The solvent N-methylpyrrolidone (NMP) has been used to coat anodes and cathodes in lithium-ion batteries, but it has been shown to be a reproductive toxin, necessitating controlled handling and recycling within a closed system, which adds complexity and cost to…
Significant sustainability benefits can be gained through optimization in steam-cracking furnaces. The study detailed here shows the specific decarbonization strategies that can help improve energy efficiency and reduce emissions The chemical process industries (CPI) rely heavily on steam cracking to…
Plant Watch BASF completes superabsorbent polymers expansion project in Texas October 16, 2024 — BASF SE (Ludwigshafen, Germany; www.basf.com) announced that its petrochemicals division has completed production upgrades for superabsorbent polymers (SAP) after a $19.2-million investment in its Freeport, Tex.…
Consider the potential for stem seal leakage when selecting a valve Experienced process control engineers follow familiar, time-tested steps when presented with a new system to design and specify. Selecting a control valve for a process always requires the same…
The electrolytes used in nearly all lithium-ion and sodium-ion batteries are carbonate-based, which makes them flammable and prone to degradation mechanisms, including side reactions, which can result in gas evolution and the formation of undesirable chemicals like hydrogen fluoride. A…
Electrifying industrial heat Calectra (Oakland, Calif.; www.calectra.com) has received $1.6 million in pre-seed funding and $400,000 in grant funding from the U.S. Government and New York State to support its work on decarbonizing industrial process heat. Heavy industrial processes, like…
Removing per- and polyfluoralkyl substances (PFAS) from surface and groundwater has become an environmental and public health imperative, but methods for doing so are often complicated and costly, and may not destroy the molecules. Researchers at the University of British…
Environmental imperatives drive the development of technologies for the chemical recycling of plastic waste, but significant hurdles – including economic viability, collection logistics and feedstock complexity – need to be addressed for chemical recycling to have a larger impact Plastic…
A handheld Raman device for material identification This company’s handheld 1,064-nm Raman Progeny analyzer (photo) is used for raw material identification, in-process analysis and authentication of finished products in pharmaceutical manufacturing. Traditional processes can include laboratory analysis, a costly and…
Coriolis mass flowmeters are available with a range of body styles and transmitters, enabling significant functionality improvements without sensor replacement Coriolis meters have long been a mainstay in the chemical process industries (CPI), providing highly accurate mass-flow measurements for raw-material…
