    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 are soaring). As a result, vendors of filtration equipment — be it for dust removal from fluegas or product recovery from a gas or liquid...

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.che.com/6897-531) has developed a variant of integrated-gasification, combined-cycle (IGCC) technology, called IDGCC (integrated drying and gasification...

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.che.com/6897-532). The process uses liquefied dimethyl ether (DME) as the dehydrating agent, taking advantage of the ether’s properties: namely, DME has a low boiling...

Hydrogen is produced directly from biomass and other carbonaceous materials, with simultaneous capture of carbon dioxide, in a process being developed by Energy Quest, Inc. (Edmonton, Alta., Canada; edlinks.che.com/6897-533). In the PyStR (pyrolytic steam reforming) process, crushed or shredded feedstock and steam are fed directly into a circulating bed of calcium oxide. The fuel is pyrolized at about...

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...

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...

Techno Bank Co., Ltd. (Tokyo, Japan; edlinks.che.com/6897-537) has developed a new supply, storage, and transport system for safely handling a high capacity of hydrogen in fuel-cell applications. The system — a cassette containing nano-sized powder of magnesium hydride (MgH₂) — is said to be safer than alternatives, such as insulated cylinders of liquid H₂ at 700 bar. Other methods being...

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...
