Heat Recovery System – SAFEHR
SAFEHR® is a safe heat recovery system designed to eliminate the risk of direct contact between sulfuric acid and pressurized water. It uses an inert buffer fluid to enable efficient heat exchange without acid dilution, undesired heat generation, or water contamination. The system can produce low to medium-pressure steam or pre-heat boiler feedwater for high-pressure operations, recovering up to 0.3 tons of steam per ton of acid produced. SAFEHR® can be applied to absorption towers or any process involving hazardous fluids.
Benefits Delivered by SAFEHR®
Inert Buffer Fluid
Non-toxic, stable, non-flammable, and immiscible with acid and water; excellent thermal properties.
Acid Leakage Detection
Any leakage is detected on the buffer side, preventing direct acid-water contact.
Controlled Corrosion
No acid dilution occurs, which minimizes corrosion risk and protects equipment integrity.
Compatible with Various Exchangers
Can be used with plate, shell-and-tube, spiral, and other heat exchanger types.
Safe Application in Critical Environments
Ideal for sulfuric acid absorption towers and other processes involving hazardous fluids.
High-Efficiency Steam Generation
Recovers energy from the exothermic reaction, generating up to 0.3 t of steam per ton of acid.
