INDUSTRIAL BOILERS

OXYGEN SCAVENGERS

CHEMIPOL® BO 30 and CHEMIPOL® BO 40 are two families that comprises a series of different oxygen scavengers based on catalyzed sulphites, hydrazine, carbohydrazide and DEHA, developed to protect water-steam circuits.

Water-steam circuits

CHEMIPOL BO 31
Oxygen scavenger

Formulation based on catalyzed sulphites. Components are listed in FDA section 173.310, as substances authorized to be used in the production of food contact steam.

Advantages:

  • Suitable for boilers in the food sector.
  • Accelerated reaction time with oxygen.

Application:

  • Low–medium pressure boilers.
  • Steam generators for the food industry.

CHEMIPOL BO 33
Oxygen scavenger

Aqueous solution of carbohydrazide with deoxygenating and passivating action on the metallic surfaces. Ferric oxide reacts to protective magnetite.

Advantages:

  • Alternative to hydrazine, safer and non-carcinogenic.
  • High reaction rate with oxygen.
  • It is volatile and does not contribute to the formation of solids in water.
  • Can be used in tempering.
  • Does not affect anionic or cationic resins.

Application:

  • Medium and high-pressure boilers and steam generators.
  • Protection of equipment out of service.
  • Protection and passivation of units during pre-operational, post-maintenance and after cleaning cycles.

CHEMIPOL BO 41
Oxygen scavenger

Volatile alkaline solution of diethyl hydroxylamine (DEHA) with deoxygenating and passivating action on the metallic surfaces for steam generation.

Advantages:

  • Oxygen release from feed water and condensate water.
  • Forms a protective coating on iron and copper surfaces with corrosion inhibitor effect.
  • Reduces iron and copper levels in feed water and condensates.
  • It does not increase the dissolved inorganic solids so the feed water can be used for tempering.
  • Minimal impact on steam purity and cationic conductivity.

Application:

  • Low and medium-pressure boilers.
  • High-pressure steam generators up to 125 bars.
  • Protection of boilers during shutdown or out of service.
