SAFEHX Heat Exchange Technology
SAFEHX™ is a three-fluid heat exchanger designed to optimize the operation of the SAFEHR® process. Its exclusive technology uses a buffer fluid that operates in boiling and condensation cycles between the hot and cold sides, promoting continuous internal convection and efficient latent heat exchange. This mechanism eliminates the need for complex intermediate circuits, reducing system size and ensuring full safety against fluid mixing. With high heat transfer coefficients and a lower volume of safety fluid, SAFEHX™ is the ideal solution for critical applications, such as hydrogen plants, where preventing direct contact between process fluids is vital for safe operation.
Technical and Economic Benefits of SAFEHX
Safe Energy Recovery
Patented technology that recovers heat from SO₃ absorption with a physical barrier between sulfuric acid and water, reducing operational risks.
Elimination of Acid-Water Contact Risk
An inert and immiscible intermediate fluid prevents direct contact between water and acid in the event of a leak.
Greater Operational Safety
Significantly reduces the potential for critical events associated with acid dilution and hydrogen generation.
High Process Reliability
Multi-fluid configuration developed for continuous and stable operation under severe sulfuric acid industry conditions.
Efficient Steam Generation
Enables the production of low- and medium-pressure steam or the preheating of feedwater for high-pressure systems, maximizing energy utilization.
Early Leak Detection
Any failure is identified in the intermediate fluid circuit before contact occurs between the process fluids.
