Process Safety Technical Areas

While Safety Instrumented Systems (SIS) can be an essential element of process facility design to minimize the potential for process incidents, in some cases they can also be over-applied in the design phases of capital projects where the Safety Instrumented Functions (SIFs) associated with the SIS...

The discussion of societal risk criteria for the process industry began in the 1970's, led primarily by the Dutch and British governments. Most of the discussion, however, has centered on fixed facilities. The literature on the societal risk of hazardous goods transportation, particularly by...

To perform LOPA's, fault tree analysis, SIL verifications and other quantitative likelihood analyses requires data. As much as everyone wants data, it always seems to be elusive or lacking in quality. This paper explores various issues that the authors have experienced when dealing with end user...

Evaluation of Dust Explosion/Fire Hazards during a Process Hazards Analysis [PHA] Mayur Patel DuPont Engineering mayur.patel@ind.dupont.com and S. Dharmavaram DuPont Engineering seshu.dharmavaram@usa.dupont.com Many of the recent dust fire and explosion incidents have shown that PHA teams have...

Taking a Risk for Safety Over the last twenty years companies in the process industries have invested heavily in their occupational safety programs. These investments of time and money have been made in many areas, including training, behavior-based safety and the use of PPE. The results have been...

The focus of most laboratory experiments and piloting operations is the development of a new, innovative chemical process or the improvement of an existing chemical process. These activities are designed to, and focus on, evaluation of the intended chemistry for the process being studied. The...

A release of flammable substances can result in various fire or explosion events depending on whether there is an immediate or delayed ignition. Although developments have taken place in producing fit-for-purpose ignition models, there remain significant uncertainties, including how to identify the...

Abstract AIChE Housten Conference April 1-4 2012 Loss Of Containment Protection Auto Refrigeration and Metal Embrittlement Tys Koerts Sr. Process Safety Consultant Auto-refrigeration occurs on adiabatic expansion of gasses and boiling of liquids. The resulting low temperature can bring metals like...

Learning from the experiences and expertise of others has long been recognized as a valued process when completing PHAs. The gathering of a multi-disciplinary review allows facilities to succeed in a path of continuous improvement by evaluating the current and future state of the process based on...
