Process Knowledge Management

Increasing the safety and security within the chemical supply chain has been a concern of the US government for several years. Both the Environmental Protection Agency (EPA) and the Department of Homeland Security (DHS) have active efforts to reduce societal risk of a toxic industrial chemical...

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...

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...

Improving Conduct of Operations Using Best Practice Tools from Operating, Engineering, and Management Discipline Jerry Forest Global Process Safety Manager Celanese 1601 West LBJ Freeway Dallas, TX 75234 (214) 417-1920 Jerry.forest@celanese.com Abstract Conduct of operations concerns how work is...

Integration of the process safety in the chemical engineering curriculum is a requirement. Several places exist and with a multitude of approaches. One approach we have used in our unit operations laboratories for over 30 years is an introductory treasure hunt, mandatory during the first meeting of...

There has been a dramatic approach in the way we are implementing process safety guidelines and standards for combustible. This is particularly true for North America where there have been devastating dust explosions occurring for the last 10 years or so. Following this, OSHA has initiated NEP,...

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...

Strong acids, such as aqueous hydrochloric acid, are commonly used in the chemical process industry to purify streams or remove particulates from raw material, product, and waste streams. The benefits of HCl are its' low cost, large dissociation constant, and stability over time. However, the...
