Abstract: Computer-implemented methods, computer program products and computer systems for facilitating a customer's online purchase of school supplies listed on one or more generic teacher school supply lists using an online store's website. The computer-implemented methods, computer program products and computer systems provide a user access to select one or more teacher's generic school supply lists from a plethora of generic school supply lists. Online retailer's products are indexed against items on the teacher's generic school supply list so that after user selection of a particular teacher's generic school list, the user is provided with one or more graphical user interfaces identifying all matching items of the retailer for a given teacher's school supply list. The customer is presented with one or more graphical user interfaces that allow the user to purchase the matching items. UPC codes can be used to index a retailer's product to a corresponding item on a teacher's generic school supply list.

Abstract: A process is disclosed for removing nitrous components from a raw liquid nitric acid stream to produce a bleached nitric acid product (55). The raw liquid nitric acid stream (37) is from an absorber (19) of a nitric acid process. The process comprises contacting the raw nitric acid liquid stream with an oxidising gas (12) in a bleaching stage (52). At least some of the gas effluent (12c) from the bleaching stage enters (12d) a combustion stage (15) of the nitric acid process. The oxidising gas (12) entering the bleaching stage (52) may comprise at least about one-third of an oxidising gas feed (12) to the nitric acid process. At least about one-tenth of the bleaching stage gas effluent (12c) may enter (12d) the combustion stage (15).

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.

Abstract: A process for producing nitric acid is disclosed in which a gaseous oxidizer feed composed at least substantially of ammonia, steam and an oxidizing gas is exposed to conditions whereby the ammonia is oxidized to produce a reaction mixture including nitrogen monoxide and water vapor. The reaction mixture is then cooled in a heat exchanger whereby: a) the nitrogen monoxide is oxidized and the water vapor is caused to condense, b) the products of the nitrogen monoxide oxidation react with and are absorbed by the condensed water, and c) substantially all of the nitrogen monoxide in the reaction mixture is converted to nitric acid. Also disclosed is a nitric acid solution when produced by the disclosed process.

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.
