As the nanoparticle market continues to swell, expertise is surfacing about nanoparticle grinding and dispersion processes. A grinding solution (wet grinding with agitator bead mills) achieves the production of nanoparticles with an average fineness of 40–100 nanometers (nm).…
These helical mixing elements are for several process applications Kenics Sanitary Static Mixers (photo) perform efficient, cost-effective handling of processing applications such as blending, dispersion and heating or cooling. Continuous inline mixing is achieved with no moving parts,…
Union connections are now part of this mixing valve’s design Ideal for multiple-outlet, point-of-use applications, or with small hot-water heaters, the Model 220-USW thermostatic mixing valve (photo) is now being touted for its availability with union connections. The…
This organization has specified PROFIsafe for wireless networks The new version of the PROFIsafe profile (Version 2.4) describes the conditions for the functionally safe transmission of data via WLAN and Bluetooth. The concept has been approved by the…
Although brown coal accounts for about 25% of Australia’s energy supply, it has a high moisture content and, when burned, is a high emitter of carbon dioxide (above 1,200kg/MWh). To address this challenge HRL Ltd. (Melbourne, Australia; edlinks.chemengonline.com/6897-531) has developed…
A dehydration process — which uses about half the energy required by thermal methods for drying brown coal or sludge — is being developed by the Central Research Institute of Electric Power Industry (Tokyo, Japan; edlinks.chemengonline.com/6897-532). The process uses liquefied…
Hydrogen is produced directly from biomass and other carbonaceous materials, with simultaneous capture of carbon dioxide, in a process being developed by Energy Quest, Inc. (Edmonton, Alta., Canada; edlinks.chemengonline.com/6897-533). In the PyStR (pyrolytic steam reforming) process, crushed or shredded feedstock…
The ST 3000 Pressure Transmitter line from Honeywell International, Inc. (Phoenix, Ariz.; edlinks.chemengonline.com/6897-546) is said to be the process industries’ first to support HART 6, the latest digital-communication protocol of the HART Communications Foundation (Austin, Tex.). The new interoperability gives…
While statistics from the U.S. Bureau of Labor Statistics (BLS; Washington, D.C.; www.bls.gov) and trends reported by the American Chemistry Council (ACC; Arlington, Va.; www.americanchemistry.com) suggest chemical engineers seeking work may be singing the blues, chemical processors and…
Deregulation of market pricing structures, increased oil-and-gas exploration and drilling costs, fierce competition, and new regulatory requirements have all influenced today’s trend toward quality flow-measurement methodologies. Not only is volume a consideration, but so is the inherent value…
