The positive properties of filming amines with respect to corrosion protection in water-steam cycles have been known for many decades. The application of film forming amines in industrial and utility steam-water cycles is constantly increasing. However, there are still no internationally accepted recommendations or guidlines covering the application of film forming and neutralizing amine blends. In this paper, the positive long-term field experience with fil, forming amines is summarized and an attempt is made to develop a first draft of guidance for use of alkalizing and film forming amines with all-volatile treatment. It is hoped that the proposed guidance will serve as a first blueprint for further discussion.
