sulfuric acid tanks
(OP)
Hello,
I am not too sure about what is best. For a 94% sulfuric acid storage (5m3), room temperature , what is best in terms of corrosion?
Carbon steel or stainlass? I know that carbon steel should be OK, but some people insist on stainless
I also have a second, related question. the breathing of the tank. Should it go through a dryer, to avoid any moisture in, or can we spare it. (European countries, air at 20°C)
Thank you in advance

RE: sulfuric acid tanks
At your operating conditions, room temperature, and acid concentration of 94% you can use carbon steel. There is a NACE Standard, NACE SP0294-2006, that specify materials for sulphuric acid tank.
NACE suggest a min of 3.2 mm of CA and a typical of 6.4 mm for conc between 88 to 99 %.
Ingress of moisture can cause severe corrosion at the liquid-air interface due to acid dilution. In the NACE standard you can find also requirement for Vent and measures to avoid moisture related problems.
