Limitations of conventional treatment & Necessity to Introduce Indiamin Chemicals
How INDIAMIN works
INDIAMIN is essentially formulation consisting of polycarboxylates and surface-active fatty alkyl polyamines in combination with other amines of varying volatility.
The use of INDIAMIN to treat water and steam carrying systems, such as water/steam and heating circuits, has many advantages over conventional conditioning which often requires several substances to be added at various locations and needs regular monitoring.
In the boiler water of steam generators the polyelectrolytes have a synergetic effect. The polycarboxylate causes at every temperature an alkalization because of hydrolysis. As a polyelectrolyte it has greater affinity to bivalent cations (e.g. Fe2+ or Ca2+), like a weak acidic ion exchanger. Hence, quite stables calcium or iron salts are formed which can be removed by blow down. Silica present both in soluble and insoluble form is dealt by breaking the silica chain to form complexes that neither adhere to the metal surface nor get carried over to steam phase thereby easily removed by blow down. At the stoechiometric limits any residual hardness is kept in solution. Any additional contaminants are sequestered, suspended and dispersed,
i.e. prevented from crystallizing and therefore forming scale, or any other deposits. The polyamine has a greater propensity to be adsorbed at the interfaces. In addition to the corrosion-protecting effect of the membrane, it also prevents calcium carbonate crystals from growing on the material surface, especially in the area of the heat transfer. Corrosion products which are transported into the boiler are also prevented from accumulating and any existing deposited can be gently removed. If used in stream generators, pre heated networks, super heaters, turbines and cooling systems, INDIAMIN is an efficient, economical and ecological solution to the difficult problem of corrosion and scaling.
The INDIAMIN range of conditioners provide additional safety due to preventive surface protection the key to successful and economic operation of your systems.
Function:
INDIAMIN contains as amine which is absorbed to the boiler or pipe surface and forms a membrane; in this way the surface is protected against corrosion while deposits are prevented to a large extent.
INDIAMIN application
An INDIAMIN solution is dosed into the feed water and/or to Boiler Drum. A higher initial concentration is necessary in order to build up the protective membrane.
INDIAMIN contributes to build – up a protective magnetite layer. Indeed, it has been proved that
INDIAMIN improves the structure of the magnetite layer and increases the protective effect. Thermal and oxidative decomposition haven’t been found to form toxic products.
