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....

            Many coal-fired power plants make gypsum and construction materials. But they should also consider manufacturing hydrochloric acid and ethanol. Furthermore, they should consider substituting biomass and waste organics for up to 10% of the coal. The combination of these initiatives would make coal plants much “greener.” Coal is the cost effective way to...

An integrated energy scheme that combines the generation of substitute natural gas (SNG) from coal, coproduction of biofuel and electricity and near-zero emissions of carbon dioxide, is being developed by Arizona Public Service (APS, Phoenix; edlinks.che.com/6895-532), Arizona’s largest utility, with the support of the U.S. Dept. of Energy’s National Energy Technology Laboratory (NETL...

    A detailed follow up of the cations present in the wastewater of the Monsanto Europe site in Antwerp, Belgium, has led to an increased understanding of changing wastewater treatment plant performance. The chemical process industries' (CPI) other wastewater treatment plants that handle continuously changing mixtures of different manufacturing plant effluents should also consider routine...

    Pure water is an essential ingredient in the manufacture of a vast amount of products in the U.S. and, of course, throughout the world. In the industry for which I work, electricity generation, high-purity water is an absolute must for feeding high-pressure steam generators. But of course, steam generation is also important in the petroleum-refining and petrochemical industries...

    China's tremendous economic growth and modernization has propelled the nation to a position where its consumption of energy imports outpaces its economy. As the world's third-largest oil importer, after the United States and Japan, China imported a record-high 36.38-million tons of refined oil last year, 15.7% more than in 2005, to fuel an estimated annual economic growth of 10.7%, reports...
