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…
Following regulations for drinking water, increasingly stringent limits for per- and polyfluoroalkyl substances (PFAS) in industrial wastewater are anticipated, necessitating improved technology to handle higher rates of removal, as well as to destroy the compounds in concentrated samples. Gradiant (Boston,…
Polyvinyl chloride (PVC) is among the world’s most widely used polymers. Recycling PVC via mechanical and high-temperature chemical processes is challenging due to its chlorine content.The startup company Plastic Back (Tel Aviv, Israel; www.plastic-back.com) aims to raise the rates of…
A hazardous-materials storage system with climate control The WHS hazardous-material storage system (photo) features intelligent air conditioning to combat extreme weather, and to allow storage of substances that must be stored under precise temperature conditions. The integrated heating and cooling…
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.;…
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…
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…
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…
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…
A new research study by ETH Zurich (www.ethz.ch), in collaboration with BASF SE (Ludwigshafen, Germany), has investigated an alternative route for mixed plastic waste streams from end-of-life vehicles: to recycle it alongside biomass. The results show: the recycling of one…
