FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing ammonium nitrate. A method of producing ammonium nitrate includes exposing gaseous raw material to oxidation apparatus conditions, said material substantially consisting of at least ammonia, steam and an oxidising gas, as a result of which ammonia is oxidised to obtain a reaction mixture which includes nitrogen monoxide and steam, followed by cooling the reaction mixture in a heat exchanger, as a result of which nitrogen monoxide is oxidised and the steam is condensed; the nitrogen monoxide oxidation products react with the condensed water and absorbed by said water; and substantially all the nitrogen monoxide in the reaction mixture is converted is converted to nitric acid, followed by reacting the nitric acid stream with an ammonia stream to form ammonium nitrate.
EFFECT: invention enables to obtain ammonium nitrate without using an absorption column.
