Patent granted on system for feeding biomass to high-pressure reactors
One of the challenges for biofuels manufacturing is reliably feeding low-density feedstocks into high-pressure reactors, because it is difficult to feed agricultural and forest residue, as well as municipal solid waste, into pressurized systems without bridging, compaction and flow instability.…
Pilot project debuts integrated hydrogen storage and transport using aqueous-salt technology
Hydrogen production is expanding across the globe, but hydrogen gas remains difficult and costly to store and transport, restricting its broader use. A pilot project in Germany is demonstrating for the first time a salt-based process for long-term hydrogen storage.…
Circular-loop recycling for disposable baby diapers demonstrated in Europe
Disposable baby diapers are a challenging waste stream, because the absorbent polymers, non-woven fibers and organic material prevent them from mechanical-recycling processes. However, a three-way partnership has demonstrated a circular system for chemical recycling of disposable diapers. The project, involving…
Atomically thin photocatalysts unlock new pollution-degradation capabilities
Researchers at the University of Birmingham (www.birmingham.ac.uk) have demonstrated a new production method for ultra-thin catalysts, unlocking new capabilities for the catalytic breakdown of persistent water pollutants. “The production method takes layered materials as the precursor, disperses them in a…
Editor’s Page: Seeking Wise Counsel
The leadership expert Ken Blanchard said “None of us is as smart as all of us” — a phrase that applies to Chemical Engineering's process of editorial decision-making. One source of intelligence is the CE Editorial Advisory Board. We have…
Electrified process converts CO2 and biochar into industrial products
The production of salable co-products can substantially improve the economics for CO2 conversion processes. A new electrified thermochemical process developed by startup Reduciner Oy (Espoo, Finland; www.reduciner.com) combines captured CO2 streams with biochar to produce carbon monoxide, along with activated…
Facts At Your Fingertips: Particle Stress and Feed Requirements for Impact Milling
The chemical process industries (CPI) include many applications of impact comminution to process solid matter, such as minerals, chemical products, foods and pharmaceutical products. This one-page reference discusses conditions for particle fracture and feed characteristics in industrial milling equipment. Particle…
World-first sewage-treatment trial proves comprehensive dual-phase PFAS removal
An ongoing large-scale demonstration project in Australia is the world’s first to apply a foam-fractionation technology to remove per- and polyfluoroalkyl substances (PFAS) in a sewage-treatment plant. The Surface-Active Foam Fractionation (SAFF®) technology developed by EPOC Enviro (Emu Plains, NSW,…
Tower Doctor: Should a Doctor Diagnose by a Hunch?
Henry Kister shares lessons learned from troubleshooting distillation towers The C2 splitter tower is the final step in ethylene plant distillation. It separates a high-purity ethylene top product (typically a few hundred ppm ethane impurity) from the ethane recycle bottoms.…
Electrolysis at Scale: Unlocking Sustainable Lithium Hydroxide Production
Electrolysis-based lithium refining presents a promising alternative to conventional approaches, offering benefits related to reduced reagent consumption and effluent production, higher-purity products and an improved environmental footprint Electrolysis, a process that uses electric current to drive non-spontaneous chemical reactions, has…
