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 October, the Royal Swedish Academy of Sciences awarded the 2025 Nobel Prize for chemistry to three pioneers who were instrumental in the development of metal-organic frameworks (MOFs). Richard Robson (University of Melbourne; www.unimelb.edu.au), Susumu Kitagawa (Kyoto University; www.kyoto-u.ac.jp and…
Selecting the right technology to ensure accurate and reliable level measurement can help solve the unique challenges posed by storing and processing solid materials Advanced measurement solutions are helping to enhance process control, operational efficiency and safety throughout the chemical…
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,…
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…
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.;…
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…
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…
