Making cement with 70% lower CO2 emissions
A process commercialized by Fortera Corp. (San Jose, Calif.; www.forteraglobal.com) creates a cement product that reduces CO2 emissions by 70% on a ton-for-ton basis, and can be blended with conventional cement or used as a standalone material to make ready-mix…
Chementator Briefs
E-Cracking Last April, BASF SE (Ludwigshafen, Germany; www.basf.com), SABIC (Riyadh, Saudi Arabia; www.sabic.com) and Linde Engineering (Pullach, Germany; www.linde-engineering.com) inaugurated the world’s first demonstration plant for large-scale electrically heated steam-cracking furnaces. Following three years of development, engineering, and construction work,…
New microreactors and flow loops improve asphaltene management
Asphaltenes are an ultra-complex fraction of crude petroleum that comprise a diverse population of molecules that vary in size, solubilities, aggregation states and hetero-atom contents. Asphaltene buildup and deposits create many operational and safety issues, and can occur anywhere in…
On-demand electric heat can reach near-flame temperatures
Electrification provides an avenue for industrial decarbonization, but many electric-heating options cannot handle the high temperatures and scale required for industrial use. Electrified Thermal Solutions (ETS; Medford, Mass.; www.electrifiedthermal.com) has taken a new approach to industrial heating through its JouleHive…
Isotope-enrichment process starts commercial production
Traditional isotope enrichment to separate radioactive atoms is highly capital intensive, and the supply chains for the materials are constrained, with the majority of enriching capability located in Russia. In a bid to expand isotope availability and lower costs, ASP…
Next-generation encapsulation technology
Nucleic acid-based medications, such as mRNA vaccines, are opening up new therapeutic approaches. These active ingredients must be enclosed inside nanoparticles to ensure that they get to where they are needed inside the body’s cells. The Fraunhofer Institute for Production…
A versatile sorbent that can clean metals from wastewater at a lower cost
At the 2024 Spring Meeting of the American Institute of Chemical Engineers (AIChE; www.aiche.org), a team from the National Energy Technology Laboratory (NETL; www.netl.doe.gov) presented on a recently patented technology for the removal of critical and heavy metals from wastewater…
Extracting useful proteins from beer-brewing leftovers
Brewers’ spent grain (BSG) is the most significant byproduct of the beer-brewing industry, making up 85% of the total waste. Globally, about 36.4 million ton/yr of spent grain are produced. This spent grain is typically discarded after its primary use…
Electrochemical sensor selectively detects dangerous bacteria
Researchers at Goethe University Frankfurt (www.uni-frankfurt.de) and Kiel University (both Germany; www.uni-kiel.de) have developed a new sensor for the detection of bacteria. It is based on a chip with a surface coating that ensures only very specific microorganisms, such as…
Improving sodium-ion batteries with nanocellular graphene
Nanocellular graphene (NCG) is a specialized form of graphene that achieves a large specific surface area by stacking multiple layers of graphene and controlling its internal structure with a nanoscale cellular morphology. Although the material has the potential to improve…
