Single-step process for electrified ethylene production
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…
Deepwater RO could cut energy use and environmental impact of seawater desalination
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;…
On-demand ammonia production from atmospheric air
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,…
Facts At Your Fingertips: Blending and Segregation Mechanisms for Solids
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…
