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,…
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…
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.…
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…
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…
A temperature monitor to help reveal abnormal conditions The Synchros temperature monitor (photo) is designed to gather surface and ambient temperature data that can reveal abnormal conditions across assets such as pumps, heat exchangers, rotating equipment, steam systems and heat-tracing…
Plant Watch Air Liquide starts up CO2-capture pilot unit at Holcim cement facility June 11, 2026 — Air Liquide S.A. (Paris, France; www.airliquide.com) started up its first industrial-scale pilot unit specifically designed for the cement sector, based on its proprietary…
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.…
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…
INEOS Enterprises announced the completion of the sale of INEOS Calabrian, its ultra-pure sulfur dioxide and derivatives business, to Ecovyst Inc. (Malvern, Pa.). The transaction, valued at $190 million, marks the successful conclusion of a strategic divestment first announced in…
