Delayed Coker Unit Savings Best Practice


Delayed coker heater tube skin temperatures

Delayed Coker Heater Tube Skin Temperatures.

Delayed Cooker Units have heaters with tube skin thermocouples used to avoid over heating the tubes

Multiple temperature readings avoid localized overheating, coking and tube failure

Previously thermocouples failed or drifted over time

Reliable thermocouples enable one to make burner adjustments and clean burners to extend heater cycle


Current solutions are costly

Current Solutions are costly!

Costs to deal with coking in tubes can exceed $3 million per occurrence due to lost production during spalling and can happen several times per year

Running heaters at optimum conditions with better temperature accuracy increases run length between spalls by several months


Our results in service

Our Results in service

  • Large international energy company, installed 144 ExL thermocouples on 2 DCU heaters at one of their Texas refineries in March 2007

  • All thermocouples have been 100% operational since March 2007

  • These readings resulted in extended run length

  • No drift, failures, or other issues


Estimated savings

Estimated Savings

Total cost to purchase & install:
