  2. CSB Investigation of Chevron Richmond Refinery Fire

    ChemE On Demand Presentation (AIChE Spring Meeting and Global Congress on Process Safety, 2013)

    On August 6, 2012 a hydrocarbon fire occurred at approximately 6:30 p.m. in the crude unit of the Chevron Richmond Refinery in Richmond, California. Approximately 20 workers were present when an 8" line ruptured and engulfed the employees in a vapor cloud. Five employees suffered minor injuries and...

  3. Case Studies in Process Safety: Lessons Learned From Software-Related Accidents

    ChemE On Demand Presentation (AIChE Spring Meeting and Global Congress on Process Safety, 2013)

    Abstract Software often plays a significant role in the safety of complex systems such as those used in the chemical processing and energy production industries. Because computing systems are increasingly being used to control critical functions, software may directly contribute to an accident...

  4. Effectiveness of Improvised Gas Absorption Techniques for Emergency Responders At Releases of Toxic Gases

    ChemE On Demand Presentation (AIChE Spring Meeting and Global Congress on Process Safety, 2013)

    In September 2011 a spill of nitric acid at a galvanic company in Trieben/Austria caused the release of large amounts of nitrous fumes. An IBC tank with 1000 liter of nitric acid (53%) was flipped over by a forklift and cracked open in the top area. The content was fully released and lead to...

  5. Calcium Stearate Deflagrations A Series of Unfortunate Events

    ChemE On Demand Presentation (AIChE Spring Meeting and Global Congress on Process Safety, 2013)

    A series of deflagrations occurred in a plant unloading Calcium Stearate from bulk bags. Each one had a different root cause and illustrates the importance of management systems for ignition control and the need to evaluate a system for many types of ignition sources. The first event was caused by...

  7. Improving Reliability & Safety Performance of Solenoid Valves by Stroke Testing

    ChemE On Demand Presentation (AIChE Spring Meeting and Global Congress on Process Safety, 2013)

    Solenoid valves integrated into the design of emergency shutdown valves (EDS) used in industrial process systems can tend to bind, i.e., to become stuck in one position, when not moved for long periods of time. This binding, also known as failure due to excessive stiction, has significant negative...
