What are the reasons for the high temperature at the top of the absorption tower?
Thread Content
I am using copper smelting flue gas with two stages of conversion and two absorption steps to produce acid, in two separate systems; there is a demister at the top of each absorption tower. At present, for one unit in the series, the temperature at the top of the absorber is high (i.e., the temperature at the outlet of the demister is high), being 10–20°C above the normal upper limit; all other temperatures are normal ； The temperature of the other series is normal, and the top temperature of the tower is also normal (5-10°C lower than the upper limit of the normal range). What are the reasons for the high temperature at the top of a absorption tower?
One is the temperature of the gas entering the tower; second, the temperature of the acid in the circulation system and the amount of acid fed into the tower; third, the packing inside the tower, and whether there is any deviation or short-circuiting in the flow of flue gas
The hot air flow is high, and there may be less absorbent liquid with a lower flow rate.
Thank you! The outlet temperature of my series of demisters is high, but the inlet temperature of the demisters is normal. What could be the reason?

The temperature at the top of the absorption tower has little to do with the temperature at the outlet of the electrostatic precipitator, unless there is an excessive amount of acid mist
Did the uncaptured acid mist condense at the top of the tower?
The amount of circulating acid is low, or the acid distributor is damaged causing misdirection of the flow
Thank you! It means that the absorption of SO3 is insufficient, right?
