Risk Measures Constituting Risk Metrics for Decision Making in the Chemical Process Industry
(2012-02-14)
The occurrence of catastrophic incidents in the process industry leave a marked legacy of resulting in staggering economic and societal losses incurred by the company, the government and the society. The work described ...
Development of an Experimental Facility for Flame Speed Measurements in Powdered Aerosols
(2012-10-19)
Research with heterogeneous mixtures involving solid particulate in closed, constant-volume bombs is typically limited by the powder dispersion technique. This work details the development of an experimental apparatus that ...
Facility Siting and Layout Optimization Based on Process Safety
(2012-02-14)
In this work, a new approach to optimize facility layout for toxic release, fire and explosion scenarios is presented. By integrating a risk analysis in the optimization
formulation, safer assignments for facility layout ...
Liquefied Natural Gas (LNG) Vapor Dispersion Modeling with Computational Fluid Dynamics Codes
(2012-10-19)
Federal regulation 49 CFR 193 and standard NFPA 59A require the use of validated consequence models to determine the vapor cloud dispersion exclusion zones for accidental liquefied natural gas (LNG) releases. For modeling ...
Development of a Vapor Cloud Explosion Risk Analysis Tool Using Exceedance Methodology
(2012-10-19)
In development projects, designers should take into consideration the possibility of a vapor cloud explosion in the siting and design of a process plant from day one. The most important decisions pertinent to the location ...
Analysis of Innovative HVAC System Technologies and Their Application for Office Buildings in Hot and Humid Climates
(2012-02-14)
The commercial buildings sector in the United States used 18 percent (17.93 Quads) of the U.S. primary energy in 2006. Office buildings are the largest single energy consumption category in the commercial buildings sector ...
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 ...
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 ...
