Process Safety in Power Plants

May 1, 2013
Maria Clara Saraiva
Process Safety is a very common and used topic in the chemical industry. According to CCPS, an incident is reported as a process safety incident if it meets all four criteria (process involvement, above minimum reporting threshold, location and acute release). In the first criteria, a process must...

Using near Misses to Improve Risk Management Decisions

May 1, 2013
Brenton L. Cox, Russell A. Ogle, Sean J. Dee
In the process safety literature it is often claimed that the analysis of near-miss incidents can improve process safety performance. However, empirical research has demonstrated that near-miss events are interpreted as marginally successful, leading to riskier behavior due to lower perceived risk...

Novel Development of Asset Integrity Management for Refinery Equipment: Theory, Application and Effect of Setting Critical Operational Tan and Sulfur Level for Distillation Units

May 1, 2013
Dingrong Qu, Shanjun Mu, Xiaohui Liu, Xiu Jiang
Nowadays, refineries are continuously challenged by the low-grade crudes with increased concentration of sulfur and naphthenic acid. Operators need to know the limits of Total Acid Number (TAN) and sulfur content for their distillation units to avoid unexpected accelerated corrosion, which may lead...
