Biomass has come center stage in the pursuit of reduced dependence on finite - not to mention geopolitically sensitive - quantities of fossil fuels such as petroleum, coal and natural gas. And while ethanol produced from corn…
A new-type of polymer composite has recently been commercialized by Ceram Polymerik Pty Ltd. (Melbourne, Australia; edlinks.chemengonline.com/6517-533) for passive fire-protection applications. Passive fire protection consists of using a material or structure that confines fires, giving people more time to escape…
The ANSI/ISA-S84.01-1996 standard, which has guided North American users for the past decade in designing safety instrumented systems (SIS) has migrated to a new international standard based on the IEC 61511 and is now known as ANSI/ISA-84.00.01-2004 (IEC…
Researchers from the Physics of Fluids and Biocolloids group at the University of Granada (Spain; edlinks.chemengonline.com/6516-549) are developing a system in which bitumen emulsifies at room temperature, which facilitates transport and allows cold application. Because the bitumen does not need…
For many years, the job of a control room operator at a petroleum refinery or chemical plant was seen as relatively simple: Keep the process running and fix it when it breaks. That perception is changing as more…
As it has for several years, the U.S. Environmental Protection Agency (EPA) once again paid tribute early this summer to companies, as well as to an individual, for contributions to pollution prevention, via its Presidential Green Chemistry Challenge Awards competition.…

Researchers at Pacific Northwest National Laboratory (PNNL; edlinks.chemengonline.com/6515-533) have demonstrated a new process for treating water contaminated by toxic perchlorate ions, found in drinking water in 35 U.S. states. As in conventional treatment methods, the process uses ion exchange to…
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…
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…
