ABSTRACT:
A method of protecting water reservoirs or enclosures utilized in thermal energy conversion applications against corrosion during periods of shutdown by depositing a source of a vapor phase corrosion inhibitor, preferably a blend of ammonium benzoate, sodium benzoate, sodium sebacate, monoethanolammonium benzoate, benzotriazole, and cyclohexylammonium benzoate within the enclosure through the steps of packaging a vapor phase corrosion inhibitor in powder form within a container fabricated from a water-soluble film; perforating the walls of the container; depositing the perforated container within the enclosure being protected; and introducing water into the enclosure at the end of the shutdown period for simultaneously flushing the enclosure and removal of both the residual corrosion inhibitor and water-soluble container therefrom.
