ADVANTAGES AND BENEFITS

  • Improvement of heat transfer and intensification of bubble evaporation

  • Gentle removal of existing deposits and minimization of new formation

  • Protection of the entire water/steam system against general and local corrosion (stress corrosion cracking)

  • Reduction of erosive corrosion and drop impact erosion

  • Conservation of the plants out of the operational regime

  • Protection against standstill corrosion when filled, partially emptied and emptied

  • economical and ecological due to the low use of chemicals

PRODUCT FEATURES

ODACON® was specially developed for the treatment of water and water-steam circuits. The products are aqueous emulsions of saturated alkylamines with a chain length >C15. No additives are required to produce the emulsions, 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 vapor volatility of the active ingredient, the entire system including steam and condensate lines and steam consumers is protected.

According to the FDA Code of Federal Regulations, Title 21, Volume 3, § 173.310, direct contact with steam containing ODACON® is permitted in the food and pharmaceuticals industry up to 3 mg/l and according to Volume 4, § 200.11 for sterilization purposes of surgical instruments up to 2 .4 mg/l permitted. The ODACON® products are not hazardous substances as defined by current legislation. They are harmless for indirect discharge via sewage treatment plants into receiving waters. It is minimally dissolved in the waste water, the excess can be filtered off.

HOW IT WORKS

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 nanometers thin, diffusion-tight protective layer is formed, which is resistant to the ingredients normally found in water and steam cycles. The formation of a uniform 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 pollutants 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 vapor 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 behavior in the wet steam area is optimized. In addition, the active ingredient accumulates on the surface of water droplets and increases the pH value directly on the droplet or component surface.
