Fertilizers industry



The fertilizers industry makes use of nitric acid and nitrous vapors absorption production units, which are very complex production processes. For example, the absorption of nitrous vapors that reduces the emissions from nitric acid manufacturing processes is a complex process to control and furthermore to model or simulate.




Nitric acid and ammonia

Whether considering the absorption of nitrous vapors to limit emissions and/or the production of nitric acid, the phenomena involved are complex to understand and to master. Their modeling requires very special skills and expertise.

For many years, experts from ProSim are working closely with manufacturers in this sector to enable them to increase their production efficiency, increase profitability, and be able to comply with new regulations.

The software ProSimPlus HNO3 is a software dedicated to nitric acid production units and the oxidation-absorption of nitrous gases and has no equivalent on the market. ProSimPlus is a software which is very efficient for the simulation of units such as the production of ammonia.
