Furnace availability varies greatly from plant to plant and impacts the production levels, more so for the plants that are furnace constrained.
5 Leading Causes of Furnace Outages
  1. Radiant coils – carburization, stress/creep rupture are the leading causes followed by plugging, bowing/twisting and brittle fracture
  2. TLE cleaning – tube blockage
  3. Instrumentation
  4. TLE Repairs – contributing factors include water side corrosion, inlet tubesheet erosion, tube to tubesheet weld failure, gasket or seal failure
  5. Refractory repairs
Reliability of furnaces can vary significantly depending on:
  • Technology selection – including severity, selectivity, flexibility
  • Design approach, specifications and selection of components
  • Operation approach and discipline
  • Monitoring and process control
  • Maintenance approach and discipline
At Apex PetroConsultants, we focus on these aspects during all stages - including technology selection, modifications for performance improvements, design/engineering, operation and troubleshooting. Key is to maximize production at an optimum performance level and capital investment.
