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.

摘要： An apparatus (10) and process for removing acidic gases and NOx from flue gases produced by utility and industrial plants. The process and apparatus (10) convert NOx, and particularly nitric oxide, to nitrogen dioxide, which is then reacted to form a valuable byproduct. The process generally entails contacting a flue gas with a scrubbing medium (14) to absorb acidic gases from flue gas and produce an intermediate flue gas. The intermediate flue gas is then cooled to cause nitric oxide present therein to be oxidized to form nitrogen dioxide, which is then absorbed from the flue gases to produce a nitrogen dioxide-containing solution (36) and a scrubbed flue gas. The nitrogen dioxide in the nitrogen dioxide-containing solution (36) is then reacted with ammonium hydroxide to form ammonium nitrate as a valuable byproduct.

摘要： Method for obtaining fertilizing salts and derivatives of strontium, by wet process, starting from mineral material such as strontium sulphate which is reacted with ammonium carbonate in excess. This reaction is carried out continuously and with counter-current flows of reagents. This excess of ammonium carbonate used is recovered in order to recycle it in the process and to isolate the ammonium sulphate which may be treated continuously with a lime carbonate or oxide, recovering the gases evolved by the reaction and obtaining as final product lime sulphate (gypsum). In a second phase, strontium carbonate obtained is continuously reacted with nitric acid in order to obtain strontium nitrate, part of which is carbonated with gases (CO2 and NH3) producing a precipitate of strontium carbonate and a solution of ammonium nitrate.

摘要： Process for producing concentrated solutions of ammonium nitrate by neutralizing nitric acide with ammonia in a tubular reactor. When the total flow rate of reactants corresponds to a production lower than 150 kg/h/cm2 the neutralization is effected in the presence of a medium comprised of a recycling stream of the concentrated ammonium nitrate solution. When it is higher than 150 kg/h/cm2, there is no need for a recycling.

摘要： Disclosed is a method for the integrated production of two different urea products. One is an aqueous urea solution suitable for use in NOx abatement (generally indicated as Diesel Exhaust Fluid – DEF). The other is a solution used as a fertilizer, viz. Urea Ammonium Nitrate (UAN). The production of DEF and UAN are integrated as follows: ammonia recovered from the production of urea is used as a feed to the production of ammonium nitrate. At least part of an aqueous urea stream from urea production, is mixed with ammonium nitrate so as to obtain UAN.

摘要： The present invention relates to a solid, particulate, non-explosive composition comprising ammonium nitrate-based particles, in particular a fertilizer composition, of which, on the one hand, the potential misuse as a precursor for an explosive composition is limited without, on the other hand, hampering its legitimate use by farmers for food production. The solid, particulate, non- explosive composition further comprises a gelling agent which is able to form a substantially water-insoluble and non-filterable hydrogel after the solid fertilizer composition is contacted with water. The gelling agent is selected from the group of gum-based gelling agents, in particular xanthan gum-based agents and guar gum-based agents, most preferably is a xanthan gum-based agent.
