Facts At Your Fingertips: Discharging Solids from Bins and Hoppers

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…

Troubleshooting an Ethanol Distillation Facility

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…

Selecting Blue-Ammonia Technologies

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…

Improving PFAS Remediation Performance

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-…

The Future Role of AI in CPI Compliance

Compliance in the chemical process industry (CPI) has become an increasingly complex endeavor, but artificial intelligence (AI) promises to help effectively navigate modern regulatory landscapes When it comes to compliance and safety in the chemical process industries (CPI), product stewardship,…

CPI support for data center expansion

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…

Subsurface synthesis could unlock a new source of ammonia

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…

Membrane-free electrochemical water-treatment method also generates power

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…

Quantum chemistry helps uncover path to safer ozone-based water disinfection

Ozone is seen an a safer and more environmentally friendly alternative to chlorine for water disinfection, but the efficient generation of ozone on-demand and at commercially relevant scales has been hindered by catalytic degradation problems. A team of researchers from…

New transparent insulator material could improve heat efficiency of buildings

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…
