Sulfuric Acid Pipework Material 1

[jph90]

Hi All,

Looking for some guidance on the best materials to use for Sulfuric Acid pipework transfer, and diluted but low pH mixture. There are two operating conditions:

1) 98% Sulfuric Acid injection to a tank - ambient temp but tank is heated w/steam to approx 90-100 deg C therefore can consider some heat transfer, particularly at the connection point/flange
2) Highly acidic (pH 2) Acid Water and Acid Oil pipelines (following injection of H2S04) at 100 deg C, roughly 5% dilution of sulfuric acid in the mix.

Pipeline velocities <2m/s

For background info the application is an oil soapstock splitting plant

Appreciate any help

And don't do anything until you read it.

It would be helpful if you could determine to what extent heat transfer will occur? I assume it is ambient initially?

How much cost consideration is going into this?
