Gas compressibility can lead to choked flow in piping systems. Presented here is an overview of choked-flow geometries in pipes, and examples of how choked flow arises in different pipe layouts The more things change, the more they stay the…
This company has recently secured full ATEX Zone 22 certifications for its EX200 and EX205 2-hp dust-control fans (photo). These fans are designed explicitly to provide proactive protection against fugitive combustible dust in hard-to-reach areas, enabling users to operate more…
Desalination of seawater with reverse osmosis (RO) membranes is a key technology for addressing water scarcity issues around the globe, but seawater desalination is energy-intensive and the brine discharge can create coastal environmental problems. The company Flocean AS (Oslo, Norway;…
This company’s explosion-proof sensor (photo) combines near-infrared technology with robust safety features, providing accuracy and reliability in explosive atmospheres. This sensor offers protection through a certified explosion-proof enclosure with conduits, unions, elbows and nipples for secure external connections. Even in…
Nearly all ammonia is produced using methane via the Haber-Bosch process, which requires high-temperature and high-pressure operation. A new portable prototype device developed by researchers from Stanford University (Stanford, Calif.; www.stanford.edu) and King Fahd University of Petroleum and Minerals (Dhahran,…
The potential of membrane technology to unlock hybrid and scalable carbon capture, combined with results from early field trials, suggest that advanced membranes will play a crucial role in enabling more widespread adoption of decarbonization strategies It is a truth…
A sophisticated approach to fire and explosion safety requires one that expands conventional protection strategies to comprehensively consider storage, containment and tool compatibility Industrial fires and explosions are a serious risk to chemical processing facilities worldwide, threatening significant harm to…
The Helix flexible screw conveyor (photo) features a helicoid screw that rotates within a fixed tube to transport materials efficiently from one point to another. It supports horizontal conveying up to 80 ft and vertical discharge heights of up to…
Thin gold films offer a broad range of benefits for electronics due to their high electrical conductivity and transparency. Current manufacturing methods are unable to achieve gold films thinner than 10 nm, and are also limited in the area and…
Sinamics G220 (photo) is a new multi-purpose, adjustable-speed drive that features built-in technology to reduce harmonics by up to 97% — without the need for an a.c. line reactor or d.c. choke. Sinamics G220 drives have an integrated web server…
