This article made available to you by: The troubleshooting methods described here can help engineers to understand operational realities when “running blind” in complex distillation processes One of the most critical aspects in ethanol production is the distillation unit. Distillation…
The chemical and physical properties of some solid materials render them prone to restricted flow and flow stoppages when discharging from bins and hoppers. This one-page reference outlines common solids-flow problems, as well as strategies and devices that can aid…
A PFAS-remediation project using sustainably manufactured granulated activated carbon for drinking water demonstrates how PFAS adsorption performance can be combined with reduced costs and environmental impact As thousands of public water systems across the country make plans to reduce per-…
Electrochemical water-treatment technologies facilitate the adsorption of ions, effectively removing contaminants such as calcium, magnesium, bromine and more. Such processes, however, are often hampered by the high costs associated with electrode regeneration and the use of ion-exchange membranes. A new…
A new structural material builds upon the promise of enzyme-enhanced CO2 mineralization to overcome decarbonization challenges in the construction industry. Researchers from Worcester Polytechnic Institute (WPI; Worcester, Mass.; www.wpi.edu), led by Nima Rahbar, head of WPI’s Department of Civil, Environmental…
The search for a new ammonia-synthesis method has now driven research and development work underground, literally. Addis Energy (Somerville, Mass.; www.addisenergy.com) is launching a subsurface synthesis technology that takes advantage of geologic chemistry to produce ammonia. “Addis Energy’s process uses…
Plant Watch Solstice announces manufacturing expansions in Germany and the U.S. January 15, 2026 — Solstice Advanced Materials (Morris Plains, N.J.; www.solstice.com) has completed two significant manufacturing expansions: a recently completed €5.5-million expansion of its stannous fluoride manufacturing facility in…
Post-consumer absorbent hygiene products (AHPs), such as infant diapers, feminine hygiene products and adult incontinence products, present unique challenges for recycling, because they contain compound materials like superabsorbent polymers and non-woven fabrics, as well as bio-hazardous waste, which are difficult…
Buildings lose considerable heating and cooling energy through their windows, so window coatings with low thermal conductivity would improve efficiency. However, finding insulating materials that are also transparent is a challenge. A team of researchers at the University of Colorado…
Ammonia manufacturing with carbon capture (blue ammonia) has emerged as the most practical near-term option for deep decarbonization of ammonia production. Evaluated here are eight technology configurations for decarbonization strategies with blue ammonia production Ammonia is increasingly viewed as an…
