A chemical-treatment process, called Kemicond, that reduces the volume and odor of sludge has been commercialized by its developer Kemitra Kemi AB Kemwater (Helsingborg, Sweden; edlinks.chemengonline.com/6515-532). The first commercial application - a system for Käppala Association (Stockholm, Sweden) that treats…
Among this year's award winners of the U.S. Environmental Protection Agency's (EPA; Washington, D.C.) Presidential Green Chemistry Challenge are Codexis, Inc. (Redwood City, Calif.; edlinks.chemengonline.com/6515-538), Merck & Co. (Whitehouse, N.J.; edlinks.chemengonline.com/6515-539) and Galen Suppes, professor of chemical engineering at the…
China, one of the world's great growth stories, may become the world's largest consumer market. As that potential unfolds, petrochemical activity and investment are sure to be key drivers. China is now the 6th largest economy in the…
Soil contaminated with chlorinated aliphatic compounds can be remediated ten times faster than with biological or iron-based methods by use of a new metallic powder developed by Tosoh Corp. (Tokyo; edlinks.chemengonline.com/6514-532). The powder, called MA-FN20, electrochemically strips the chlorine atoms…
Powerspan Corp. (Portsmouth, N.H.; edlinks.chemengonline.com/6514-535) is developing a process that uses an aqueous ammonia (AA) solution to capture COâ‚‚ from the fluegas (FG) of power plants. Results from a joint research project with the U.S. Dept. of Energy’s (DOE; Washington,…
Professor emeritus Kiyoshi Ohtsuka and his colleagues at the Tokyo Institute of Technology, Tokyo, Japan; edlinks.chemengonline.com/6514-538) have discovered a new process that produces pure Hâ‚‚ from cellulose. The process not only has nearly a 100% yield, but produces no CO…
Alfa Laval AB (Lund, Sweden; edlinks.chemengonline.com/5830-531) has developed a new reactor system, called Alfa Laval Plate Reactors (trademarked as ART), which combines the high-heat-transfer capabilities of plate heat exchangers with the efficient mixing and reaction control typical of microreactors into…
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…
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;…
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…
