Ammonium bisulfite Typical Properties

Ammonium bisulfite Usage

• Oilfield Chemicals & Water Treatment:

  • Oxygen Scavenger for Oilfield Injection: Extensively added to oilfield water injection and hydrostatic test fluids to rapidly scavenge dissolved oxygen, preventing microbial induced corrosion (MIC) and pitting corrosion in steel pipelines

  • Industrial Wastewater Dechlorination: Used as a reducing agent in industrial water treatment to neutralize residual chlorine, ozone, or peroxides prior to membrane filtration.

• Paper & Pulp Industry:

  • Chemical Pulping & Bleaching: Used in ammonium-based bisulfite pulping processes and as a bleaching/decolorizing auxiliary agent for cellulose fibers.

• Caramel Color & Food Industry:

  • Caramel Color Catalyst: Key ammonium/sulfite source used in the thermal caramelization process to manufacture Class IV food colorants.

• Chemical Synthesis & Textiles:

  • Reducing Agent & Intermediate: Used as a reducing agent in organic synthesis, dyestuff manufacturing, and sulfur dye application in textiles.
