Filtration in the spotlight

    In the chemical process industries (CPI), pressure is constantly on to improve filtration. The filtration step has to be performed quickly (time is money), efficiently (product loss is money lost), and effectively (energy costs for pumping and drying…

U.S. EPA Honors Green Chemistry

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…

Using Bins & Silos To Heat or Cool Bulk Solids

    Vessels for handling bulk solids, such as silos and bins, are frequently used to heat or cool bulk materials in cases where a slow rate of change or long residence time is required. Often, the temperature of a…

Maintenance and Repair of Glass-Lined Equipment

 A customized inspection and maintenance program will minimize operational and performance problems with glass-lined equipment Glass-lined steel equipment is used in a wide range of chemical processes that involve harsh chemicals, including the production of pharmaceuticals, specialty chemicals, agricultural products…

A new type of coal-fired IGCC-power plant to be demonstrated

Although brown coal accounts for about 25% of Australia’s energy supply, it has a high moisture content and, when burned, is a high emitter of carbon dioxide (above 1,200kg/MWh). To address this challenge HRL Ltd. (Melbourne, Australia; edlinks.chemengonline.com/6897-531) has developed…

Liquified DME cuts energy costs for dehydrating solids

A dehydration process — which uses about half the energy required by thermal methods for drying brown coal or sludge — is being developed by the Central Research Institute of Electric Power Industry (Tokyo, Japan; edlinks.chemengonline.com/6897-532). The process uses liquefied…
