Reason for the high carbon dioxide content in the double alkali reaction AⅠ

Generally, high AI CO2 levels are caused by poor carbonation reactions, which result in inadequate production of alkaline solution for ammonia fixation. Additionally, poor carbonation can also be due to changes in the composition of the mother liquor fed into the tower. Therefore, it’s not always possible to detect issues related to mother liquor circulation; various factors such as salt addition during crystallization, the temperature during carbonation, the process of extracting products, and the control of ammonia absorption levels all need to meet specified requirements, with continuous monitoring of these factors being necessary to ensure that CO2 levels remain within acceptable limits. If AI CO2 levels become too high, it is essential to adjust the relevant parameters or reduce the amount of input material promptly; otherwise, over time this can lead to a vicious cycle that causes significant fluctuations in the system.
