Case Study – Asset Reliability and Constraint Mitigation

Case Study – Asset Reliability and Constraint Mitigation

A North American refinery faced furnace monitoring challenges that limited coker operation. All tube skin thermocouples (TST) were out of service, IR thermography was impacted by heavy scale, and there was limited coker throughput. The objective was to resolve the inability to monitor tube skin temperatures.

Becht trained the operations staff to address scale formation through improved combustion management. The team also addressed TST design and installation mistakes, implemented maximum tube metal temperature models, and deployed advanced IR with improved image clarity.

Becht’s actions reduced scale formation, improved control, and deferred at least two decokes per year.

The client avoided decoke rate cuts that allowed for an additional $2MM/yr of throughput.
