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…
Developing sustainable pathways to ethylene — among the world’s most widely used chemicals — is a key element in decarbonizing the process industries. A new electrolysis technology developed by CERT Systems (Toronto, Ont., Canada; www.co2cert.com) can produce ethylene from CO2…
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 solids-handling, blending (combining two or more materials to achieve a combined product) and segregation (the separation of particles into distinct zones according to particle size, shape, density or other physical attributes) are competing processes. This one-page reference outlines common…
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,…
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,…
Monitoring capabilities for shared laboratory spaces This product, launched as part of this company’s Dashboard solution (photo), is designed to add alerting capabilities to centrally located devices within a shared laboratory space, such as a cleanroom. The product introduces visual…
The wide range of performance properties of polyurethane foams makes them essential in many consumer goods. Thus, there is much effort going into creating a more environmentally friendly production process for polyurethane’s main building blocks, polyols and isocyanates. While much…
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…
Designing a proton-exchange membrane that will balance the efficiency, durability and safety requirements for hydrogen production requires careful consideration of materials and chemistry Among the ongoing efforts to curb climate change, researchers are actively pursuing the further development of water…
