💡 A Naphtha Pre-treater was retubed to improve metallurgy and reduce scale build-up. Follow-up IR scans revealed that the bottom pass in each set of manifolds was much hotter than the surrounding tubes. Due to overheating, rates were cut to reduce temperatures to safe operating ranges. A third-party simulation showed that the bottom passes had much lower flow rates, leading to hotter fluid and hotter tubes.
