PVC polymer chlorination with LEDs enhances resin stability

Lubrizol (Cleveland, Ohio; www.lubrizol.com) recently began producing chlorinated polyvinyl chloride (CPVC) resin in commercial reactors equipped with light-emitting diodes (LEDs) as the light source, instead of the conventional mercury lamps. The company’s LED reactor technology enhances the thermal stability of…

Low-temperature plasma process supports direct recycling of battery cathodes

Direct battery-recycling methods, such as re-lithiation — where depleted lithium is replenished directly onto cathodes via a solid-state reaction — hold many benefits over indirect methods, such as those relying on hydrometallurgy or pyrometallurgy, where cathodic structures are destroyed in…

Electrochemical-redox process expands recycling potential for LFP batteries

Lithium-iron-phosphate (LFP) batteries offer a compelling combination of performance characteristics for stationary energy storage, including improved safety and longevity, when compared to other lithium battery chemistries, such as nickel- and cobalt-based formulations. However, there are limited recycling pathways dedicated to…

Gas-fed, solid-state electrolyzer could allow ethylene from waste-derived syngas

Conventional ethylene production via steam cracking of ethane or naphtha leads to the emission of 1 ton of CO2 for every ton of ethylene produced. Given the carbon intensity of the process and the annual volume of ethylene produced (300…

Customizing Bulk-Solids Mechanical Conveyors for the CPI

For effective mechanical conveying of bulk solids in the chemical process industries (CPI), equipment should be tailored to the specific needs of the solids-handling application The sheer diversity of bulk-solid materials encountered across the chemical process industries (CPI), including agricultural…

Editor’s page: From ‘automated’ to ‘autonomous’

The continued and expanding use of digitalization technologies in the process industries have pushed facility operations from “automated” — featuring distributed control systems, programmable logic controllers, safety instrumented systems and others — toward “autonomous” operations, where technologies like machine-learning, open-software-defined…
