Follow these recommendations to select the right centrifuge for your application Many chemical process operations require the separation of multiple phases. This can be done in a number of ways, including simple gravity separation, traditional or crossflow membrane filtration and…
Last month, the U.S. Congress passed the Frank Lautenberg Chemical Safety for the 21st Century Act. This bill, called “historic” by many, brings very significant changes to the 40-year-old Toxic Substances Control Act (TSCA). This much-needed modernization of TSCA is…
At the April 2016 Seattle meeting of the ASME B31.3 Process Piping Code Committee, a presentation — a cautionary note in a manner of speaking — was given by Barry Messer of Fluor Corp. (www.fluor.com). The topic was the unexpectedly…
Ongoing advances in both adsorbent materials and system engineering allow today’s pressure swing adsorption (PSA) systems to produce nitrogen of varying purities and volumes at relatively low cost compared to cryogenic air separation Nitrogen production that is carried out using…
Cybersecurity is critical for plant safety. Principles developed for plant safety can be applied to the security of IT systems When the Stuxnet computer worm attacked programmable logic controllers (PLCs) at Iranian nuclear facilities running an integrated system, centrifuges were…
Security techniques widely used in information technology (IT) require special considerations to be useful in operational settings. Here are several that should get closer attention Industrial cybersecurity risks are widely appreciated. In April, the deputy director of the U.S. National…
