ODACON® was specially developed for the treatment of water systems and high pressure (typically>50 Bar) water-steam circuits. The products are aqueous emulsions of saturated alkylamines with a chain length >C15. No additives are required to produce the emulsion, so it is a pure product. For this reason, ODACON® is also approved for use in nuclear facilities. Since ODACON® does not contain any admixtures of phosphate, hydrazine or similar products, it does not add salt to the boiler or circuit water. Due to the vapour volatility of the active ingredient, the entire system including steam and condensate lines and steam consumers are protected.
The surface-active substance octadecylamine contained in the emulsion increases the pH value in the phase boundaries of the systems, has a dispersing effect and lowers the surface tension of the water.
By adsorption of the active substance molecules on the material surface, a few nanometres thin, diffusion-tight protective layer is formed. This layer is resistant to the impurities, that are normally present in the water and steam cycle. The formation of a uniform electro-potential level also protects different materials from electrochemical corrosion. When the system is taken out of operation, the protective layer is retained and forms a diffusion-inhibiting, hydrophobic surface. During adsorption, chlorides or similar impurities are displaced from the surface and from crevices. The released ions are bound and can be discharged with the blowdown water. By lowering the surface tension of the water, the vapour bubbles are reduced during evaporation and the bubble frequency is increased. On the other hand, the diameter of the water droplets is reduced during condensation and thus their flow behaviour in the wet steam area is optimised. In addition, the active ingredient accumulates on the surface of water droplets and increases the pH value directly on the droplet or component surface.
