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…
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.…
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…
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…
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,…
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…
Tire recycling The Mitsubishi Chemical Group (MCG; Tokyo, Japan; www.mcgc.com) has demonstrated chemical recycling of end-of-life tires (ELTs) using the coke ovens at its Kagawa Plant (Sakaide City, Kagawa Prefecture). The company is able to feed crushed ELTs as raw…
A significant portion of the energy and cost requirements in the production of lithium-ion batteries stems from the cost of converting lithium sulfate or lithium chloride into lithium hydroxide monohydrate (LHM) of sufficient purity for battery use. Noram Electrolysis Systems,…
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…
Currently, medical waste streams are complicated to recycle because these single-use products — such as facemasks, syringes, nitrile gloves and non-woven gowns — consist of multiple materials and must be considered contaminated with potentially infectious particles. Now, researchers at Chalmers…
