Discover how a major refinery improved heat transfer efficiency by 24.3% without opening their exchanger bundles—thanks to ZymeFlow’s proven Rezyd-HP chemistry.  When a major refinery in southern Europe faced a heavily fouled crude/residue heat exchanger, they turned to ZymeFlow’s Rezyd-HP solution, a trusted chemistry from past successes. Without the ability to use circulation equipment, they chose a fill-and-soak method, relying on ZymeFlow’s expertise and chemistry. This case study demonstrates how strategic planning, innovative chemistry, and a commitment to excellence can deliver exceptional results, reducing downtime and restoring performance even in challenging conditions.
