BOILER INTERNAL TREATMENT – POLYMERIC SOLUBILISING
BIT-L50-HP is a unique and specialized alkaline reacted polymer containing a “hexamer” comprising of polyacrylic; poly-organophosphorous, polymaleic, polysulphonic and other polymeric sequestering and organic absorption agents. It is specifically designed for the systematic control and removal of hardness deposits, organic foulants and metallic contaminants in steam generation systems and process pipework and vessels. Dosage is directly proportional to specific contaminants and direct test methods are available for ideal control of the product.
BIT-L50-HP is nominally controlled at between 200-300mg/l in the boiler circuit water. These dosages should be altered dependent upon feed water conditions; E.g.: High Hardness and/or Metallic Salts such as Fe; Cu etc.
mg/l BIT-L50-HP to boiler feed water = [ (Total Hardness in Feed x 1.44) + (1.89 x Fe in Feed) + (Residual Required/Effective Cycles of Concentration.)
There is a specific test method for the determination of the residual BIT-L50-HP. This is a titrimetric method and is immediately available.
BIT-L50-HP is also available as a spray dried powder – BIT-S98-HP. BIT-S98-HP can be diluted at 25% m/m and adding 10-20% sodium hydroxide lye (45-50% concentration). The residual is controlled at 200-300 mg/l in the boiler water, but effective dosage undertaken will be reduced by approximately 20%.
mg/l BIT-S98-HP 25% reconstituted powder blend + 10-20% NaOH lye to boiler feed water = 0.8 [(Total Hardness in Feed x 1.44) + Fe in Feed x 1.89) + (Residual Required/Effective Cycles of Concentration)]
