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...

During the design phase of a project, vendor packages (e.g., compressors, water desalination) are typically treated as a "black box" with a very specific function, and the typical perspective of the buyer/owner/operator is that safety issues have been thoroughly vetted, based on the package vendor...

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...

The purpose of Process Hazards Analysis (PHA) is to identify and understand the hazards associated with the process being reviewed, to understand the potential resultant hazardous events, and to prevent those events by identifying all the potential routes to those events and ensuring that adequate...

OSHA's National Emphasis Program (NEP) on refineries has concluded. The two most cited elements of the Process Safety Management standard (PSM - 1910.119) in the NEP were Mechanical Integrity and Process Hazard Analysis (PHA). [1] This session will focus on common problems in PHA and how to avoid...

Process risk is a function of both the likelihood of occurance of an incident, and of the consequences of the incident. There is a common perception that inherently safer design focuses solely on reducing or eliminating the consequences. However, inherently safer design can also focus on the...

The best time to apply the principles of inherent safety is during the early stages of a design. In particular it is at the early stages that the ?Eliminate? option is best applied. For example, in the early stages of one design the process engineers had come up with a system of three knockout...

The use of dynamic modeling for relief system design can result in a considerable reduction in capital expenditure while simultaneously improving plant safety. This paper considers the application of dynamic analysis to two areas, vessel depressurization and flare network design, in order to...
