An evaluation of control needs for the nitrogen fertilizer industry. Final report March 1978-July 1979

Technical Report ·
OSTI ID:5502899
;
The report gives results of an evaluation of pollution control needs for the nitrogen fertilizer industry. It includes descriptions of ammonia, ammonium nitrate, and urea manufacturing processes and evaluations of existing processes, pollution control techniques, and emissions. It also evaluates existing and potential pollution conrol techniques, processes, and alternative feedstocks as they apply to manufacturing ammonia, ammonium nitrate, and urea for additional pollution control and emission reduction. Air emission and water effluent controls were examined for each process. Source severity factors were used to evaluate the environmental significance of emission sources. The most significant emission problems associated with the industry are (1) oxides of nitrogen from the addition of purge gas and overhead to primary reformer firing in ammonia synthesis, and (2) particulates from prilling towers in ammonium nitrate and urea production. Further work is needed to develop adequate control techniques for these pollutant sources. All other pollutant sources for this industry can be adequately controlled by existing technology.
