    摘要： A process for producing nitric acid is disclosed in which a gaseous oxidiser feed composed at least substantially of ammonia, steam and an oxidising gas is exposed to conditions whereby the ammonia is oxidised to produce a reaction mixture including nitrogen monoxide and water vapour. The reaction mixture is then cooled in a heat exchanger whereby: a) the nitrogen monoxide is oxidised and the water vapour 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.

    摘要： Systems and methods of producing chemical compounds are disclosed. An example chemical production system includes an intake chamber having intake ports for entry of a gas mixture. An igniter ignites the gas mixture in the intake chamber. A nozzle restricts exit of the ignited gas mixture from the intake chamber. An expansion chamber cools the ignited gas with a cooling agent. The expansion chamber has an exhaust where the cooled gas exits the expansion chamber. A chemical compound product is formed in the expansion chamber.

    摘要： Methods and systems for treating a gas stream comprising NOx are disclosed. In one embodiment of the method, the gas stream comprising NOx is reacted with ozone to form oxidation products including nitrogen sesquioxide and nitrogen pentoxide. At least a portion of the nitrogen sesquioxide and nitrogen pentoxide is reacted with water to form nitric acid, and a solubilized form of the nitric acid is collected and may be reused or otherwise utilized. Systems for conducting the method also are disclosed.

    摘要： Ammonia in a gas stream comprising oxygen and nitrogen may be effectively completely oxidized to a mixture of NO and NO2 for further processing to nitric acid. The gas stream is flowed over fine particles of La1-xSrxCoO3 and/or La1-xSrxMnO3, and/or La1-xSrxFeO3 where x=about 0.1, 0.2, or 0.3. The particles are supported as catalyst layers on gas stream-contacting surfaces of a flow-through catalyzed oxidation reactor. These relatively inexpensive perovskite-type materials may be used to promote oxidation of ammonia at temperatures below about 450° C. to about 500° C. to selectively produce a mixture of NO and NO2. This mixture is suitable for further oxidation to NO2 for adsorption into water to make nitric acid.
