A “clean” combustion process that includes carbon dioxide sequestration may get its first commercial-scale tryout in Jamestown, N.Y., where the Jamestown Board of Public Utilities (BPU) is planning to replace two old, coal-fired boilers by a 43-MW circulating fluidized bed (CFB) boiler. Startup is planned for 2012. The BPU and its team of advisers have agreed to incorporate the oxy-coal process in the...

    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 bulk-solids stream must be raised, for example to bring about a chemical reaction in a subsequent processing step. Alternatively, a reduction in temperature is sometimes needed, for...

Researchers from the fluid-dynamics laboratories at CSIRO Manufacturing and Materials Technology (Melbourne, Australia; edlinks.che.com/6898-534) have developed a new heat-exchange technology, called RAMeX, which performs heat exchange and mixing of highly viscous fluids without stirrers, impellers, baffles and plates. Like the Rotated Arc Mixer (RAM; CE, February 2001, p. 17) from which it evolved, the...

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...

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...

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...

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...

    It's no secret that the chemical process industries (CPI) are being significantly impacted by the recent increases in energy costs. According to the U.S. Department of Energy, the CPI's percentage of total operating costs that are attributable to energy range from about 7% to over 30%. Because of such intensive energy use, these industries - including manufacturers in chemicals, pulp and...

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...

    Environmental regulations, the economy, an aging infrastructure and the always growing demand for energy are well-known factors driving the need to reshape today’s power generation industry. But how the pending changes will impact the chemical process industries (CPI) may come as a surprise. Once new technologies such as clean coal and advanced nuclear come online, end users in the CPI...
