摘要

The report describes a study of air pollutants emitted by the ammonium nitrate industry. The potential environmental effect of the source was evaluated. Representative processes and an average plant were defined for the purpose of establishing a base on which to determine the emissions and severity of the source. The industry produces 39% of its original solution capacity as ammonium nitrate solutions and 61% as solids,of which 92% are formed by prilling. The remaining 8% are formed by granulation or graining. Primary emissions from ammonium nitrate plants are particulates and ammonia. Processes releasing the greatest amount of emissions are the neutralizer (particulates and ammonia) and the prill tower (particulates). Emission factors were found to be highly dependent on individual plant operation.
