As the price of electricity, natural gas and other fossil fuels continues to climb, chemical processors are more closely examining high-temperature operations and heat-transfer systems to see if more efficiency can be had. In many cases it can, and, as…
Japan Oil, Gas, & Metals National Corp. (JOGMEC; Kawasaki; edlinks.chemengonline.com/6902-534) and six private companies have established a research consortium to build a confirmation test-plant for a new Japanese gas-to-liquids (JGTL) process. Construction on the 500-bbl/d facility, located at Niigata, Japan,…
Traditionally, the cogeneration of steam and electricity has been restricted to plants that generate superheated steam, making the recovery of energy losses from saturated steam impossible for many industrial sites ranging from distilleries to pharmaceutical plants and pulp-and-paper mills. At…
Last month, UC Rusal (Moscow, Russia; edlinks.chemengonline.com/ 6901-542) signed an agreement with the government of Russia's Saratov region for the construction of a major energy and metals complex, which includes the expansion of the Balakovsky nuclear-power plant. UC Rusal will…
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…
BASF Corp. (Florham Park, N.J.; edlinks.chemengonline.com/6899-536) and CogniTek Management Systems, Inc. (Northfield, Ill.; edlinks.chemengonline.com/6899-537) have signed a cooperative agreement to study the combined use of supercritical (SC) CO2 and ionic liquids (Ils) as a potentially efficient way to utilize low-temperature…
Researchers from the fluid-dynamics laboratories at CSIRO Manufacturing and Materials Technology (Melbourne, Australia; edlinks.chemengonline.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…
This system, which has multiple reactors and uses microwaves for heating, has been developed by professor Yuji Wada at the Graduate School of Science and Engineering, Tokyo Institute of Technology (edlinks.chemengonline.com/6898-543), in cooperation with Shikoku Instrument Co. (Takamatsu; edlinks.chemengonline.com/6898-544) and…
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…
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…
