Replacing a pressurization blower with a turbocharger reduces energy use

Reductions in power consumption by over 30% have been observed at a full-scale formaldehyde production plant by introducing a new design in which a pressurization blower is replaced by a turbocharger that is powered by the exhaust gas from the…

A cheaper way to destroy organic contaminants?

An ultraviolet oxidation process for the destruction of water-borne organic contaminants that combines UV with chlorine, rather than hydrogen peroxide, is being developed by MIOX Corp. (Albuquerque, N.M.; www.miox.com). The company’s Advanced Oxidation Process (AOP) promises to be less expensive…

March Chementator Briefs

  Microelectrode Although antimony electrodes have been used for decades to measure pH, they only allow for measuring pH changes at a certain distance from electrodes or corroding surfaces. Now, researchers from the Institute of Physical Chemistry of the Polish…

A bi-metallic nanocluster catalyst for highly selective asymmetric C–C formation

Shu Kobayashi and his research group at the University of Tokyo (Japan; www.chem.s.u-tokyo.ac.jp/users/synorg/index_e.html) have developed a ruthenium-silver nanocluster catalyst for the highly selective 1,4-addition reaction for the formation of asymmetric carbon-carbon bonds. Previously, the group had used its polymeric incarceration…

Electrochemistry may have a future in CO2 cleanup

An electrochemical process that could cut the energy and cost requirements for stripping carbon dioxide from stack gases by half is being developed at Arizona State University (ASU, Tempe; www.asu.edu). At present the only commercially viable technology is CO2 absorption…

Physical chemistry principles point to a better way to clean up oil spills

One of the current methods for dealing with oil spills is through the use of dispersants. These dispersants, however, break oil into small globules that sink into the water, spreading the oil into a wider area, and they have toxic…

A process for recovering rare-earth metals from magnet scrap

Researchers at the U.S. Dept. of Energy’s (DOE) Ames Laboratory (Ames, Iowa; www.ameslab.gov) led by Ryan Ott have developed a process for recovering rare-earth (RE) metals from magnet scraps. The process involves first crushing neodymium-iron-boron magnet scraps and placing the…
