700 TPD Sulfuric Acid Plant Cooling 99% Concentrated Acid Heat Exchanger

Project Overview

The client built a new sulfuric acid plant with a capacity of 700 tons per day. The process requires cooling 99% concentrated sulfuric acid from 130°C to 70°C. The medium is highly corrosive under high temperature, bringing strict requirements for cooling equipment.

Core Technical Challenge

High-temperature 99% concentrated sulfuric acid has strong corrosivity. Ordinary heat exchangers face risks of rapid corrosion, frequent maintenance and unstable outlet temperature.

Equipment Selection & Solution

We recommend high-silicon stainless steel shell and tube heat exchanger. Shell side passes sulfuric acid, tube side carries cooling water. High-silicon material delivers outstanding anti-corrosion performance in hot concentrated acid, no extra anti-corrosion coating needed.

• Shell side for acid flow, tube side for cooling water, efficient heat exchange
• High silicon stainless steel, excellent corrosion resistance at high temperature
• No extra anti-corrosion coating, lower long-term operating cost
• Stable structure for uninterrupted mass production

Expected Operation Effects

• Stable outlet temperature ≤70°C all the time
• Long service life with minimal routine maintenance
• Fully match continuous 700TPD production demand

Conclusion

This cooling case solves high-temperature concentrated acid corrosion problems with high silicon stainless steel heat exchanger. It realizes stable temperature control, low maintenance and reliable long-term operation for sulfuric acid manufacturers.
