Food grade corrosion inhibitors

[brimmer]

Wondreing if anyone can provide some information into food grade corrosion inhibitors. In this case, a 16" hydrocarbon pipeline will be converted to transport brine, the brine will be sold on the other end to food manufacturing industry as the salt is pure. There are many inhibitors that work for brine used in oil/gas industry, but we would need something that is food grade or safe for human consumption. There are many inhibitors used in potable water distribution which are safe, but would they stand up to brine? I think we need a filming inhibitor to lay on the walls and perhaps an oxygen scavenger. Any info/ideas or companies which might have such products would be much appreciated. Thank you.

I don't know how you will decontaminate a hydrocarbon pipeline but sodium metasilicate is probably a good candidate for corrosion inhibitor.
