chemical resistance FRP tank for Acids

Thread by Syed Arsalan Afsar on 19 Apr 2010 at 09:58:24 
Dear sir,

what is the best resin for FRP tank containing following media

1-nitric acid (50%-60%) at ambient temperature.
2-sulphuric acid 70% at 120 degree Centigrate.

your early response will be highly appreciated .

    Dear Syed Arsalan Afsar,

    Thanks for your thread.

    - What is the required lifetime for the composite (10, 20, 50, 100 years)?
    - Are there any regulations or resistriction for acid emissions from the tank (by long term permeation through the tank wall)?
    - I suppose you are looking for a matrix with glass reinforcements?
    - Is there a global indication of the dimensions of the tank?

    Looking forward to hearing from you.

    Kind Regards,

        Could you clarify a little more on the second media: where do you get 70% sulphuric acid at 120 degrees Celsius? The temperature in combination with the high concentration is unusual for FRP materials.

        For the first media an option could be the best grades of Derakane Vinyl Ester Epoxy Resins, but even here a more rigorous analysis is required.
