Mercury removal Scientists at Flinders University (Adelaide, Australia; www.flinders.edu.au) have further characterized their sulfur-limonene polysulfide polymer (Chem. Eng., December 2015, p. 12) to understand the conditions under which it can be used as a mercury sorbent. In a recent issue…
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…
Electrochem Technologies & Materials Inc. (Montreal, Canada; www.electrochem-technologies.com) produced pure electrolytic iron (99.995% Fe) using its patented FerWIN process (diagram) — a sustainable zero-carbon iron-making technology — from ferrous sulfate heptahydrate (copperas) originating from the sulfation of bauxite residues. This…
Ammonia produced using renewable energy is poised to be a crucial part of the hydrogen value chain as a mechanism for storing and transporting hydrogen. By combining two state-of-the art technologies for ammonia production and hydrogen storage, Hydrofuel Canada Inc.…
As chemical manufacturers continue to seek renewable alternatives for fossil-fuel feedstocks, bio-based ethanol is poised to be a crucial raw material in the ethylene value chain for products from jet fuel to plastics. The range of novel-shaped alumina catalyst developed…
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…
