A comparative guide: Ammonium bisulfite solution 30%, 65%, and 70%

When it comes to industrial-grade Ammonium Bisulphite/Bisulfite Solutions, the concentration levels, 30%, 65%, and 70%, play a crucial role in determining their suitability for specific applications. Each grade offers a distinct balance of performance, stability, and chemical reactivity, making it essential for industries to understand these differences before procurement.

As one of the Most Trusted Ammonium Bisulphite Solution Manufacturers in India, S.P. Chemicals has been delivering consistent quality to both domestic and international clients. Our solutions are widely supplied across multiple sectors, with a strong presence as a leading Ammonium Bisulphite Solution Supplier and Exporter in USA.

In this guide, we will take a closer look at Ammonium Bisulfite Solution 30%, Ammonium Bisulfite Solution 65%, and Ammonium Bisulfite Solution 70%, comparing their properties, applications, and advantages.

Ammonium Bisulphite Solution:

Ammonium Bisulphite/Bisulfite (NH₄HSO₃) is an aqueous solution of ammonium and Bisulfite/Bisulphite ions. It is valued for its reducing properties, oxygen scavenging abilities, and capability to react with dissolved oxygen in fluids. This makes it indispensable across industries such as oil & gas, water treatment, and chemical processing.

The percentage mentioned, 30%, 65%, or 70%, indicates the concentration of active Ammonium Bisulphite in the solution. The higher the concentration, the greater the reactivity and oxygen-scavenging capacity, but also the more stringent the handling and storage requirements.

1. Ammonium Bisulfite Solution 30%:

Ammonium Bisulfite Solution 30% offers a stable yet effective concentration ideal for operations that require moderate oxygen removal. This grade is widely used in:

• Water treatment plants: for oxygen control in boiler feedwater.
• Pulp & paper industry: as a pulping agent and preservative.
• Food-grade applications: for sulphite-based preservation.

Advantages:

• Lower reactivity compared to higher concentrations, making it safer to handle.
• Reduced corrosivity for equipment and pipelines.
• Cost-effective for processes that do not require maximum oxygen scavenging.
• For clients looking for a balance between efficiency and operational safety, Ammonium Bisulfite Solution 30% is an excellent choice.

2. Ammonium Bisulfite Solution 65%:

Ammonium Bisulfite Solution 65% is a higher concentration that delivers enhanced performance in oxygen removal and chemical reactions. Industries choose this grade when faster reaction rates and stronger oxygen scavenging are essential.

Applications:

• Oilfield operations: for deoxygenating injection water to prevent corrosion.
• Industrial water treatment: for processes that demand rapid oxygen elimination.
• Speciality chemical manufacturing: as a reducing agent in various synthesis processes.

Advantages:

• Increased efficiency in smaller dosages, reducing chemical consumption over time.
• Stronger performance in high-temperature and high-pressure environments.
• Widely available from top Ammonium Bisulphite Solution Manufacturers in India, ensuring a consistent supply.

3. Ammonium Bisulfite Solution 70%:

Ammonium Bisulfite Solution 70% is the most concentrated grade commonly available in the market. Known for its exceptional oxygen-scavenging capability, this grade is selected for the most demanding industrial applications.

Applications:

• Oil & gas industry – especially in offshore drilling and deep-well injection operations.
• High-capacity power plants – for rapid oxygen control in feedwater systems.
• Specialised chemical synthesis – where maximum reducing power is required.

Advantages:

• Delivers the highest efficiency per unit of solution.
• Minimises chemical injection frequency in continuous-feed systems.
• Preferred for challenging environments where lower grades might underperform.
• However, Ammonium Bisulfite Solution 70% demands meticulous handling, strict safety protocols, and precise dosing to avoid over-treatment.

Cost-Effectiveness	High for moderate needs	Balanced	High for intense needs
Best Suited For	General water treatment, paper & pulp, preservation	Oilfield operations, industrial treatment	Offshore drilling, high-demand chemical processes

 

Selecting the Right Concentration:

Choosing between Ammonium Bisulfite Solution 30%, 65%, and 70% depends on:

• Nature of the application: Is it general water treatment, high-pressure boiler feedwater, or oilfield injection?
• Operating environment: High temperatures and pressures favour higher concentrations.
• Safety considerations: Lower concentrations are safer for facilities without advanced handling systems.
• Cost vs performance balance: Higher concentrations can reduce dosing frequency but may require more stringent safety measures.
