Mono, medium pressure plant (4, 5bar) with 3 burners and
an absorption system of 4 packed columns
Equiped with a steam driven Parson compressor train with
a Curtiswheel and a DeNOx installation to reduce NOx
emissions to 200ppm
Steam system operates at a pressure of 20bar and is integrated
with site steam production grid
Summary plant process
Air is compressed to 3.8 bar. The compressed air is split into two parts, 80% (primary air) is used for ammonia burning, 20 % (secondary air) is cooled and applied for degassing of produced acid
Liquid ammonia is vaporized into the gas phase, preheated and mixed with primary air in a 10 – 10.5 % proportion mixture.
The mixture is burned on a platinum/rhodium bed at 880° C to nitric oxides. Reaction heat is converted into 20 bar steam to heat the end gas. The nitric oxide gases are cooled.
The nitric oxide gases are converted in the absorption towers into 54% nitric acid. The nitric acid is pumped into an acid degassing installation.
Acid degassing and storage
The nitric acid is degassed by reverse current of secondary air
The final product is stored in tanks.
Machines are sold on 'as is where is' basis. It is the responsibility of the purchaser to ensure the machine is fit for purpose.
