I have a question regarding the corrosion caused by dilute sulfuric acid!

It is a packed tower at atmospheric pressure, using 2.5% dilute sulfuric acid as the medium; the maximum temperature of the inlet fluid is 50°C, and the inlet distributor is of the nozzle type. I would like to ask whether dilute sulfuric acid sprayed from the nozzle, when it hits the tower wall, results in a high corrosion rate of that wall (I’m wondering if the fast flow rate of dilute sulfuric acid emitted by the nozzle results in a high corrosion rate?) ).
It will definitely be high. Medium flow rate exacerbates corrosion. It is recommended to install baffles.
If the nozzle sprays directly onto the tower wall, it will inevitably accelerate the flow of the medium and speed up corrosion; therefore, protection against erosion corrosion should be considered.
