This company has developed WirelessHART instrumentation devices (photo) with batteries that are expected to last the entire life of the device. The batteries are engineered to minimize energy usage based on an in-depth microsecond-by-microsecond analysis of a unit’s power consumption.…
This company now offers protective light curtains for its tumble blenders (photo) to provide automatic safety shutoff whenever an operator crosses a defined security boundary. Due to the nature of the rotating mix chamber, a safety railing is supplied as…
The UltraPure model (photo) from the Unique Mixproof valve product line is designed to meet the standards of biotechnology and pharmaceutical applications. Valves are packaged to ensure full traceability and are available in high-alloy materials, such as Hastelloy C22 and…
Facilities with safety instrumented systems can now take advantage of the new SIL (safety integrity level) 2/3 functional safety certification of the Rosemount 8800 Vortex flowmeters (photo), per IEC 61508, which can help mitigate risk, enhance plant safety and protect…
All chemical process industries (CPI) operations involving combustion need to be concerned with the emission of combustion products, due to their potential environmental and health impacts. This one-page reference provides information about several of the most common combustion byproducts from…
This column is based on “Isopropyl Alcohol Production from RG Propylene – Cost Analysis,” a report published by Intratec. It can be found at: www.intratec.us/analysis/isopropyl-alcohol-production-cost. Isopropanol (isopropyl alcohol) is among the most commonly produced lower alcohols — ranked third in…
Predictive maintenance for rotating machinery is gaining prominence as plant operators embrace analytics and learn how to approach their operating benchmarks Rotating machines, such as motors, compressors, pumps and turbines, are critically important components of plant operations, and must perform…
With the proper knowledge, engineers can work alongside compressor manufacturers to ensure that an optimal air compression system is installed There are various factors to consider when designing a compressed air system that help to improve the reliability and efficiency…
Areas of recent activity for pressure-relief systems include new calculation methods and updates to existing codes and standards. Included here is an overview of recent developments and a look at the results from a recent study of pressure-relief system deficiencies…
Several methods are available for sizing two-phase pressure-relief valves (PRVs). Here, the API 520 homogeneous direct integration method is compared to a potentially simpler alternative that does not require integration Two-phase pressure-relief valves (PRVs) have been studied by many researchers.…
