Sulfuric Acid Concentration Plant India 65% to 98% Acid Solution

Project Background

An Indian chemical plant required a reliable sulfuric acid concentration plant to process approximately 240 tons per day of dilute sulfuric acid at 65% concentration.

The goal was to achieve a stable output of 98% concentrated sulfuric acid for downstream industrial applications.

Key Challenge: Nitrate Impurities

One of the main technical challenges was the presence of nitrate compounds in the raw material, which can significantly impact system safety, corrosion resistance, and long-term stability.

Engineering Solution

To address these challenges, our engineering team developed a customized sulfuric acid concentration solution tailored for the Indian market.

• Pre-removal of water and nitrate compounds before concentration
• Stable operation under complex chemical conditions
• Corrosion-resistant design for long service life
• Optimized heat transfer efficiency

Future Expansion Capability

The system is designed with future scalability in mind. Interfaces for oleum (fuming sulfuric acid) production are reserved, allowing easy expansion without major modifications.

Project Results

• Stable production of 98% sulfuric acid
• Safe operation despite impurity presence
• Improved process reliability
• Flexible upgrade path for future capacity expansion

Conclusion

This project demonstrates how a well-designed sulfuric acid concentration plant in India can overcome complex raw material challenges while ensuring efficiency, safety, and long-term scalability.
