- Helamin
Helamin is a water treatment chemical. The name is a registered trademark of Filtro, SA, Geneva, Switzerland [A.Bursik, "Polyamine/Amine Treatment - A Reasonable Alternative for Conditioning High Pressure Cycles with Drum Boilers", Power Plant Chemistry, 2004,(6)9. http://www.ppchem.net/free/ppchem-free-9-2004-2.pdf] . Helamine is one of the commercial
fouling ,corrosion andincrustation inhibitors. It uses the characteristics ofaliphatic polyamine . In contrast to the conventional method of the water treatment, its action is based on a preventive protection of the surfaces. Helamin forms a firmly adhering protective film, which prevents corrosion andfouling on the water-side walls in steamboiler s and piping systems. It happens because Helamine has an affinity to metal and oxide surfaces.Crystal s which do form in the presence of Helamine are isolated, so that they cannot group themselves any longer. Thus deposit consolidation is inhibited. Already existingoxide surface deposits are gradually removed. Boiler develops a fine, liquid mud, which does not tend to accumulate in the boiler.Helamin does not significantly decompose even at high
temperature andpressure employed in the modern sub-critical -water power-plant boilers. Helamin treatment can be successfully employed insteam generator s, warm and hot water piping systems,superheater s, as well as cooling circuits to mitigate some of the difficult problems of the corrosion and fouling.References
