Oxygen pitting corrosion and general acid corrosion have historically been problems in food processing facilities. This is true where the steam contacts the food being produced due to the limitations on the condensate corrosion inhibitor dose imposed by the FDA.

This paper presents performance data regarding a novel condensate corrosion inhibitor that provides improved corrosion protection versus several existing FDA-approved commercial filming inhibitors. This new inhibitor is designed to be fed to the steam phase to protect iron and copper alloys in the steam condensate system against the damaging effects of carbonic acid and dissolved oxygen corrosion.

Efficacy data derived from both laboratory experiments and field applications will be presented.
