Breaking the stable carbon-fluorine bonds within per- and polyfluoroalkyl substances (PFAS) is one of the most significant challenges in mitigating persistent PFAS pollution. The Hydrothermal Alkaline Technology (HALT; diagram), invented at the Colorado School of Mines (Golden, Colo.; www.mines.edu) and…
A first-of-its-kind energy-recovery system harnesses the energy of water flow and pressure in pipelines to produce renewable energy. The patented HydroXS unit, developed by InPipe Energy, Inc. (Portland, Ore.; www.inpipeenergy.com) in collaboration with Grundfos Corp. (Brookshire, Tex.; www.grundfos.com/us), is a…
Most existing carbon-dioxide removal (CDR) approaches have focused on air, but the volumetric concentration of dissolved inorganic CO2 in surface water is much higher (150X) than its concentration in the atmosphere. Removing CO2 from water could prove to be a…
Energy- and carbon-intensive, steel production is categorized as one of the most “hard-to-abate” industries, making the scaleup of decarbonization technologies crucial not only for steelmakers themselves, but for every downstream industry in the supply chain Responsible for some 9% of…
This month’s column gives a brief overview of the Chemical Engineering brand. While long-term readers need no introduction to the magazine, newer readers might be interested in the history of the magazine and what we cover. Perhaps even long-term readers…
Process analytical technology (PAT) approaches allow continuous monitoring and real-time control of processes. Among the key monitoring technologies is Raman spectroscopy, which offers inline measurement that can reduce personnel time and sampling complexity The chemical industry faces new challenges with…
