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…
At the end of May, Teijin Twaron B.V. (Arnhem, Netherlands; edlinks.chemengonline.com/6897-543) opened a new pilot-production plant for producing a new generation of Twaron para-aramides pulp using a new jet-spinning process. The company did not disclose process details except to say…
Today, nearly all car tires in Europe are equipped with treads consisting of silica-silane technology. Such so-called green tires are made with the help of bifunctional organic silicon compounds (organosilanes) to chemically couple rubber and silica. Up to now, however,…
Last month, Rautaruukki Raahe Mills (Finland) started constructing a new pilot-scale acid-regeneration plant, which will regenerate hydrochloric acid used in pickeling hot-rolled steel at the mill. The plant marks the first commercial application of a recycling process developed by Kemira…
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…
