Nitric acid production process

The process control in the process of nitric acid production

Also known as nitric acid (HNO3)Nitric acidorAmmonia waterAs fertilizer, used in the production of ammonium nitrate of the materials.Nitrate was the key to production of adipic acid and terephthalic acid composition.Other applications include explosive, leaching mining and stainless steel pickling.According to different, the final concentration needed for nitric acid production process may contain one or two process.

Usually by ammonia nitrate via high temperature catalytic oxidation.This process involves three main steps: ammonia oxidation, oxidation and the absorption of nitric oxide.

The most common type of catalyst by about 10% 90% of platinum and rhodium (mass percent).Catalyst in wire forming and insert in the converter.To continue, the exothermic reaction about 93-98% of its nitric oxide.Then, has been cooled to a specific temperature and pressure reach regulation.The reaction is highly dependent on temperature and pressure.

After cooling, nitrogen dioxide/four nitrogen oxide mixture into the absorption tower.After absorption, acid concentration usually between 55-65% (mass percent).

Visa K - PATENTS^®Online refractometer is used to control the absorption process and the stability of nitric acid density.
