Recycling materials, such as plastics and metals, is an attractive, but challenging path toward sustainable material manufacture. Now, researchers have made a discovery that may have far-reaching implications in material manufacture by positioning carbon nanotube (CNT) fibers as a sustainable…
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;…
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…
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…
In December 2024, the Pacific Northwest National Laboratory (PNNL; Richland, Wash.; www.pnnl.gov) announced a three-year collaborative project with vehicle-tire manufacturer Bridgestone (Tokyo, Japan; www.bridgestone.com) to scale up a thermocatalytic process for converting renewably derived ethanol to n-butene. Conventionally, n-butene is…
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…
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…
As processes have become more complex and dynamic, alarm management software has evolved, and now provides deep intelligence to keep plant personnel safer, more aware and more efficient There can be little doubt that effective alarms are one of the…
Developments in heat exchange technologies promote efficiency, reliability and cost effectiveness in the chemical process industries (CPI) Heat exchange technologies play a pivotal role in industrial sustainability efforts because they are at the forefront of enabling more environmentally friendly chemical…
Construction is imminent for a carbon-capture project aimed at reducing CO2 emissions from steel production while producing carbon-neutral calcium carbonate. At the U.S. Steel (Pittsburgh, Pa.; www.ussteel.com) manufacturing facility in Gary, Ind., a carbon-capture system designed by CarbonFree (San Antonio,…
