Acetonitrile, a byproduct of acrylonitrile production, has been in short supply for about a year because of a dramatic reduction in the demand for acrylonitrile, used in plastics for the manufacture of cars, appliances and electronic goods. A process modification…
Last month, in unveiling the S-Series release of its DeltaV digital automation system, Emerson Process Management (Austin, Tex.; www.emersonprocess.com) introduced electronic marshalling, a new concept in input/output (I/O) configuration that promises to streamline the design and installation of automation systems,…
Rotec Ltd. (Ashkelon, Israel; http://www.rotec-water.com), a technology-transfer company of Ben-Gurion University of the Negev (BGN; Beer-Sheva, Israel), is developing a new desalination technology that promises to increase the water-recovery rate of reverse osmosis (RO) systems from 75–85% up to 95%.…
Process Systems Enterprise Ltd. (PSE; London, U.K.; www.psenterprise.com) is to make new advanced thermodynamic modeling tools for prediction of liquid and gas thermodynamic properties available through its gPROMS process-modeling environment. The technology makes it possible to considerably speed up the…
Foams based on corn starch may one day be substituted for polystyrene foams through technology being developed by the Agricultural Research Service (ARS, Beltsville, Md.; http://www.ars.usda.gov). The ARS Western Regional Research Center (Albany, Calif.) is working on two processes. One…
Retarded polymerization A latent-acid catalyst that can be added to highly reactive pre-polymer resins enabling them to be stored for at least three months prior to controlled polymerization at 120°C has been commercialized by Bac2 (Southampton, U.K.; http://www.bac2.co.uk). Alternative catalysts…
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…
