Controlling Process Variables for Solid-State Battery Performance
Optimizing electrical conductivity in next-generation batteries depends on carefully controlling process variables, such as mixing, particle-size distribution and temperature. Presented here is a discussion of how these process variables affect battery performance In the evolving landscape of energy storage technologies,…
Separating Hazardous Materials with Decanter-Centrifuge Systems
Sealed and gas-purged decanter-centrifuge systems can be effective for separating Class I, Div. 1-, or Class I, Div. 2-rated solvents and hazardous materials Traditionally, solids and liquids have been separated by filtration or with press equipment. While these methods are…
Pad-Reinforced Nozzles in Pressure Vessels
This article examines the application of reinforcing pads for strengthening nozzles in pressure vessels and the impact of the geometric gap that exists between the pad and the vessel shell Many common forms of nozzle connections in technological applications are…
Lithium Landscape: Activity is Charging Forward in the U.S.
Across several regions of the U.S., new lithium projects are emerging to build up a more localized supply chain Despite growing demand in the U.S. for batteries in consumer electronics and electric vehicles (EV), the vast majority of lithium extraction…
Averting Disaster: Delivering Value from Sensors and Alarms
A strategic approach to asset and alarm management will reduce alarm fatigue, mitigate risk and support more effective response On April 20, 2010, an explosion on the Deepwater Horizon offshore drilling rig (owned by Transocean and operated by BP) killed…
Advancing battery technologies
Last month, the U.S. Department of Energy (DOE, www.energy.gov) announced that two Energy Innovation Hub teams would receive a total of $125 million ($62.5 million to each team) in funding over five years to “seed and accelerate next-generation technologies beyond…
Holistic Maintenance and Reliability Programs
When updating equipment protection systems in a plant, it often pays to think long term. Today’s protection systems can do more than avoid catastrophic failure — they are the foundation of an enterprise-wide predictive maintenance program Chemical process industries (CPI)…
Process for continuous production of MOFs plans scaleup
Metal-organic frameworks (MOFs) have shown great potential for a number of applications, including as carbon-capture materials, but their use commercially has been limited by production methods, which are generally expensive batch processes. With the development of a continuous process for…
