International Refinery Sees Measurable Operational Gains
A large international refinery recently reported significant operational improvements thanks to Curran-coated cooling water exchangers in its Fluid Catalytic Cracking (FCC) units. With more than 120 Curran-coated exchangers installed across the complex over the past decade, the refinery has consistently benefited from reduced fouling, enhanced reliability, and measurable process improvements.
Increased Cooling Capacity
Six overhead (O/H) trim exchangers demonstrated nearly 1,000 cubic meters per hour of additional cooling water capacity compared to previously installed uncoated exchangers. This increase in cooling efficiency enabled several critical operational improvements:
- Higher reactor feed temperatures – supporting optimal FCC reactions.
- Improved condensation – enhancing product recovery.
- Reduced propylene loss in fuel gas – preserving valuable product.
- Lower HP steam demand – reducing energy costs and emissions.
Beyond Corrosion Prevention
While the initial objective of the coating installation was to mitigate tube fouling and under-deposit corrosion, the refinery has enjoyed years without tube fouling maintenance. This highlights one of the most important advantages of Curran coatings: sustained, long-term protection with minimal downtime.
Operational and Business Impact
Coating exchangers doesn’t just protect equipment—it can also contribute directly to unit throughput and crude processing efficiency. In this refinery’s case, the operational improvements translated to measurable gains in FCC production and overall unit optimization.
Curran-Coated Exchangers Pay for Themselves
The combination of extended service life, reduced maintenance, and increased cooling capacity makes Curran coatings a smart investment for large-scale refining operations.
