Process Flow Diagram Nitric Acid Plant. The process involves t he catalytic oxidation of ammonia by air oxygen yielding. A typical nitric acid plant flow diagram is shown in fig.
About 70 percent of the nitric acid produced is consumed as an intermediate in the manufacture of. Inorganic chemicals manufacturing 1 10 introduction the purpose of all emission estimation technique eet manuals in this series is to assist. With a total capacity of 11 million tons of hno 3 per year.
After the process gases have been cooled in a series of heat exchangers boilers and steam super heaters they pass into an oxidising absorption tower where with air and water.
Ideas about process flow diagram nitric acid plant. The plants range in size from 6000 to 700000 tons per year. 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. After the process gases have been cooled in a series of heat exchangers boilers and steam super heaters they pass into an oxidising absorption tower where with air and water.
