Boiler condensate water contains carbon dioxide (from the feed water alkalinity) which is corrosive to steel. If left untreated, condensate water would have a pH of 5.0 to 6.5 which is corrosive to the steel piping in the condensate return lines and adds iron deposits to boilers.
Neutralizing amines are a common steam line treatment that can be fed in a water treatment solution along with other treatment chemicals or it can be fed directly to the steam header. When feeding the amine to the feed water system, it should be fed downstream of the deaeration equipment. The neutralizing amine is volatilized and carried out with the steam in the condensate to react with carbon dioxide. Different amines will stay with the steam (liquid–vapor distribution ratio) until it drops out of the steam and it is based on this ratio that we say whether an amine has a short run, medium run, or long run distribution.

This product’s main ingredient is phosphate which can effectively combine the Ca, Mg, and Fe within the boiler to gelatinous substance; it can prevent Calcium carbonate with Mg, Calcium sulfate with Mg and other boiler scales to be formed.
It can also prevent oxide iron from accumulating and causing oxidation. and these can be released by regularly discharging boiler water. Another main ingredient is PH agent; it can control the PH level and suppress the dissolution of iron to prevent silicate salt scale to be formed and avoid caustic embrittlement.
It is suitable in hot water and can effectively remove dissolved oxygen.

If deposits are allowed to form on heat exchangers, the loss of efficiency can be directly related to extra fuel consumption. A 1 mm deposit is approximately equivalent to a 10% efficiency loss, a 3 mm deposit can reduce efficiency by up to 50%. The normal ignition temperature of soot is around 600°C. This means that it is burned only in the hottest parts of the boiler or diesel exhaust systems. Due to the catalytic action of Soot Remover, the ignition temperature of the soot/deposit is reduced to less than 280°C. The carbon deposits are thus ignited, leaving an easily removed ash.
The use of Soot Remover not only provides greater fuel efficiency, but also prevents acid formation in areas where severe corrosion could result in expensive damage, i.e. heat exchangers, superheaters, economisers, exhaust paths/stacks.
