A significant contributor to the cost, energy consumption and carbon footprint of silver production is in the refining steps to remove, recover and recycle zinc from Parkes Crust silver-zinc intermetallic compounds. A fundamental redesign of the silver process to improve…
As wind energy takes a prominent role in the energy transition, researchers at the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL: www.nrel.gov) have focused on manufacturing sustainable turbine blades that can be made from bio-derivable resources and then…
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,…
Facility monitoring, LED lighting and low-impact cleaners help reduce carbon footprint at chemical process industries (CPI) facilities It is not always possible to refine a process to help reduce a facility’s carbon footprint; however, embracing some newer trends in more…
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…
There are many categories of air contaminants that may be encountered in industry, from volatile organic compounds to aerosols to viruses, as well as a range of particulate matter and ultra-fine particles, which also vary greatly in size and properties.…
Industrial electrolysis involves passing a direct electric current through an electrolyte to elicit a range of chemical reactions. Electrolyzers are key pieces of technology for producing many important industrial chemicals. This one-page reference reviews the basic general operation of an…
This compressor extends horsepower and flow range The newly launched SFC 110M variable-frequency-drive compressor (photo) extends the SFC product series to 150 hp, with a 110-kW permanent-magnet motor, and enhances the flow range up to 742 ft3 /min at 100…
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…
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…
