If carbon steel is used for the concentrated sulfuric acid storage tank, will acid mist form in the gas space at the top? ?
Thread Content
I would like to ask: since carbon steel is used for sulfuric acid storage tanks, could water vapor in the gas space at the top lead to the formation of acid mist that corrodes the equipment? How do people prevent corrosion at the top of sulfuric acid storage tanks? ? ? Including vapor vent pipes
Take a look at the preparation and storage of concentrated sulfuric acid; it might be useful
If the acid tank is not full, and if it is not directly exposed to air, there will be no water vapor in the headspace, nor any additional corrosion, so no special treatment is required. It’s the pressure balance tube that needs to be properly dealt with.
Sulfuric acid has such strong water-absorbing properties – how could there be any water vapor at all?:D

As long as nicotinic acid is not released, no acid mist will form without the evaporation of sulfur trioxide gas
Installing a breather valve on the air control system solves the problem
Can I make a bend at the top to connect it to the atmosphere?
The tops of the tanks used for storing concentrated sulfuric acid that I’ve built are equipped with desiccators. At the top of these desiccators there is a 180-degree elbow; when the particles inside the desiccator become too large, they need to be replaced. Concentrated sulfuric acid is stored in tanks made of pure carbon steel, while dilute sulfuric acid is stored in tanks lined with plastic
It mainly depends on whether the feed can enter the diluent
