As new regulations take effect, familiar refrigerants are being phased out and a variety of next-generation materials and processes are being introduced Agreed upon in October 2016 after negotiations from over 170 nations, the Kigali Amendment to the Montreal Protocol…
Proper gas sampling is essential to meet operating and regulatory objectives Flares are used extensively in chemical process industries (CPI) facilities and petroleum refineries, to combust flammable hazardous gases. When designed and operated properly, they provide a proven mechanism to…
Sound levels in a plant or in a lab are often high enough to be distracting, and sometimes they are high enough to create health and safety concerns for workers in the immediate area. We've published a noise level calculator…
December 2015 marked a landmark international agreement to lower greenhouse gas (GHG) emissions in order to limit the rise in global temperatures to less than 2°C above pre-industrial temperatures. This agreement, made at the 21st Conference of the Parties to…
Plant layout is as important a part of process plant design as it ever was, but it is rarely taught as part of chemical engineering courses While process plant layout is a critical aspect of chemical process industries (CPI) operations,…
Be vigilant about parallel pumping conditions that can lead to catastrophic failures During my career, I have seen several massive centrifugal pump failures caused by pump users attempting to operate pumps in parallel without the proper equipment review, procedural review…
Early in 2016, OSHA (the Occupational Health and Safety Administration) announced its “final rule” regarding respirable crystalline silica. This rule has been under consideration since 2013. The final ruling reduces the permissible exposure limit (or PEL) for workers in businesses…
