A more economical process for bio-succinic acid piloted
Bio-based succinic acid has been explored as a renewable building-block for a host of chemicals and polymers, but its production process remains costly due largely to the complicated purification process that generates a large waste stream. Now, researchers at the…
Upcycling gypsum to sulfuric acid in a zero-liquid-discharge demonstration plant
A new demonstration plant is upcycling gypsum (calcium sulfate) — a material that is typically challenging to dispose of — at a metal-refining site using a process that combines salt-splitting electrolysis, caustic direct-air capture (DAC) and mineralization. Travertine Technologies, Inc.…
Catalyst developed for conversion of CH4 to methanol
Scientists at the Brookhaven National Laboratory (BNL; Upton, N.Y.; www.bnl.gov) and collaborating institutions have engineered a highly selective catalyst that can convert methane into methanol in a one-step reaction. The system could help make better use of “stranded” natural gas…
New injector technology fundamentally improves combustion flexibility
Conventional combustors that employ air-blast and pressure-swirl injection technologies are very sensitive to fuel properties, especially viscosity, limiting their ability to utilize certain classes of fuels and blends, including bio-based fuels. The new swirl-burst (SB) fuel-injector technology developed at Baylor…
Upgrading organic wastewater into fuel feedstocks
Although wastewater streams with high organic content — such as those from breweries and dairy facilities — can be difficult to treat and expensive to dispose of, there is potential to valorize their carbon content with the right process. Based…
Modern Level-Measurement Technologies for CPI Applications
Advanced level measurement devices enhanced with intelligence solve CPI challenges Chemical processes often require handling media that is corrosive, flammable, explosive or toxic with wide ranges in temperature and pressure and characteristics that include steam, dust, foam, turbulence and condensation.…
Plant Watch: December 2024
Plant Watch Evonik breaks ground on specialty-amine production plant in Nanjing November 11, 2024 — Evonik Industries AG (Essen, Germany; www.evonik.com) has broken ground on its plant expansion for specialty amines in Nanjing, China. The Nanjing plant specializes in producing…
A nearly universal electrolyte chemistry for safer, longer-lasting batteries
The electrolytes used in nearly all lithium-ion and sodium-ion batteries are carbonate-based, which makes them flammable and prone to degradation mechanisms, including side reactions, which can result in gas evolution and the formation of undesirable chemicals like hydrogen fluoride. A…
Process for electrolytically converting CO2 to carbon materials to be scaled up
With a recent round of investment funding, UP Catalyst (Tallinn, Estonia; www.upcatalyst.com) plans to build a pilot plant for a process that converts waste carbon dioxide into a range of solid carbon materials, such as carbon nanotubes, (CNTs), graphite and…
“Frugal” method adsorbs and destroys PFAS with photocatalyst
Removing per- and polyfluoralkyl substances (PFAS) from surface and groundwater has become an environmental and public health imperative, but methods for doing so are often complicated and costly, and may not destroy the molecules. Researchers at the University of British…
