Next April, a six-year, €4-million project will begin that aims to develop an electrochemical process to recover halogens (chlorine, bromine and fluorine) from waste products. Funded as part of the CZS Breakthrough program of the Carl Zeiss Foundation (CZS; Heidenheim…
A new electrowinning process is being field-trialed at the Prieska copper-zinc mine operated by Orion Minerals Ltd. (Melbourne, Australia; www.orionminerals.com.au) in South Africa, which will enable the production of valuable products, including calcium, magnesium, iron and others, from contaminated mine…
LanzaTech Inc. (Chicago, Ill.; www.lanzatech.com) has developed a genetically engineered bacterium capable of converting carbon dioxide directly to ethylene, the most widely used chemical building block globally. The company has incorporated the engineered biocatalyst into a continuous process in a…
Li extraction A new technology is going to be introduced at the Schlumberger NeoLith Energy direct lithium-extraction (DLE) project in Clayton Valley, Nev. Developed by Gradiant Ventures (Boston, Mass.; www.gradiant.com), the technology enables high levels of lithium concentration (while simultaneously…
In late October, Metso Outotec Corp. (Helsinki, Finland; www.mogroup.com) introduced the DRI (direct reduced iron) Smelting Furnace to substitute blast furnaces used in iron- and steelmaking. The furnace was developed to tolerate high-slag volumes, which are problematic for a conventional…
Liberty Steel UK (LSUK; London; www.libertysteelgroup.com) has completed trials of ecoke — a sustainable new raw material that can replace anthracite, the main source of charge carbon used in the electric-arc furnace (EAF) of steelmaking, and reduce steel’s carbon footprint…
Chlorum Solutions LLC (São Paulo, Brazil) will use thyssenkrupp nucera AG & Co. KG (Dortmund, Germany) technology for its next two chlor-alkali plants in Brazil. The company has ordered two skid mounted plants with BM2.7 electrolysis technology from the supplier…
The use of hydrogen brings unique safety challenges, especially explosion risks. As its use grows across industries, effective explosion protection becomes essential. Understanding the principles, practices, and technologies behind explosion protection ensures reliable operations and safeguards people, equipment, and the…
Magnesium metal is important for several emerging potential sustainability-related applications, including carbon capture, low-carbon cement and energy storage. These potential applications are driving efforts to efficiently produce magnesium hydroxide, the raw material for manufacturing Mg metal. It is possible to…
An emerging electrolyzer technology for renewable hydrogen production is the anion-exchange membrane (AEM), which provides efficiency and cost benefits over other electrolyzer configurations. Until now, most AEM installations have been small, as the membrane assemblies’ size and durability limited the…
