This article offers a detailed reliability-based methodology for determining the safety integrity level of instrumented systems by providing overpressure protection where arrangements of multiple pressure-relief valves are impractical to implement.

Poor design, inadequate maintenance, and improper operation can all lead to mechanical failure. The basic concepts of pressure relief, when understood and applied properly, can help prevent this failure

If certain chemicals lack physical hazards data, suppliers must be proactive to keep workers safe. Here’s how to determine dust flammability and reactivity data for inclusion on MSDSs.

Between March and April 2010, a powerful but seemingly limited computer worm, now referred to as Stuxnet, infected computers around the world, beginning in Iran and spreading to Indonesia and India. A recently published book uncovers findings on the origin of the worm and raises concerns that are relevant to chemical engineers everywhere.
