摘要： A process for producing ammonium nitrate is disclosed, which process comprises exposing a gaseous oxidiser feed composed at least substantially of ammonia, steam and an oxidising gas to conditions whereby the ammonia is oxidised to produce a reaction mixture including nitrogen monoxide and water vapour. The reaction mixture is cooled in a heat exchanger whereby the nitrogen monoxide is oxidised, the water vapour is condensed and the products of the nitrogen monoxide oxidation react with and are absorbed by the condensed water to form a nitric acid stream, with substantially all of the nitrogen monoxide in the reaction mixture being converted to nitric acid. The nitric acid stream is reacted with a stream of ammonia to form the ammonium nitrate. Also disclosed is ammonium nitrate per se (in any of its various possible forms) when produced by the disclosed process.
