What happens if the inlet temperature of a absorption tower is above 300 degrees Celsius?

What happens if the inlet temperature of a absorption tower is above 300 degrees Celsius? Will there be a lot of acid mist at the tower outlet? I once saw an example where the temperature at the top of the tower was relatively low (around 30 degrees Celsius); despite the use of a mesh filter at the tower top, the sample taken from there was clean. The acid mist in the first absorption tower is not significant, but it is quite high in the second absorption tower of this unit.
I’ve seen it; there’s no acid mist, but the amount of acid in circulation needs to be higher
The temperature of the acid used in the upper tower should not be too low; 30 degrees Celsius is too low, and acid mist will definitely form!
It seems he was saying that the temperature inside the tower is extremely high, the temperature of the acid at the top of the tower is extremely low, the demister is underpowered, and the level of acid mist is also very low

Such extreme situations are now rare. In accordance with the design style of the former Soviet Union, the empty tower gas velocity is 0.8; the height of the main packing is 5–6 meters. The amount of acid mist above the capture packing inside the tower is likely to be lower.
Does this filler have any impact?
The tower is designed in the style of the former Soviet Union; it features a low gas velocity in the empty tower section, as well as a relatively large packing height
There is no economizer before the absorption tower; the temperature of the gas entering the tower reaches 300 degrees, and operation is satisfactory, with no acid mist or condensed acid.
This situation can occur when water or steam from the boiler system leaks into the sulfuric acid system
In this case, no boiler or steam equipment is installed in the acid production unit.
