Gas-liquid temperature relationship in the absorption tower
Thread Content
I would like to ask fellow industry professionals: In our plant’s absorption tower for producing 120,000 tons of sulfuric acid, the temperature of the acid entering the tower is 76 degrees, while the temperature of the acid exiting the tower is 72 degrees. Is this normal? What is the relationship between these two temperatures? :handshake
In production, the degree of uniform acid separation is determined by the difference between the acid temperature at the top of the tower and the temperature of the flue gas exiting the tower. If it is a tubular acid separator, 4 degrees is acceptable; but for a trough-type acid separator, 4 degrees is too high.

In the case of an absorption tower, the temperature of the flue gas entering the tower basically cannot be lower than 70 degrees; at the exit of the absorption tower, the temperature of the flue gas will definitely be a few degrees higher than the temperature of the acid entering the tower – it cannot drop. It’s possible that the gauge is inaccurate or there is an issue with the temperature measurement point. In the case of a drying tower, this possibility is much greater, in my opinion!
The acid temperature at the inlet of the absorption tower is 76 degrees, while the temperature at the outlet is 72 degrees – this is not normal. What was said above is correct; it can only be said that the system is not functioning properly. Under normal conditions, the temperature of the gas entering the absorption tower should be relatively high.
If it is a two-stage absorption, that is also normal; if it is a single-stage absorption, then the temperature of the gas entering the tower needs to be increased.
The acid temperature at the top of the tower is 83, while it is 103 at the bottom of the tower
The temperature points are being checked for analysis; the phenomenon described by the poster is truly abnormal.
It’s abnormal; the temperature outside the tower should be higher than the temperature of the acid entering the tower
