Reasons for positive pressure in the synthetic exhaust gas absorption tower and how to address it

This post was last edited by swl on 2017-4-17 at 13:36. The original poster is asking about the absorption tower for hydrogen chloride synthesis exhaust gases, right? The issue of \"positive pressure in the hydrogen chloride synthesis exhaust gas absorption tower\" is mainly caused by an \"imbalance between inflow and outflow.\" There are three possible explanations: 1. The amount of hydrogen chloride entering the tower is normal, but the absorption capacity of the absorption tower has decreased; as a result, the inflow remains unchanged while the outflow decreases, leading to positive pressure ； (Associated with the factors that reduce the absorption capacity of the absorption tower: there are issues such as the amount of water used for absorption, problems with the distribution of water (or gas), and damaged packing.) 2. When the absorption capacity of the absorption tower is normal, but the amount of hydrogen chloride entering the tower exceeds the specified flow rate, this leads to an increase in absorption while the outflow remains unchanged, resulting in a positive pressure ； 3. Both of the above conditions are present simultaneously ；
