Linde Gas (Murray Hill, N.J.; edlinks.che.com/6897-538) and partners have developed a high-pressure gas-delivery system that allows coating powders to be sprayed using liquid nitrogen at temperatures that do not melt the powder particles. The system has been optimized to support a new, cold spray gun technology, called Kinetiks 4000, manufactured by CGT GmbH (Ampfing, Germany). Such a system is being...

What is billed as the world’s first plant to produce liquefied natural gas (LNG) from landfill gas is now being commissioned in Irvine, Calif., by Prometheus Energy Company (Seattle, Wash.; edlinks.che.com/6897-540). The first module is expected to reach its capacity of around 5,000 gal/d (about 750 scf/min of gas) by fall, says Dan Clarkson, vice-president. Other modules will be added later to use...

    While statistics from the U.S. Bureau of Labor Statistics (BLS; Washington, D.C.; www.bls.gov) and trends reported by the American Chemistry Council (ACC; Arlington, Va.; www.americanchemistry.com) suggest chemical engineers seeking work may be singing the blues, chemical processors and chemical engineering professors are belting out a very different tune. According to BLS’s 2000 to...

    Deregulation of market pricing structures, increased oil-and-gas exploration and drilling costs, fierce competition, and new regulatory requirements have all influenced today’s trend toward quality flow-measurement methodologies. Not only is volume a consideration, but so is the inherent value of the product being measured. From high-value process streams found in the pharmaceutical...

  A high-shear reactor that is said to accelerate chemical reaction rates by up to three orders of magnitude will get its first commercial tryout in the production of biodiesel fuel. Kreido Biofuels, Inc. (Camarillo, Calif.; kreido.com), the reactor's developer, will shortly start up a unit for Foothills Bio-Energies (Lenoir, N.C.; edlinks.che.com/6896-531), where it will add 1 million gal/yr to the...

Kobe Steel Ltd. (Kobelco; Tokyo; edlinks.che.com/6896-532) has developed a process to recover hydrogen from methane steam reformers with purity that is sufficiently high for use in fuel cells. The key to the process is a proprietary carbon-monoxide adsorbent for H₂ pressure-swing adsorption (PSA), which Kobelco developed jointly with Kansai Coke and Chemicals Co. (Amagasaki, Japan). In conventional PSA...

The standard way to produce ethanol from agricultural waste involves acid hydrolysis to convert hemicellulose to glucose, which is then fermented to obtain ethanol. However, cellulose in the waste is not converted, so cellulase enzymes are generally used to hydrolyze the cellulose to fermentable sugars, a slow and costly process. Researchers at the U.S. Dept. of Agriculture’s...

A process that promises to improve the economics of ethanol production by coproducing a marketable adhesive is being developed by the USDA's Dairy Forage Research Center (Madison, Wis.; edlinks.che.com/6896-534). Another benefit is that ethanol is made from cellulosic material in a single reactor, rather than the normal two-step method of breaking down cellulose to obtain glucose, then fermenting the...

ConocoPhillips LP (CP; Houston, Tex.; edlinks.che.com/6896-539) and Tyson Foods, Inc. (Springdale, Ark.) have formed an alliance to use beef, pork and poultry by-product fat to create renewable-diesel (RD) fuel that burns cleaner than conventional diesel. The production technology uses a thermal depolymerization (TDP) process developed by CP that co-processes animal fat (supplied by Tyson) with hydrocarbon...
