Chementator: This packing material keeps produce moist, while preventing water contact

A patented moisture-control technology (MCT) developed by CSIRO Plant Industry (edlinks.chemengonline.com/5827-534), with cooperation from Stellar Films Group (both Melbourne, Australia; edlinks.chemengonline.com/5827-535), has shown it can maintain field freshness of selected fruit and vegetables during extended periods of storage and shipping.…

Chementator: Slash water and energy requirements with this dyeing process

The conventional way to dye textiles is by the so-called dip process, whereby cloth is first immersed into a vat of the dying medium, then removed and dried. The dye is then thermally fixed to the textile by heating to…

Chementator: A ‘litmus’ test for heavy metals

Toshishige M. Suzuki and his colleagues at the Tohoku Center of National Institute of Advanced Industrial Science & Technology (AIST; Sendai, Japan; edlinks.chemengonline.com/5827-538) has developed a new analytical test strip that can quickly detect parts-per-billion (ppb) concentrations of heavy metal…

Chementator: New software should speed up reaction engineering

Simulations of chemical processes that involve many reactants with continually changing compositions can be set up and run in minutes, rather than the previously required hours, with a newly commercialized software package, Reaction Engineering Lab, says developer Comsol (Stockholm, Sweden,…

Chementator: Selective flotation

The presence of arsenic minerals, such as enargite and tennantite, in some copper-bearing ore bodies, can be a problem for those wishing to recover the copper. When delivering copper concentrates to smelters in Australia, for example, miners are subjected to…

Chementator: Converting trees into biodegredation plants

Large tracts of land that have been used for military training, especially in the U.S., are contaminated with RDX— a widely used explosive that is both toxic and carcinogenic. Although bacteria have been isolated that can biodegrade the RDX, the…

Chementator: Reduce gas consumption with this sparging nozzle  

A gas-liquid nozzle that reduces the size of the gas bubbles blown into a liquid — thus increasing the rate at which the gas is absorbed into the liquid — has been developed by a research team led by Jie…

Chementator: Improved catalysts are now ready for hydrotreating petroleum fuel

Haldor Topsøe (Lyngby, Denmark; edlinks.chemengonline.com/5826-533) has introduced two new hydroprocessing catalysts, which are based on its proprietary BRIM technology. Both catalysts are nickel-molybdenum types that optimize both hydrogenation at so-called brim sites (situated on the basal-plane of the catalyst) and…

Chementator: Catalyst screening

Lanxess Deutschland GmbH (Leverkusen, Germany; edlinks.chemengonline.com/5826-548) has commissioned a parallel reactor for the screening of catalysts use in hazardous reactions, such as phosgenation and chlorination, which are commonly used to make fine chemicals. Up to now, existing automated screening devices…
