Sodium chloride aerosols are widely used as part of bronchial provocation tests to identify people with asthma, and those who wish to enter military or police service. To maximize their effectiveness, salt aerosol crystals should be as small as possible…
Bayer MaterialScience AG (BMS; Leverkusen, Germany; edlinks.chemengonline.com/5830-546) has developed a new process for producing toluene diisocyanate (TDI), a precursor for making flexible polyurethane foam. Without disclosing details, BMS says the process reduces investment costs by 20–30%, and energy consumption by…
At last month’s Achema conference (Frankfurt; May 15–19), Norbert Ullrich, chief engineer at Uhde GmbH (Dortmund, Germany; edlinks.chemengonline.com/5830-533) announced a first customer for and presented details about a new hydrogen-peroxide-based propylene oxide (HPPO) process, developed by Degussa AG (Düsseldorf, Germany;…
ATMI Life Sciences (ATMI; Hoegaarden, Belgium; edlinks.chemengonline.com/5830-549) and Pierre Guérin SAS (Mauze sur le Mignon, France; edlinks.chemengonline.com/5830-550) have formed an alliance to design, manufacture and market disposable fermentors and bioreactors. ATMI’s proprietary mixing system (which features a paddle integrated into…
Professor Yasutaka Ishii, and colleagues from the Dept. of Applied Chemistry, Kansai University (Osaka, Japan; edlinks.chemengonline.com/5830-535), has developed a three-step production process to make epsilon-caprolactam (CPL) from cyclohexane. Compared to alternative methods, the process has a higher CPL yield, generates…
With funding from the U.S. Dept. of Energy (DOE; Washington, D.C.), Ramgen Power Systems (Bellevue, Wash.; edlinks.chemengonline.com/5830-536) is developing a compact supersonic compressor that combines aspects of the shock-compression systems used in supersonic flight inlets with proven turbomachinery design practices…
Researchers at Pacific Northwest National Laboratory (PNNL; Richland, Wash.; edlinks.chemengonline.com/5830-537) have developed a ceramic-based coating for steel and superalloys that prevents corrosion, oxidation, carburization and sulfidization, which commonly occur in gas, liquid, steam and other environments. The low-cost, easy-to-apply material…
Warwick Effect Polymers (WEP; Coventry, U.K.; edlinks.chemengonline.com/5830-540) has licensed patented technology from Carnegie Mellon University (Pittsburg, Pa.; edlinks.chemengonline.com/5830-541) to exploit the commercial potential of atom-transfer radical polymerization (ATRP). ATRP is a controlled “living” polymerization involving radicals that can grow, but…
Corrosion has the chemical process industries seeing red in their metal tanks and pipelines — and on the bottom line, too. In the U.S., for example, chemical, petrochemical and pharmaceutical producers incur direct costs of $1.7 billion/yr for corrosion, or…
An industrial group, composed of Honeywell, Adaptive Instruments, Endress + Hauser, Flowserve, Omnex Control Systems, 3e Technologies International, and Yokogawa, have joined the Instrumentation, Systems, and Automation Society (ISA; Research Triangle Park, N.C.; edlinks.chemengonline.com/5830-542) SP100 working group (chartered last year)…
