Safety-centered process control design based on dynamic safe set
(Mary Kay O'Connor Process Safety Center, 2019)
Despite significant efforts to make operation of chemical plants safer, the occurrence of incidents clearly indicates the need for better design approaches. Studies to identify the root causes of incidents in hydrocarbon ...
Heavy gas concentration prediction on complex terrain using CFD with Monin-Obukhov similarity theory
(Mary Kay O'Connor Process Safety Center, 2019)
Under stable atmospheric conditions (i.e., low wind speed and low heat radiation), once heavy gases (e.g., CO2, H2S, LNG) release to the atmosphere, the gas clouds tend to stay near the ground for long period of time, ...
Building Siting Screening Criteria for Structural Failure Hazards to Occupants
(Mary Kay O'Connor Process Safety Center, 2019)
Evaluation of occupied buildings for accidental explosion hazards at petrochemical facilities is a vital part of a process safety program and is a key element of facility siting. In some cases, buildings may be screened ...
Inherent Safety as a driver for business success in the Oil & Gas Industry
(Mary Kay O'Connor Process Safety Center, 2019)
Inherent safety is not a new concept and is recognized in the oil and gas industry following the works of Trevor Kletz [1] and others dating back to the 1970s. However, despite the progress made to date in the process ...
The Nature of Flammable Cloud Volumes in Semi-confined Environment under the Influence of Flow of Air
(Mary Kay O'Connor Process Safety Center, 2019)
In the Explosion Risk Analysis (ERA), ventilation and dispersion calculations using Computational Fluid Dynamics (CFD) are usually considered when the level of confinement and congestion cannot be neglected. As far as the ...
