BOILER CORROSION INHIBITOR/OXYGEN SCAVENGER -ALKALINE SULPHITE BASE
BCI-S100-C is a specialized, catalyzed and concentrated boiler oxygen scavenger and corrosion inhibitor for low and medium-high pressure steam generating systems.
The dissolved 20% BCI-S100-C is nominally controlled at between 15-30mg/l in the boiler as the sodium sulphite compound in the boiler circuit water. These dosages should be
altered dependent upon dissolved oxygen content in the feed water.
mg/l dosage to boiler feed water = 5 x [ (Oxygen in Feed Water x 8) + (Residual
Required/Effective Cycles of Concentration.)]
There is a specific test method for the determination of the residual sodium sulphite. This is a titrimetric method and is immediately available.
The BCI-S100-C is also available as a ready to use liquid BCI-L20-C, the dosages and residuals can be controlled exactly as described above.
