Traditionally, many polymerization reactions are carried out batchwise in reactor vessels, with the reaction taking place in solution, emulsion or in a melt. This procedure reaches its limits if, for example, the reaction is very exothermic or the viscosity increases…
The efficiency of steam-generating and distribution systems can be improved incrementally, but more substantial gains can be found using pinch analysis for better heat recovery When it comes to improving the energy efficiency of a thermal system, most industrial organizations…
Plant Watch Agilyx polystyrene depolymerization plant commissioned in Japan June 7, 2024 — Agilyx ASA (Tigard, Ore.; www.agilyx.com) announced that its depolymerization technology was successfully demonstrated during commissioning of Toyo Styrene’s 10-ton/d chemical recycling facility in Japan. The recycling plant…
A research team led by Kenneth C. Neyerlin at the National Renewable Energy Laboratory (NREL; Golden, Colo.; www.nrel.gov), with members from Argonne National Laboratory (Lemont, Ill; www.anl.gov) and Oak Ridge National Laboratory (Tenn.; www.ornl.gov) has developed a membrane electrode assembly…
Effective slurry mixing for electrode material has a significant effect on the performance of a lithium-ion battery fabricated downstream. A collaboration improved the slurry-mixing ability and improved the quality of the electrode materials The global shift towards cleaner and more…
Calcium-sulfonate complex greases are widely used in applications in the pulp-and-paper, marine and steel-manufacturing sectors. Within an ever-volatile lithium market, calcium-sulfonate greases are increasingly seen as a reliable alternative to lithium-based greases. However, typical methods for preparing high-performance calcium-sulfonate grease…
The V-Cone Blenders utilize diffusion as the main mechanism for mixing. As the V-shaped vessel rotates on its horizontal axis, batch materials cascade down, distributing particles over a freshly exposed surface. With operating speeds of 5 to 25 rpm, this…
In a first-of-its-kind trial project, a CO2-removal method known as enhanced rock weathering (ERW) is being combined with biotechnology to accelerate atmospheric CO2 sequestration. FabricNano (London, U.K.; www.fabricnano.com) and Veolia (Paris, France; www.veolia.com) have embarked on a partnership wherein enzymes…
An Oak Ridge National Laboratory (ORNL) team created and tested two different formulations for stationary batteries that could utilize CO2 from industrial sources while storing energy from wind turbines and solar panels. Consisting of two electrodes in a saltwater solution,…
These air mixers (photo) are designed for maximum efficiency and ease of use in diverse mixing applications. Compatible with a range of mixing blades, these air-powered devices are intrinsically safe for handling of volatile and flammable materials when electric mixers…
