Simulation and Optimization of Absorption Column of the Dual-Pressure Nitric Acid Production Process

Article Preview

Abstract:

Simulation of the absorption column was studied. A new mathematic model was developed and tested against the actual operation data. From this, the accuracy of the model was proved. The pressure, temperature and gas composition on absorption effect was discussed. And from the point of the practical production, more optimized operating conditions of the nitric acid absorption tower were showed. It makes the dilute acid concentration increase by 3 percent and the exhaust emission of NOx decrease by 45ppm.
