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,…
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…
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…
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…
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;…
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…
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…
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…
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…
