DESCRIPTION
ACCOTREAT B 310 consists of sodium sulfite and specially selected catalyst to provide
an almost instantaneous oxygen removal even at low temperature. This product
will effectively prevent oxygen corrosion in boiler system.
FEATURES
- In view of its catalytic properties, it will provide excellent corrosion
inhibition
- High solubility
- Anhydrous
GENERAL SPECIFICATION
Appearance ………….…………… White free flowing powder
SG at 28° ……………………….… 0.72
Solubility ………………………..… 20% at 75° F
pH of 1% solution ……………...…. 9.5 to 10.5
TREATMENT
Prepared as a 5% solution, it is recommended to feed to the preboiler section
or direct to the boiler. Solution of catalysed sulfite must be covered with
a float to minimise contact with air. The dosage of catalysed sulfite is regulated
to maintain an excess of 30 ppm to 50 ppm of sulfite as SO3 in the boiler water.
HANDLING
Inhalation of dust should be avoided and the solution should not be taken internally.
