This article provides a comparative study of two approaches to protect ASME semi-elliptical pressure tanks from overpressure in the event of a fire Calculating the wetted surface area is a crucial step to protect American Society of Mechanical Engineers’ (ASME)…
Better upfront planning and management can lead to safer, more productive processes throughout every phase of operation A standards-based approach to process safety — one that actively addresses risks across a plant’s lifespan — can lead to safer chemical processes,…
Typically, the presence of condensation substantially degrades the measurement signal strength of ultrasonic sensors, but new EchoTouch reflective ultrasonic liquid-level sensors (photo) work in areas with condensation. By orienting the transducer vertically, condensation runs off the unimpeded transducer face to…
This company’s rugged fluid-bed dryers feature unitary steel bases as standard, which allow cover-lift hoists, process-air ductwork, control panels, monitoring instrumentation and other auxiliary equipment to be attached to the system as a single unit. Providing a dedicated, non-moving foundation,…
Cybersecurity is no longer a far-fetched concept relegated to science fiction or conspiracy theories. It is a major and growing global risk across all industry sectors Given the increasingly central role of digital technologies, data and connectivity, cybersecurity is widely…
This column is based on “Benzene Production from Pygas,” a report published by Intratec. It can be found at: www.intratec.us/analysis/benzene-production-cost. Benzene is the simplest and most important industrial aromatic hydrocarbon. It is a versatile petrochemical building block, and is an…
EtherCAT terminals (photo), part of this company’s ELX Series, have been expanded through the addition of analog input terminals with built-in TwinSAFE SC (single channel) technology. These highly compact I/O terminals can be used to support applications in hazardous areas…
The new 3561 FC vibration sensor (photo) improves uptime by adding remote, continuous vibration monitoring to virtually any rotating equipment. With a frequency range of 10 to 1,000 Hz, the 3561 FC detects and notifies users of conditional changes caused…
The TraceNet Genesis control and monitoring system (photo) manages heat-trace circuit performance on process lines, tanks and instrumentation. The TraceNet Genesis system gives instant access to comprehensive heat-trace circuit information, including circuit performance history, fault analysis and circuit drawings. Using…
The Chemineer RL-3 impeller (photo) has been specifically engineered to prevent fibrous material buildup on the rotating impeller. This rag-shedding impeller also provides a strong axial flow for efficient blending and solids suspension. The design allows for a safer process…
