Relaunching a process that uses 100% H2 for the direct reduction of iron ore

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…

Incorporating waste polyethylene into asphalt

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 to build world’s largest electrolyzer-production facility to accelerate Power-to-X capacity

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…

Capillary-fed electrolysis unlocks new levels of efficiency for green-hydrogen production

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…

Chementator briefs

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…

A new burner slashes NOx emissions from iron-ore pelletizing plants

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…

Catalyst-coated membrane reduces electrolyzer stack cost for H2 production

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…

Commercial debut for a process that makes ‘green’ pig iron

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,…
