldehyde is widely used in the chemical industries as a raw material for resins, plastics, fertilizers, and polymers as a solvent, and a preservative. Due to its high reactivity, and acute toxicity, determining the ...
Modeling of LNG Pool Spreading and Vaporization
(2012-11-20)
In this work, a source term model for estimating the rate of spreading and vaporization of LNG on land and sea is introduced. The model takes into account the composition changes of the boiling mixture, the varying ...
Facility Siting and Layout Optimization for Risk Reduction of Offshore Operations
(2015-07-17)
An MINLP optimization model has been created that optimizes the layout of a set of sections with fixed footprint areas bound to an offshore platform of a given size based on safety considerations due to fire, explosion, ...
Shock Interaction with Dust Layers
(2015-06-02)
Dust explosion hazards in areas where combustible dusts are found have caused loss of life and halted business operations in some instances. The elimination of secondary dust explosion hazards, i.e. reducing dust dispersion, ...
Corrosion Detection and Prediction Studies
(2012-10-19)
Corrosion is the most important mechanical integrity issues the petrochemical industry has to deal with. While significant research has been dedicated to studying corrosion, it is still the leading cause of pipeline failure ...
Normalization of Process Safety Metrics
(2012-10-19)
This study is aimed at exploring new process safety metrics for measuring the process safety performance in processing industries. Following a series of catastrophic incidents such as the Bhopal chemical tragedy (1984) and ...
Developing Process Safety Indicators for Organizational Factors in Petrochemical Industries
(2015-07-09)
Most major process safety incidents are preventable and can be avoided as shown in several incident investigation reports. Moreover, these reports indicated that these incidents were certain to occur as shown from the ...
