Developed two decades ago, Metso Outotec’s (MO; Helsinki, Finland; www.mogroup.com) Circored process is now being reintroduced as a proven way to help decarbonize the ironmaking process. Developed in the 1990s by the former Lurgi Metallurgie (now part of MO) and…
An expanding number of products are demonstrating the real-world feasibility of incorporating post-consumer polyethylene (PE) into asphalt paving for roadways and parking lots. The set of demonstration projects — part of the New End-Market Opportunities (NEMO) program, under the auspices…
Topsoe A/S (Lyngby, Denmark) today announces its intention to construct world’s largest and most advanced industrial-scale electrolyzer production plant. Topsoe’s ambition is to rapidly accelerate the adoption of green solutions in particular within Power-to-X. In this field, the company has…
A new category of electrolysis could significantly lower the expenses associated with producing “green” hydrogen. In the new capillary-fed electrolyzer cell — designed by Hysata (Wollongong, Australia; www.hysata.com) based on research from the University of Wollongong (www.uow.edu.au) — water is…
The guidance provided here can help to mitigate problems occurring in pumping systems used for condensate recovery Condensate recovery is crucial to energy reduction and water conservation in a steam-using plant. It reduces effluent discharge and treatment requirements, as well…
NITROGEN UTILIZATION Late March, the first nitrogen fertilizer produced from a wastewater-treatment plant sidestream was delivered to a farm in Sweden. The fertilizer was produced at a pilot plant that began operation last December at Ragn-Sells Högbytorp’s (www.ragensells.se) wastewater-treatment and…
Before being fed to the blast furnace, iron ore is first converted into pellets by, for example, a traveling-grate (TG) pelletizing plant. In this plant, so-called green pellets are conveyed through a furnace that heats the pellets to high temperatures…
Strain on demand for critical battery metals is forcing manufacturers to seek alternative materials. Sulfur’s high thermal stability and abundance are making it a promising emerging battery material. A new class of solid-state lithium-sulfur batteries developed by Theion GmbH (Berlin,…
A new catalyst-coated membrane (CCM) technology for hydrogen production, developed by Honeywell UOP (Des Plaines, Ill.; uop.honeywell.com), is undergoing performance validation testing in partnership with manufacturers of proton-exchange membrane (PEM) and anion-exchange membrane (AEM) electrolyzers. Made from both proprietary UOP…
Last month, Vale S.A. (Rio de Janeiro, Brazil; www.vale.com) began construction on the first commercial plant to use its Tecnored process, which produces pig iron with biomass instead of metallurgical coal (coke). Located in Marabá, in the southeast of Pará,…
