Outotec Oyj (Espoo, Finland; www.outotec.com) has commercialized a new cooling tower that offers increased cooling capacity with significantly lower emissions to air when cooling solutions in metallurgical processes. The new tower can be used in a wide range of process…
Transport systems that can encapsulate medications for release when and where needed are the subject of much research and development, especially for two potential synthetic vessels: liposomes and multilayered polymer capsules. Both, however, entail limitations. The permeability of polymer capsules,…
Two sulfur-treatment technologies are being used together for the first time in a facility that is now starting up at Reliance Petroleum’s Jamnagar Export Refinery (Jamnagar, India). Designed by Black & Veatch (B&V, Overland Park, Kan.; www.bv.com), the facility combines…
A biological wastewater-treatment technology can reduce sludge by 50% or more in some situations compared to the amount generated by a traditional activated-sludge wastewater-treatment process, according to The Dow Chemical Co. (Midland, Mich.; http://www.dow.com). Actual sludge reductions vary based on…
Researchers from the University of Sydney (Australia; http://www.usyd.edu.au) are developing structures, analogous to some sea creatures, for capturing carbon dioxide that is released when producing hydrogen from biomass. The project, funded by German energy company E.ON AG (Düsseldorf), will use…
Both carbon dioxide and sulfur components are removed from fluegas in a reversible process being developed at Pacific Northwest National Laboratory (PNNL, Richland, Wash.; http://www.pnl.gov). The process uses a solvent that combines liquid organic bases (amidine and guanidine) and alcohols…
An in-situ method that removes mercury from soil, sludge and other industrial waste has been patented (U.S. Patent 7 589 248) by scientists at Brookhaven National Laboratory (BNL; Upton, N.Y.; http://www.bnl.gov). The method shows promise as a simple and inexpensive…
Nippon Shokubai Co. (Nisshoku; Osaka, Japan; http://www.shokubai.co.jp) is developing a process for making acrylic acid from glycerin directly obtained as a byproduct from biodiesel-fuel (BDF) production. In 2007, Nisshoku demonstrated, under a grant from the Research Institute of Innovative Technology…
Scientists at the Fraunhofer Institute for Molecular Biology and Applied Ecology (IME; Aachen, Germany; http://www.ime.fraunhofer.de) have genetically engineered Russian dandelions to make it easier to extract the plant’s milky latex. The scientists identified the enzyme responsible for the rapid polymerization…
The first commercially available, pentacene-based, organic semiconductor material is sufficiently soluble to render it amenable to solution-depositing methods, according to 3M (St. Paul, Minn.; http://www.3m.com). The company recently began marketing the product as semiconductor L-20856 (TIPS-pentacene) for low-cost transistors. Substitution…
