I would like to ask the experts: what is the relationship between the desalination water volume and the air intake volume in a nitric acid absorption tower? How to increase the acid concentration after the nitric acid absorption tower?

The relationship between the amount of water used for desalination and the volume of air fed into the nitric acid absorption tower is such that as the volume of air increases, it is generally necessary to increase the amount of water used for desalination in order to maintain appropriate humidity and temperature inside the tower, thus ensuring effective absorption of nitric acid. To increase the acid concentration after the nitric acid absorption tower, the following methods can be employed: 1. Increase the supply of nitrogen oxides (NOx) and the preheating temperature of the gas to ensure a more complete reaction ; 2. Optimize the gas-liquid contact efficiency within the absorption tower, for example by optimizing the filler design or using a more efficient absorption tower structure ; 3. Control the humidity of the air entering the absorption tower, and appropriately reduce the moisture content in the incoming air ; 4. Adjust the operating pressure and temperature to find the optimal operating conditions. .
