Ammonium Bisulphite

Ammonium bisulphite (NH₄HSO₃) is a common chemical compound that has the ability to reduce and scavenge oxygen. Numerous industries, including the food, oil and gas, and water treatment sectors, depend heavily on this high-purity solution. For applications requiring deoxygenation, metal reduction, and pH adjustment, ammonium bisulphite is the material of choice due to its exceptional stability and efficiency.

Chemical Properties and Composition

Ammonium bisulphite has a strong sulfurous smell and is a clear to pale yellow liquid. It is an ammonium-hydrogen sulfite aqueous solution that is widely accessible in various quantities. Among the essential attributes are:

• Chemical Formula: NH₄HSO₃
• Molecular Weight: 99.10 g/mol
• Solubility: Highly soluble in water
• pH Range: Typically acidic (3-6)
• Stability: Stable when stored according to prescribed guidelines, but oxidation-sensitive

Industrial Applications

1. Water Treatment

Ammonium bisulphite is a common oxygen scavenger used in water treatment facilities to eliminate dissolved oxygen and stop corrosion in cooling systems, boilers, and pipelines.

2. Oil & Gas Industry

It acts as a deoxygenating agent in the petroleum sector to reduce corrosion in production and drilling machinery. Additionally, it serves in gas scrubbing procedures to eliminate dangerous impurities such as hydrogen sulfide.

3. Pulp & Paper Industry

Ammonium bisulphite serves in the pulp and paper industry as a reducing and bleaching agent during the manufacturing process.

4. Food & Beverage Industry

In food processing, especially in the wine and beer industries, ammonium bisulphite is used as an antioxidant and preservative to prolong shelf life and stop oxidation.

5. Chemical Manufacturing

It helps in the production of dyes, medications, and chemicals for photography, and it is a precursor in the synthesis of several sulfur-based compounds.

Advantages of Ammonium Bisulphite

• Incredibly powerful oxygen scavenger
• Prolongs the life of equipment via lowering corrosion
• An eco-friendly substitute for certain sulfur-based substances
• Economical and simple to manage
• Applications that are adaptable to many industries

Safe Handling and Storage

• Keep out of direct sunlight and in a cool, dry place.
• To stop oxidation, keep containers firmly sealed.
• Steer clear of heat and potent oxidizers.
• When handling, wear the proper protection gear.

Ammonium bisulphite is an essential chemical molecule that has many uses, especially in industrial processing, oil and gas, and water treatment.
