The retorting of oil shale yields several undesirable pollutants. The nitrogen in the shale and the reducing conditions under which the retorting is carried out results in the formation of sizeable amounts of ammonia in the gas stream. If not removed, the ammonia will make a significant contribution to the NOx emissions after the gas is burned. The projected NOx emissions from five selected oil shale developers were modeled using the VALLEY air dispersion model and found that the levels of NOx were increased near the plant sites but dropped off to just above baseline at a distance of 6 km. Additional projections of NOx impact on the ambient air impact were also made as a result of modifying the combustion conditions and use of Selective Catalytic Reduction control technology. Both of the additional control technology options corresponded to tighter air pollution regulations. It was concluded that oxide of nitrogen emissions would not be a significant air pollution problem in the development of the oil shale industry.
