| titleOfInvention | Method and plant for producing nitric acid |
| abstract | A process and a plant for producing nitric acid involves oxidizing ammonia in the presence of catalysts to provide nitrogen monoxide-containing process gas in an oxidation reactor. The formed nitrogen monoxide may be supplied with oxygen-containing gas, and nitrogen monoxide is oxidized to provide nitrogen dioxide that is reacted with water in an absorption apparatus to give nitric acid, nitrous acid, and/or solutions of nitrates and/or nitrites. Oxidation of the nitrogen monoxide may be effected in an additional reactor positioned between the oxidation reactor and the absorption apparatus and traversed by the process gas. The oxidation of the nitrogen monoxide may be effected in an additional reactor parallel and connected to the absorption apparatus and traversed by the process gas. The disclosed processes and plants feature a high energy efficiency combined with a simple construction, and existing plants are easily upgradeable. |
