Hi everyone*

I would like to seek your advice related to design standards that I need to refer for the design of:

a) Nitric acid storage
b) Municipal water storage (for process: dilution of nitric acid 687 wt% to nitric acid 54 wt.%)
c) Tank level settings for NA 68* NA 54* calcium nitrate 54 wt.% solution and PAC (polyaluminum chloride solution)

Appreciate your inputs.

Regards*
