With hydrogen’s evolution into an alternative fuel requiring precise production and storage, selecting the right valves has never been more important Hydrogen shows great promise in the search for alternative fuels. Handling hydrogen safely and reliably, from generation to end…
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…
The destruction of per- and polyfluoroalkyl substances (PFAS) presents unique issues in wastewater treatment, as these substances are persistent in many treatment environments, and PFAS-laden purification media is challenging to dispose of. Now, InEnTec Inc. (Richland, Wash.; www.inentec.com) says that…
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…
Acrylic acid, a commodity chemical used widely in superabsorbent polymers, paints, coatings, adhesives and more, is typically produced from fossil-based propylene at relatively high temperatures. As part of an initiative supported by the U.S. Dept. of Defense, funding was recently…
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…
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…
Because of their excellent mechanical properties, light weight and biodegradability, cellulose nanofibers (CNF) are attractive materials for next-generation reinforced biomaterials and bioplastics. However, the method for separating cellulose to make CNF, known as fibrillation, is energy-intensive, which limits applications for…
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…
Striving to make products and processes safer, more efficient, more sustainable, more economical and more environmentally friendly has long been the goal of research and applied scientists and engineers. For the past 28 years, new and innovative “green” chemistry technologies…
