Prospective environmental performance of utility plants using low Btu gas produced via the KILNGAS process

The KILNGAS process can meet current NSPS requirements, and potentially can exceed them by significant margins. In Clean Air Act nonattainment areas or in foreign countries having more stringent emission requirements, KILNGAS system LBG represents an approach not readily satisfied by many other technologies. More specifically: it is relatively easy to add process equipment enabling removal of additional sulfur compounds to reduce potential SO/sub 2/ emissions by 98+ percent; fuel-bound nitrogen removal (in the form of ammonia) in combination of lower flame temperatures for LBG combustion relative to other fuels reduces potential NO/sub x/ formation. It appears that design of any LBG combustion equipment for meeting potentially more stringent NO/sub x/ limits would be easier than with conventional fuels including medium-Btu gas; particulate emissions, requirements for which are based on combustion limits, are potentially below current NSPS requirements, on the order of one-tenth.
