  • Volatile Corrosion Inhibitors and Boiler Water Additives

    The volatility of the boiler water amines, specifically their ability to steam distill, simply allows them to be intro- duced into the boiler and transferred through the system to the area which re- quires corrosion protection, i.e., the area where the steam condenses to give a liquid-metal interface. This report is divided into four major

    This alkalinization is performed to control corrosion of metal components. ETA (or sometimes a similar organic amine; e.g., morpholine) is selected because it does not accumulate in steam generators (boilers) and crevices due to its volatility, but rather distributes relatively uniformly throughout the entire steam cycle. In such application, ETA is a key ingredient of so-called "all-volatile treatment" of water …
