Eliminating the traditional electrolyte from electrolysis, a new electrolyzer design is aiming for higher efficiencies and lower costs in green hydrogen production. Tobe Energy (Oklahoma City, Okla.; www.tobe.energy) has developed a high-voltage all-stainless-steel electrolysis system that operates at much lower…
Nearly all of the currently produced building-block chemical acrylonitrile (AN) results from the ammoxidation of propylene, a process that requires precise heat control and generates several toxic side products, such as hydrogen cyanide. The startup company Mars Materials (Houston, Tex.;…
Understanding the forces acting on agitator impeller blades during turbulent flow in a mixing vessel is essential for successful and efficient operation. Presented here is information on the hydraulic force, its source, and how to calculate it Mechanically agitated vessels…
In lithium processing, advanced mixing technologies — applied across the crystallization, carbonization and decomposition steps — can serve as critical enablers in meeting efficiency, scalability and sustainability demands Lithium carbonate (Li2CO3) is a key raw material in the production of…
Plant Watch World-scale black pellet plant begins commercial operation in Vietnam October 14, 2025 — Idemitsu Kosan Co. (Tokyo; www.idemitsu.com) has commenced commercial operation of its newly constructed plant in Gia Lai Province, Vietnam, to produce black pellets (BP), a…
Processes to reuse plastics from end-of-life vehicles are complicated by solid contaminants — including pre-embedded metal and rubber components of different sizes and reinforcing glass fiber. Currently, recycling solids-containing waste-plastic parts is accomplished by physical sorting processes. Honda (Tokyo, Japan;…
Decarbonizing industrial process heat is challenging. Heat pumps offer a path to convert previously unused waste heat into low-carbon steam Industrial operations are notoriously difficult to decarbonize, but a project currently underway in Germany illustrates that there are viable pathways…
Carbon-fiber reinforced plastics (CFRPs) are used in a broad range of products, including automotive parts, construction materials and many others. Economically recycling these materials has proven challenging due to their multi-material makeup. Typically, they are chopped into pellets or strips…
As the hydrogen economy matures and production scales up, critical equipment like valves must evolve to ensure safe and optimized handling and transport According to the Energy Transition Council, the overall share of fossil fuels is expected to decrease significantly…
Electrically conductive plastics, also known as conjugated polymers, bring many cutting-edge benefits for flexible sensors, medical devices, energy-storage systems and more. They are currently produced at relatively small volumes and come with extremely high prices. A novel technology discovered at…
