In late December 2025, a system that uses electric fields — rather than mechanical means — to generate nanometer-sized gas bubbles entered operation at a commercial site in Saudi Arabia. The nanobubble-generating technology was developed by the startup company AquaB…
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…
Variable-frequency drives designed for ease-of-use The EZ VFD® family of variable-frequency drives (photo) for¼- to 2-horsepower (hp) applications are feature-rich models designed for ease of installation and usage. They are plug-and-play for most applications and include easily adjusted trimpots for…
Polystyrene (PS) is among the more difficult-to-recycle fractions of plastic waste, but could be a source of valuable aromatic petrochemicals, such as toluene. Prior approaches to convert PS to toluene have exhibited low yields and a range of products. Now,…
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…
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…
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 processes are vital for recovering ethanol from…
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…
The rise of artificial intelligence (AI) and high-performance computing (HPC) technologies has presented the chemical process industries (CPI) with opportunities for improving process efficiency, asset maintenance, product development and plant safety. While not fully realized in the CPI, the potential…
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…
