  • Patent number: 9493364
    Abstract: A process for producing ammonium nitrate is disclosed, which process comprises exposing a gaseous oxidizer feed composed at least substantially of ammonia, steam and an oxidizing gas to conditions whereby the ammonia is oxidized to produce a reaction mixture including nitrogen monoxide and water vapor. The reaction mixture is cooled in a heat exchanger whereby the nitrogen monoxide is oxidized, the water vapor 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.

  • Publication number: 20150203360
    Abstract: 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.

  • Patent number: 7549559
    Abstract: Resealable caps and tops for directional pour spout containers currently available for liquid and semi-solid products are either a spout and cap design, in which the tip is cut off to pour or squeeze out the container contents, or a non-spout, hinged top-and-bottom design, which defines a flat surface with an opening. These designs have many limitations. For example, the closure portion of a conventional spout closure can become detached, leading to production line delays, lost tips in transit, product recall at the store level, loss of shelf life and potential chocking hazards to children and pets. The non-spout hinged, top-and-bottom design does not offer the directional dispensing capabilities. This invention addresses the shortcomings of conventional caps and tops by providing a one-piece directional pour spout container cap in which the base has an upwardly directed spout and a hinged flip top cap is attached to the spout.

  • Publication number: 20050055966
    Abstract: All the basic structural components of frame construction are directly connected with one another including foundation plate, studs, floor and ceiling joists as well as rafters. The significant element of this integrated construction is a three-part composite stud easily constructed from commonly used construction lumber to form a totally unified framework which provides a much stronger, stable and desirable structure than that achieved by present construction methods.
