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…
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…
Synthesis of methanol from carbon dioxide is among the key goals for net-zero-CO2 production of chemicals and fuels. Previous investigation has suggested that indium oxide could serve as an effective catalyst for this reaction, but the structural details of the…
Plant Watch Nouryon expands production capacity for colloidal silica in China April 13, 2026 — Nouryon (Amsterdam, the Netherlands; www.nouryon.com) is expanding production capacity for colloidal silica at its manufacturing site in Guangzhou, China to serve fast-growing segments like emissions-control…
Ammonia is a critical input for agricultural fertilizers, but NH3 production is plagued by volatile prices, difficult global logistics and high CO2 emissions. A new NH3-production system from the startup TalusAg (Austin, Texas; www.talusag.com) addresses these challenges with a modular…
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…
A team of researchers at Iowa State University (ISU; Ames; www.iastate.edu) have developed a new bioreactor concept that streamlines production of value-added bioproducts at smaller scales by integrating three process steps (fermentation, product extraction and separation) into a single, compact…
Petroleum refiners are taking steps to support and increase operational flexibility and business agility as logistical challenges and economic headwinds build, and policy certainty is difficult to find Amid the current economic climate, business agility and operational flexibility have emerged…
This article made available to you by: This article provides an overview of the engineering, design and operational considerations associated with reactors and vessels, bridging the gap between theoretical design codes and applied process engineering Pressure vessels and reactors are…
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…
