Phosgenation scaleup At the end of July, Bayer MaterialScience AG (BMS; Leverkusen, Germany; www.bayerbms.com) successfully tested its new gas-phase phosgenation technology at a new plant being commissioned for making toluene diisocyanate (TDI) — a raw material for making polyurethane —…
A process to greatly enhance the ability of sand to filter heavy metals from water has been developed by researchers from Monash University, of Melbourne, Australia (www.monash.edu.au), Rice University (Houston; www.rice.edu) and Nanoholdings LLC (Marietta, Ga.; www.nanoholdings.com). Historically, the researchers…
Metabolix Inc. (Cambridge, Mass.; www.metabolix.com) has successfully demonstrated and completed research and development for scaleup on a fermentation process that produces gamma -butyrolactone (GBL) from genetically engineered bacteria. The process is built upon the company’s technology for engineering metabolic pathways…
Since the isolation of graphene by the “Scotch tape” method, many researchers have tried to synthesize solution-dispersible graphene. The challenge has been to develop a high-yield method that can exfoliate graphite efficiently into solution-dispersible graphene sheets without collateral damage to…
Today only a few percent of Canada’s oil sands resource is accessible by traditional surface mining, so the rest has to be recovered in situ, mostly by steam-assisted gravity drainage (SAGD). In this process, steam is injected into a horizontal…
A new yeast strain that could one day substitute for petroleum as a source of surfactants for detergents, soaps and cosmetics has been identified by researchers at the U.S. Dept. of Agriculture’s National Center for Agricultural Utilization Research (Peoria, Ill.;…
Mitsubishi Chemical Corp. (MCC; Tokyo, www.m-kagaku.co.jp, MCC) is developing bio-based technology for producing propylene, butadiene, 1,4-butanediol (BDO), terephthalic acid and succinic acid from glucose. In collaboration with North American partners, MCC plans to start production of succinic acid and 1,4…
A joint venture (JV) between Vadxx Energy LLC (Akron, Ohio; www.vadxx.com) and Greenstar Recycling (Houston; www.greenstarrecycling.com) plans to start up a facility in mid-2012 to convert recovered plastics to synthetic crude oil. When complete, the facility will produce 80,000 bbl/yr…
Almost by definition, chemical engineering is a “green” discipline today, as it so often involves efforts to optimize chemical processes in order to reduce the amount of energy and raw materials that are used and the amount of waste that…
An alternative desalination process that reduces energy consumption by over 50% compared to best available technology (BAT) has been successfully piloted by the Industry Sector of Siemens AG (Munich, Germany; www.siemens.com), in collaboration with Singapores national water agency, PUB, and…
