With the exception of Oslo-type crystallizers, the main commercial crystallizers are agitated systems that use an agitator [agitated tank or draft-tube baffle (DTB)] or a circulation pump [forced circulation (FC) crystallizers]. In such systems, however, large crystals become damaged by…
Many methods have been developed for the encapsulation of "active" materials within a carrier nanoparticle, such as a polymer. These composite structures can be used in many biomedical, cosmetics, and food processing applications for the controlled release of pharmaceuticals, neutraceuticals,…
Aqueous Recovery Resources, Inc. (ARR; Bedford Hill, NY; www.suparator.com), has developed the Suparator, an oil/water separation system that involves no moving parts or media, for low operational costs and minimal maintenance. The separator (diagram) is based on the Bernoulli effect,…
Cambrios Technologies Corp. (Sunnyvale, Calif.; www.cambrios.com) has formed a strategic partnership with Chisso Corp. (www.chisso.co.jp) and Sumitomo Corp. (both Tokyo; www.sumitomocorp.co.jp) for commercialization of Cambrios’ first product, ClearOhm coating material. Targeted for the liquid crystal display (LCD) market, ClearOhm is…
The American Society of Testing Materials (Conshohocken, Pa.; www.astm.org) has developed a new standard for measuring viscosity: ASTM D 7483-08, Determination of Dynamic and Kinematic Viscosity of Liquids by Oscillating Piston Viscometer (OPV). The new ASTM method is part of…
Arkema (Colomes, France; www.arkema.com) and hte (Heidelberg, Germany; www.hte-company.de) have successfully concluded a research collaboration aimed at identifying new catalysts for the conversion of glycerol — a byproduct of biodiesel production — to acrolein (2-propenal) and acrylic acid. The collaboration,…
A process that produces hydrogen from coal with close to 80% energy conversion efficiency, plus coproduction of a carbon-dioxide-rich stream for sequestration, is being developed at Ohio State University (Columbus, Ohio; www.osu.edu). This compares with around 60% conversion efficiency for…
In the framework of the Impulse project (Integrated Multiscale Process Units with Locally Structured Elements; CE, April 2005, p. 19), researchers from the Industrial Chemistry Group at RWTH Aachen University (Germany; www.itmc.rwth-aachen.de) have developed a continuous production plant capable of…
Mitsubishi Chemical Corp. (MCC; Tokyo, Japan; www.m-kagaku.co.jp) has developed a new technology for producing 1,3-butadiene (butadiene) from waste butenes using a self-developed, proprietary catalyst. The process has been pilot tested (200-ton/yr capacity) at MCC’s Mizushima site in Japan, and the…
A less-expensive way of making the raw materials for carbon anodes (for aluminum smelting) and graphite electrodes (used to make steel in electric arc furnaces) has been developed by West Virginia University (UWV; Morgantown, W.Va.; www.wvu.edu). The conventional starting materials…
