  Silverado Green Fuel, Inc. (Vancouver BC, Canada; edlinks.che.com/6900-533) has entered into a memorandum of understanding with the Mississippi Development Authority (Jackson) to build a demonstration plant in Choctaw County to produce a clean-burning “green” liquid fuel from the state’s plentiful lignite reserves. Scheduled for startup in 2009, the plant will convert 30,000 ton/yr...

DuPont (Wilmington, Del.; edlinks.che.com/6900-531) has acquired hydrotreating technology for desulfurizing motor fuels and hydrocracking intermediate refinery streams from Process Dynamics, Inc. (Fayetteville, Ark.). The IsoTherming Hydroprocessing Technology differs from other hydrotreating processes in that hydrogen is dissolved in the liquid feed before the liquid enters the reactor, so the reactors...

Although halons (brominated or chlorinated fluorocarbons) are widely used as fire suppressants and foaming agents, they also contribute to stratospheric ozone depletion. However, halons are potentially valuable chemicals that should not be destroyed, but rather converted to reusable chemicals, says Bogdan Dlugogorski, professor of chemical engineering in the school of...

  Daicel Chemical Industries Ltd. (Osaka, Japan; edlinks.che.com/6900-540) is further developing an oxidation catalyst based on N-hydroxyphthalimide (NHPI), which was first discovered by Professor Yasutaka Ishii of Kansai University several years ago (CE, September 2000, p. 23). The catalyst, together with a small amount of metal salts (Mn or Co), can be used for the...

    Kermit the Frog once said, “It isn’t easy being green.” While this may be true, industry is still making the effort. Both in the U.S. and abroad, processors are not only striving to produce environmentally friendly products, but also are becoming more mindful of the impact of their operations. More often than not, cleaning up both products and processes requires the use of...

    Fouling is one of the most vexing problems in water-treatment systems that use membranes to remove suspended and dissolved particles. The deposition and accumulation of these substances on membrane surfaces inevitably lead to loss of performance for the membrane [1]. While there are several strategies for reducing fouling, the right solution varies with the process and type of fouling.  ...

  Climate change has become an important strategic issue for many operating companies throughout the chemical process industries (CPI). Public interest is increasing,1 shareholder interest continues to mount,2 and climate policy discussions are actively taking place at the state, regional, and federal levels.3 Developing an effective corporate strategy for managing climate change, to measure, track...

For the 12th straight year, the U.S. Environmental Protection Agency (EPA) has recognized efforts in developing less-toxic alternatives to existing technologies and reducing or eliminating waste in the manufacturing process. The 2007 Presidential Green Chemistry Challenge Awards, which are described briefly below (Source: EPA), were presented earlier this summer at a ceremony held in Washington, D.C. The...

Global Resource Corp. (GRC; West Berlin, N.J.; edlinks.che.com/6897-534) is commercializing a technology that converts auto shredder residue (ASR) into combustible gases, liquid fuels and scrap metal using microwaves. The use of microwaves to achieve this goal has been attempted in the past, but GRC is one of the first to succeed at an economically viable level, says GRC’s chief engineer Hawk Hogan. Unil...

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...

Paques B.V. (Balk, Netherlands; edlinks.che.com/6897-535) has developed a cost-effective biological process (flowsheet) for removing phosphates and nitrogen from wastewater. The first commercial installation to use the new process officially opened last month at Aviko (Steenseren, Netherlands), where it is treating 3,000 m3/d of wastewater from potato processing. The plant is owned and operated by...

The impact of the chemical process industries (CPI) is much farther reaching than just the products that they produce. With respect for the power of the materials they handle, the CPI must act responsibly, considering factors that can affect workers, the community and the environment. A recent visit to two of Degussa’s production facilities in the U.S. gave an inside look as to how one company...

    Although sealing technologies rarely make the headline, when they do, its usually for a tragic reason, which demonstrates how important this small component really is. For example, on January 28, 1986, the Space Shuttle Challenger disintegrated 73 seconds into its flight, after an O-ring seal in its right solid rocket booster (SRB) failed. The seal failure caused a flame leak from the SRB...

Polylactic acid (PLA) is a commercially available biodegradable polymer used in many nonfood products as an alternative to petrochemical-derived polymers. However, PLA's physical properties limit its use in many applications. Scientists at the USDA’s Eastern Regional Research Center (ERRC; Wyndmoor, Penn....
