Summary of Gas Stream Control Technology for Major Pollutants in Raw Industrial Fuel Gas

摘要

The report summarizes coal gasification and clean-up technology with emphasis on methods of producing a clean industrial fuel gas as defined by agreement for study purposes. The coal-derived industrial fuel discussed produces no more than 0.5 lb of SO2, 0.4 lb of NOx, and 0.1 lb of particulates per million Btu of fuel gas. In general, existing state-of-the-art control technology will allow these emission guidelines to be met, although the end use for the fuel gas will strongly influence the choice of the pollution control technology that is used. Many but not all important factors pertinent to control technology application were considered. Costs are an example of important factors which were not evaluated because the objective was to first determine appropriate technology that could be applied. Emissions other than the three major pollutants indicated were given only cursory treatment. Nevertheless, a general overall background of control technology for industrial fuel gas has been covered.
