Environmental and Technical Aspects of the Utilization of SRC, AFBC, and Low-Btu Coal Gasification in Industrial Processes

摘要

The decreasing availability of oil and natural gas has stimulated the search for industrial coal-utilization methods that are alternatives to conventional coal combustion. Three such alternative methods discussed in this report are solvent refined coal (SRC-I), atmospheric fluidized bed combustion (AFBC), and low-Btu coal gasification. Clean low-Btu gas and SRC may have several nonboiler industrial applications. In contrast to conventional coal combustion, use of these fuels has the potential for reduced environmental impact at the industrial plant site, although the impact of coal mining and transportation will be higher. The impact of coal gasification and liquefaction on occupational health and safety will cause the greatest concern. (ERA citation 04:045887)
