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…
Drying can be defined as the vaporization and removal of liquids from a solution, suspension or other solid-liquid mixture to form a dry solid. Drying occurs as a result of the vaporization of liquid by supplying heat to wet solid…
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;…
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…
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…
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…
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.;…
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…
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,…
