H2SO4 Corrosion Stainless Steels

[vitoralmeida]

We were enquired on a new reactor to handle the following mix:
14.000 lt caju oil + 500 lt of H2SO4 (diluted 50%).
The oil goes first into the tank and then the acid is mixed.
The working temperature is 220ºC at 4 Bar.

Can anyone suggest a propper SS to use in the construction of the reactor? Considering the temperature is there a propper SS at all?

Thank you!

How much water is there?
What are the reaction products?
I presume that there is excess acid, how much?

Corrosion never sleeps, but it can be managed.

Hello, thank you.
The dat we received from the client is that the mix will be 14 000 lt of cashew nut oill + 500 lt of H2SO4 (diluted 50%). We don't know the exact percentage of water in the oil.
