Helamin - Wikipedia, the free encyclopedia

Helamin

From Wikipedia, the free encyclopedia

Helamin is a water treatment chemical. The name is a registered trademark of Filtro, SA, Geneva, Switzerland[1]. Helamine is one of the commercial fouling, corrosion and incrustation inhibitors. It uses the characteristics of aliphatic 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 and fouling on the water-side walls in steam boilers and piping systems. It happens because Helamine has an affinity to metal and oxide surfaces. Crystals which do form in the presence of Helamine are isolated, so that they cannot group themselves any longer. Thus deposit consolidation is inhibited. Already existing oxide 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 and pressure employed in the modern sub-critical -water power-plant boilers. Helamin treatment can be successfully employed in steam generators, warm and hot water piping systems, superheaters, as well as cooling circuits to mitigate some of the difficult problems of the corrosion and fouling.
